Can materials be mechanisms? | Alexandra Ion | TEDxPoznan


hi today I want to ask the question what

hi today I want to ask the question what if the material was the machine and this

if the material was the machine and this

if the material was the machine and this is kind of one instance a small preview

is kind of one instance a small preview

is kind of one instance a small preview that I wanted to show you of what we

that I wanted to show you of what we

that I wanted to show you of what we mean and we call this whole concept

mean and we call this whole concept

mean and we call this whole concept metamaterial mechanisms and I want to

metamaterial mechanisms and I want to

metamaterial mechanisms and I want to talk up a little bit more extensively

talk up a little bit more extensively

talk up a little bit more extensively about that you see it in action it’s a

about that you see it in action it’s a

about that you see it in action it’s a fully functional door latch that is

fully functional door latch that is

fully functional door latch that is printed in one piece so let’s go a

printed in one piece so let’s go a

printed in one piece so let’s go a little bit back we fabricate a lot of

little bit back we fabricate a lot of

little bit back we fabricate a lot of things these days and 3d printing is

things these days and 3d printing is

things these days and 3d printing is Justin standing for any other

Justin standing for any other

Justin standing for any other fabrication method at this point so what

fabrication method at this point so what

fabrication method at this point so what is really great to have about having

is really great to have about having

is really great to have about having physical objects is that you can for

physical objects is that you can for

physical objects is that you can for example print things for educational

example print things for educational

example print things for educational purposes you can you can print asset DNA

purposes you can you can print asset DNA

purposes you can you can print asset DNA string and look at it from different

string and look at it from different

string and look at it from different perspectives you can touch it you can

perspectives you can touch it you can

perspectives you can touch it you can feel it you for mechanical things you

feel it you for mechanical things you

feel it you for mechanical things you can disassemble them reassemble them you

can disassemble them reassemble them you

can disassemble them reassemble them you can print things that have different

can print things that have different

can print things that have different material properties that are soft rough

material properties that are soft rough

material properties that are soft rough you know rigid or flexible and you can

you know rigid or flexible and you can

you know rigid or flexible and you can also print things that that you can wear

also print things that that you can wear

also print things that that you can wear things that are really personalized to

things that are really personalized to

things that are really personalized to you like this 3d printed cast that is

you like this 3d printed cast that is

you like this 3d printed cast that is breathable so there’s no itching anymore

but one thing that these three things

but one thing that these three things had in common was that they were

had in common was that they were

had in common was that they were actually concerned with the outside of

actually concerned with the outside of

actually concerned with the outside of the object so if we just recap it was

the object so if we just recap it was

the object so if we just recap it was about shape shape and shape now here

about shape shape and shape now here

about shape shape and shape now here comes the one kicker which actually sets

comes the one kicker which actually sets

comes the one kicker which actually sets 3d printer printing apart from other

3d printer printing apart from other

3d printer printing apart from other manufacturing techniques it allows us to

manufacturing techniques it allows us to

manufacturing techniques it allows us to arrange matter very freely in space so

arrange matter very freely in space so

arrange matter very freely in space so then it might ask what about the inside

then it might ask what about the inside

then it might ask what about the inside of the objects right and it turns out

of the objects right and it turns out

of the objects right and it turns out that researchers in computer graphics

that researchers in computer graphics

that researchers in computer graphics for example already did it they in this

for example already did it they in this

for example already did it they in this example they were

example they were

example they were designing the structure on the inside so

designing the structure on the inside so

designing the structure on the inside so that the safe material but but the

that the safe material but but the

that the safe material but but the object this remains as strong as it was

object this remains as strong as it was

object this remains as strong as it was before in this case for example they

before in this case for example they

before in this case for example they left out parts of the inside just didn’t

left out parts of the inside just didn’t

left out parts of the inside just didn’t feel it

feel it

feel it so this Dino with this huge hat can

so this Dino with this huge hat can

so this Dino with this huge hat can actually stand on this teeny tiny feet

actually stand on this teeny tiny feet

actually stand on this teeny tiny feet so they were actually moving the center

so they were actually moving the center

so they were actually moving the center of gravity but there by designing the

of gravity but there by designing the

of gravity but there by designing the inside of the object rather than the

inside of the object rather than the

inside of the object rather than the outside of the object and here’s another

outside of the object and here’s another

outside of the object and here’s another example where it’s kind of like a

example where it’s kind of like a

example where it’s kind of like a similar example but it’s about the

similar example but it’s about the

similar example but it’s about the rotation so you can make arbitrary

rotation so you can make arbitrary

rotation so you can make arbitrary shapes rotate reliably like this

shapes rotate reliably like this

shapes rotate reliably like this elephant now center of gravity moment of

elephant now center of gravity moment of

elephant now center of gravity moment of inertia these are things that you also

inertia these are things that you also

inertia these are things that you also learn in school in physics classes if

learn in school in physics classes if

learn in school in physics classes if you remember they’re known right I mean

you remember they’re known right I mean

you remember they’re known right I mean you can design the insert that’s cool

you can design the insert that’s cool

you can design the insert that’s cool but it’s that’s kind of it’s not

but it’s that’s kind of it’s not

but it’s that’s kind of it’s not exciting right um but what about if we

exciting right um but what about if we

exciting right um but what about if we have this possibility to arrange matter

have this possibility to arrange matter

have this possibility to arrange matter freely in space can we engineer for

freely in space can we engineer for

freely in space can we engineer for unusual properties like properties that

unusual properties like properties that

unusual properties like properties that are just not happening in nature one

are just not happening in nature one

are just not happening in nature one example is this one it looks very easy

example is this one it looks very easy

example is this one it looks very easy kind of just a sheet with a lot of holes

kind of just a sheet with a lot of holes

kind of just a sheet with a lot of holes but as you compress it downwards regular

but as you compress it downwards regular

but as you compress it downwards regular materials would expand in the other

materials would expand in the other

materials would expand in the other direction

direction

direction but you see that this one is clearly not

but you see that this one is clearly not

but you see that this one is clearly not expanding right its needs rather

expanding right its needs rather

expanding right its needs rather contracting in the perpendicular

contracting in the perpendicular

contracting in the perpendicular direction to where it was compressed and

direction to where it was compressed and

direction to where it was compressed and this is a really unusual property here

this is a really unusual property here

this is a really unusual property here you see the same concept but um just

you see the same concept but um just

you see the same concept but um just fold it from from a piece of paper so

fold it from from a piece of paper so

fold it from from a piece of paper so origami folding and what’s really

origami folding and what’s really

origami folding and what’s really interesting about this is that you see

interesting about this is that you see

interesting about this is that you see that the person just you know moves the

that the person just you know moves the

that the person just you know moves the hands in one axis and one dimension

hands in one axis and one dimension

hands in one axis and one dimension but the sheet actually folds up in two

but the sheet actually folds up in two

but the sheet actually folds up in two dimensions and that turns out to be

dimensions and that turns out to be

dimensions and that turns out to be really useful for space so you can you

really useful for space so you can you

really useful for space so you can you can package solar panels really small

can package solar panels really small

can package solar panels really small and then move with an easy

and then move with an easy

and then move with an easy kinnison you can unfold it by pulling in

kinnison you can unfold it by pulling in

kinnison you can unfold it by pulling in one direction and it unfolds into the

one direction and it unfolds into the

one direction and it unfolds into the two dimensions and that’s really useful

two dimensions and that’s really useful

two dimensions and that’s really useful so if we go back to this one example

so if we go back to this one example

so if we go back to this one example that I saw before I I told you that you

that I saw before I I told you that you

that I saw before I I told you that you know there’s just simple circles it

know there’s just simple circles it

know there’s just simple circles it doesn’t look very complicated but no one

doesn’t look very complicated but no one

doesn’t look very complicated but no one holds it back and designing the circles

holds it back and designing the circles

holds it back and designing the circles to have like any other shape and then

to have like any other shape and then

to have like any other shape and then and then when you compress the whole

and then when you compress the whole

and then when you compress the whole thing it kind of make an make it Bend in

thing it kind of make an make it Bend in

thing it kind of make an make it Bend in weird directions and this is a concept

weird directions and this is a concept

weird directions and this is a concept that is called mechanical metal

that is called mechanical metal

that is called mechanical metal materials which are artificial

materials which are artificial

materials which are artificial structures with mechanical properties

structures with mechanical properties

structures with mechanical properties defined by the structure rather than the

defined by the structure rather than the

defined by the structure rather than the composition and with composition they

composition and with composition they

composition and with composition they mean the chemical composition kind of

mean the chemical composition kind of

mean the chemical composition kind of the material it’s actually made of you

the material it’s actually made of you

the material it’s actually made of you know be it wood or plastics or metal

know be it wood or plastics or metal

know be it wood or plastics or metal it’s really about the structures so far

it’s really about the structures so far

it’s really about the structures so far metal materials have been understood as

metal materials have been understood as

metal materials have been understood as materials what if we think of them as

materials what if we think of them as

materials what if we think of them as machines and this is exactly the

machines and this is exactly the

machines and this is exactly the instantiation that I showed you in the

instantiation that I showed you in the

instantiation that I showed you in the very beginning as a small preview we

very beginning as a small preview we

very beginning as a small preview we think of these materials where we

think of these materials where we

think of these materials where we designed a structure at the same time

designed a structure at the same time

designed a structure at the same time they’re not materials they’re machines

they’re not materials they’re machines

they’re not materials they’re machines so if you walk through this example real

so if you walk through this example real

so if you walk through this example real quick you see that the user is pushing

quick you see that the user is pushing

quick you see that the user is pushing down the handle and that creates a

down the handle and that creates a

down the handle and that creates a rotation around the axis down there next

rotation around the axis down there next

rotation around the axis down there next to the handle this thing turn lets the

to the handle this thing turn lets the

to the handle this thing turn lets the shearing cells in the middle shear and

shearing cells in the middle shear and

shearing cells in the middle shear and they then hole in the bolt that lets you

they then hole in the bolt that lets you

they then hole in the bolt that lets you open the door now let’s just quickly

open the door now let’s just quickly

open the door now let’s just quickly review a traditional toilet so again you

review a traditional toilet so again you

review a traditional toilet so again you push down the handle that creates a

push down the handle that creates a

push down the handle that creates a rotation around the axle which charges

rotation around the axle which charges

rotation around the axle which charges the handle spring which is behind that

the handle spring which is behind that

the handle spring which is behind that thing and at the same time rotates the

thing and at the same time rotates the

thing and at the same time rotates the lever which then pulls in the bold and

lever which then pulls in the bold and

lever which then pulls in the bold and charges the latch spring so you see the

charges the latch spring so you see the

charges the latch spring so you see the kind

kind

kind you know a lot of parts involved here

you know a lot of parts involved here

you know a lot of parts involved here um I counted them for you with six in

um I counted them for you with six in

um I counted them for you with six in this case and I also counted to wonder

this case and I also counted to wonder

this case and I also counted to wonder that we proposed and that’s one part so

that we proposed and that’s one part so

that we proposed and that’s one part so you see one main benefit is that it

you see one main benefit is that it

you see one main benefit is that it requires no assembly so you can actually

requires no assembly so you can actually

requires no assembly so you can actually give it out to users and they just take

give it out to users and they just take

give it out to users and they just take it out of the printer and and it works

it out of the printer and and it works

it out of the printer and and it works really nicely and one more thing that

really nicely and one more thing that

really nicely and one more thing that excites me about this about this concept

excites me about this about this concept

excites me about this about this concept is that me is a computer scientist we

is that me is a computer scientist we

is that me is a computer scientist we can actually the function is solely

can actually the function is solely

can actually the function is solely defined by the geometry so that and you

defined by the geometry so that and you

defined by the geometry so that and you know the computers are pretty good at

know the computers are pretty good at

know the computers are pretty good at you know processing geometry and stuff

you know processing geometry and stuff

you know processing geometry and stuff so what you see here is actually a 3d

so what you see here is actually a 3d

so what you see here is actually a 3d editor that we built for allowing users

editor that we built for allowing users

editor that we built for allowing users to to design such mechanisms and we it’s

to to design such mechanisms and we it’s

to to design such mechanisms and we it’s the editor is online we published it on

the editor is online we published it on

the editor is online we published it on github for anyone who wants to program

github for anyone who wants to program

github for anyone who wants to program further and there’s the source code and

further and there’s the source code and

further and there’s the source code and also we upload it all the models that we

also we upload it all the models that we

also we upload it all the models that we printed and I will show you on

printed and I will show you on

printed and I will show you on Thingiverse so I want to give you now a

Thingiverse so I want to give you now a

Thingiverse so I want to give you now a little bit more detail of how this thing

little bit more detail of how this thing

little bit more detail of how this thing actually works and what’s what type of

actually works and what’s what type of

actually works and what’s what type of cells we use so to do that I use a

cells we use so to do that I use a

cells we use so to do that I use a simpler example which is displayers here

simpler example which is displayers here

simpler example which is displayers here so you see the work like this as you

so you see the work like this as you

so you see the work like this as you press it they go down to they they move

press it they go down to they they move

press it they go down to they they move towards each other and what you see here

towards each other and what you see here

towards each other and what you see here is that um we partition this thing into

is that um we partition this thing into

is that um we partition this thing into a regular grid of cells and all the

a regular grid of cells and all the

a regular grid of cells and all the cells look like can look like this in

cells look like can look like this in

cells look like can look like this in the rigid cells we just use the square

the rigid cells we just use the square

the rigid cells we just use the square sing of the square with the diagonal and

sing of the square with the diagonal and

sing of the square with the diagonal and that and that results in

that and that results in

that and that results in in a triangle which is a very stable

in a triangle which is a very stable

in a triangle which is a very stable structure so it doesn’t move in any way

structure so it doesn’t move in any way

structure so it doesn’t move in any way and with these cells you can make a

and with these cells you can make a

and with these cells you can make a product for the rigid parts of the of

product for the rigid parts of the of

product for the rigid parts of the of the object now the other thing the more

the object now the other thing the more

the object now the other thing the more interesting cells are the so-called

interesting cells are the so-called

interesting cells are the so-called shearing cells and they’re even simpler

shearing cells and they’re even simpler

shearing cells and they’re even simpler so you just leave out the one diagonal

so you just leave out the one diagonal

so you just leave out the one diagonal so that means that they can actually

so that means that they can actually

so that means that they can actually move now and they move in a very

move now and they move in a very

move now and they move in a very controlled direction so the only shear

controlled direction so the only shear

controlled direction so the only shear and having multiple of those gives us

and having multiple of those gives us

and having multiple of those gives us the whole area that we need for this

the whole area that we need for this

the whole area that we need for this mechanism now because we have no um

mechanism now because we have no um

mechanism now because we have no um listen to assemble like everything is

listen to assemble like everything is

listen to assemble like everything is based on bending and this is actually

based on bending and this is actually

based on bending and this is actually based on our on an idea from industry

based on our on an idea from industry

based on our on an idea from industry which is called living hinge so you make

which is called living hinge so you make

which is called living hinge so you make things from one part and this hinge here

things from one part and this hinge here

things from one part and this hinge here it’s just that you make the material

it’s just that you make the material

it’s just that you make the material thinner and that allows it to flex and

thinner and that allows it to flex and

thinner and that allows it to flex and this is actually used in industry quite

this is actually used in industry quite

this is actually used in industry quite a bit for example these things or bottle

a bit for example these things or bottle

a bit for example these things or bottle caps

caps

caps tik-tok packaging you know I’m sure

tik-tok packaging you know I’m sure

tik-tok packaging you know I’m sure you’ve seen them already so if we simply

you’ve seen them already so if we simply

you’ve seen them already so if we simply base on if we simply base all the

base on if we simply base all the

base on if we simply base all the mechanisms you know the first naive

mechanisms you know the first naive

mechanisms you know the first naive approach on on the idea of having living

approach on on the idea of having living

approach on on the idea of having living hinges then it would look something like

hinges then it would look something like

hinges then it would look something like this so you have like the cells and then

this so you have like the cells and then

this so you have like the cells and then you make like a thin part of the

you make like a thin part of the

you make like a thin part of the material so it’s able to move and it

material so it’s able to move and it

material so it’s able to move and it would look like this but the problem is

would look like this but the problem is

would look like this but the problem is because you have so little material

because you have so little material

because you have so little material there it would be very weak and just

there it would be very weak and just

there it would be very weak and just tear so what we actually set out is that

tear so what we actually set out is that

tear so what we actually set out is that we use this sheering cells and we kind

we use this sheering cells and we kind

we use this sheering cells and we kind of replicate many many of these small

of replicate many many of these small

of replicate many many of these small living hinges so that so that the

living hinges so that so that the

living hinges so that so that the objects are able to take more force and

objects are able to take more force and

objects are able to take more force and this is what we call a Hindu ray and the

this is what we call a Hindu ray and the

this is what we call a Hindu ray and the thing is that it the whole array moves

thing is that it the whole array moves

thing is that it the whole array moves up sorry moves this one now if you

up sorry moves this one now if you

up sorry moves this one now if you enclose this hinge array with in rigid

enclose this hinge array with in rigid

enclose this hinge array with in rigid parts

parts

parts then you get something that that has the

then you get something that that has the

then you get something that that has the property that the the opposing members

property that the the opposing members

property that the the opposing members stay parallel and if we look at this

stay parallel and if we look at this

stay parallel and if we look at this example it is actually already the

example it is actually already the

example it is actually already the pliers so they move together as you move

pliers so they move together as you move

pliers so they move together as you move the other parts together and looks like

the other parts together and looks like

the other parts together and looks like this so you just give to the members

this so you just give to the members

this so you just give to the members different geometry to make up for the

different geometry to make up for the

different geometry to make up for the handles and the brackets and essentially

handles and the brackets and essentially

handles and the brackets and essentially this is a hinge

this is a hinge

this is a hinge it’s pliers but just made from one part

it’s pliers but just made from one part

it’s pliers but just made from one part no axial now if you take multiple of

no axial now if you take multiple of

no axial now if you take multiple of these hinge arrays and just like chain

these hinge arrays and just like chain

these hinge arrays and just like chain them up you can get something that’s

them up you can get something that’s

them up you can get something that’s actually pretty surprising so this is a

actually pretty surprising so this is a

actually pretty surprising so this is a thing that replicates your drawing but

thing that replicates your drawing but

thing that replicates your drawing but it’s just like one piece of material

it’s just like one piece of material

it’s just like one piece of material [Music]

and if you do more complicated things

and if you do more complicated things with with multiple layers and so on you

with with multiple layers and so on you

with with multiple layers and so on you kind of get this this walking robot that

kind of get this this walking robot that

kind of get this this walking robot that is just made in one piece this is the

is just made in one piece this is the

is just made in one piece this is the rendition of the young zum Walker which

rendition of the young zum Walker which

rendition of the young zum Walker which is also known as strand based maybe to

is also known as strand based maybe to

is also known as strand based maybe to some of you okay but let’s go in a

some of you okay but let’s go in a

some of you okay but let’s go in a little bit deeper so we actually

little bit deeper so we actually

little bit deeper so we actually understand what’s going on here because

understand what’s going on here because

understand what’s going on here because there’s not always just benefits but

there’s not always just benefits but

there’s not always just benefits but also limitations to a system so in this

also limitations to a system so in this

also limitations to a system so in this case you see that the user actually puts

case you see that the user actually puts

case you see that the user actually puts in some force into the system into the

in some force into the system into the

in some force into the system into the storage and then as the as the handle

storage and then as the as the handle

storage and then as the as the handle rotates it pushes the cells next to it

rotates it pushes the cells next to it

rotates it pushes the cells next to it they push the cell next to them and they

they push the cell next to them and they

they push the cell next to them and they push the cell next to them and so forth

push the cell next to them and so forth

push the cell next to them and so forth however at every step at every

however at every step at every

however at every step at every transition from one cell to the other

transition from one cell to the other

transition from one cell to the other you lose some energy so that means that

you lose some energy so that means that

you lose some energy so that means that the force that was put in by the user

the force that was put in by the user

the force that was put in by the user when he when he pushed on the handle is

when he when he pushed on the handle is

when he when he pushed on the handle is not the same that goes into the bolt

not the same that goes into the bolt

not the same that goes into the bolt that is pulled in which is fine for this

that is pulled in which is fine for this

that is pulled in which is fine for this example but we were kind of thinking you

example but we were kind of thinking you

example but we were kind of thinking you know as computer scientists what about

know as computer scientists what about

know as computer scientists what about digital signals something that that

digital signals something that that

digital signals something that that behaves like black Domino you know you

behaves like black Domino you know you

behaves like black Domino you know you put you put many of them in a row and if

put you put many of them in a row and if

put you put many of them in a row and if the align properly they can go on and on

the align properly they can go on and on

the align properly they can go on and on and on there’s no energy decay so we

and on there’s no energy decay so we

and on there’s no energy decay so we actually set out and created some of

actually set out and created some of

actually set out and created some of these digital metamaterials and these

these digital metamaterials and these

these digital metamaterials and these cells look slightly more complicated

cells look slightly more complicated

cells look slightly more complicated than once they showed it before and they

than once they showed it before and they

than once they showed it before and they embed a spring and that one stores

embed a spring and that one stores

embed a spring and that one stores energy and I will just show you this is

energy and I will just show you this is

energy and I will just show you this is a called a bi-stable spring so it’s the

a called a bi-stable spring so it’s the

a called a bi-stable spring so it’s the concept of for example if you have a

concept of for example if you have a

concept of for example if you have a credit card

credit card

credit card you push your fingers together and it’s

you push your fingers together and it’s

you push your fingers together and it’s happening in this position but if you

happening in this position but if you

happening in this position but if you push it over it’s also happy in this

push it over it’s also happy in this

push it over it’s also happy in this position and because it’s bent it stores

position and because it’s bent it stores

position and because it’s bent it stores some energy and you need a slight push

some energy and you need a slight push

some energy and you need a slight push and it jumps over to the other state on

and it jumps over to the other state on

and it jumps over to the other state on its own and this is kind of what we did

its own and this is kind of what we did

its own and this is kind of what we did here with

here with

here with these slightly more complicated Springs

these slightly more complicated Springs

these slightly more complicated Springs so you push them from the side and then

so you push them from the side and then

so you push them from the side and then the one cell jumps over to its other

the one cell jumps over to its other

the one cell jumps over to its other state pushes the next cell that jumps

state pushes the next cell that jumps

state pushes the next cell that jumps over to its other state pushes the next

over to its other state pushes the next

over to its other state pushes the next cell and so on and every time it jumps

cell and so on and every time it jumps

cell and so on and every time it jumps over it releases energy its own energy

over it releases energy its own energy

over it releases energy its own energy that it has stored and because every

that it has stored and because every

that it has stored and because every cell stores its own energy there’s no

cell stores its own energy there’s no

cell stores its own energy there’s no decay so the output could be somewhere

decay so the output could be somewhere

decay so the output could be somewhere over there and because you can see every

over there and because you can see every

over there and because you can see every cell is like a tiny battery of fissile

cell is like a tiny battery of fissile

cell is like a tiny battery of fissile will it kind of releases like this now

will it kind of releases like this now

will it kind of releases like this now what we did with this is for example you

what we did with this is for example you

what we did with this is for example you see this black door latch it’s the same

see this black door latch it’s the same

see this black door latch it’s the same thing that you just saw in pink but we

thing that you just saw in pink but we

thing that you just saw in pink but we edit a door lock where you enter digits

edit a door lock where you enter digits

edit a door lock where you enter digits and the computation is also done based

and the computation is also done based

and the computation is also done based on a material that we that would edit so

on a material that we that would edit so

on a material that we that would edit so again everything is integrated into the

again everything is integrated into the

again everything is integrated into the cell structure of the object and here I

cell structure of the object and here I

cell structure of the object and here I just want to give you a quick overview

just want to give you a quick overview

just want to give you a quick overview this signal transmission so we can

this signal transmission so we can

this signal transmission so we can transmit signals as I just showed you we

transmit signals as I just showed you we

transmit signals as I just showed you we can route signals differently around the

can route signals differently around the

can route signals differently around the corner this is very important we can

corner this is very important we can

corner this is very important we can validate signals so we can block signals

validate signals so we can block signals

validate signals so we can block signals because otherwise if the code would be

because otherwise if the code would be

because otherwise if the code would be wrong to the input it would always open

wrong to the input it would always open

wrong to the input it would always open this is not desirable but we can

this is not desirable but we can

this is not desirable but we can actually evaluate if that is correct the

actually evaluate if that is correct the

actually evaluate if that is correct the codes that he entered and then we can

codes that he entered and then we can

codes that he entered and then we can also duplicate signals and make them

also duplicate signals and make them

also duplicate signals and make them move more so in conclusion the one

move more so in conclusion the one

move more so in conclusion the one take-home message that I that I wanted

take-home message that I that I wanted

take-home message that I that I wanted to share with you is that we actually

to share with you is that we actually

to share with you is that we actually think of materials of metamaterials

think of materials of metamaterials

think of materials of metamaterials being machines rather than just

being machines rather than just

being machines rather than just materials and the idea is that you see

materials and the idea is that you see

materials and the idea is that you see this pink thing here you could think

this pink thing here you could think

this pink thing here you could think that

that

that it’s the mechanism but if you go on and

it’s the mechanism but if you go on and

it’s the mechanism but if you go on and make this hold or you print the hold or

make this hold or you print the hold or

make this hold or you print the hold or with the mechanism just with these cells

with the mechanism just with these cells

with the mechanism just with these cells you just used rigid cells that you also

you just used rigid cells that you also

you just used rigid cells that you also use on a handle and in the bolt so the

use on a handle and in the bolt so the

use on a handle and in the bolt so the question is where does the material

question is where does the material

question is where does the material start and where does the mechanism start

start and where does the mechanism start

start and where does the mechanism start we think that they become

we think that they become

we think that they become indistinguishable from each other and I

indistinguishable from each other and I

indistinguishable from each other and I just showed you this at hand of two

just showed you this at hand of two

just showed you this at hand of two examples so it’s materials that actually

examples so it’s materials that actually

examples so it’s materials that actually incorporate the embed mechanical

incorporate the embed mechanical

incorporate the embed mechanical functions and I sure to this other

functions and I sure to this other

functions and I sure to this other example where materials actually embed

example where materials actually embed

example where materials actually embed computational functions and this is what

computational functions and this is what

computational functions and this is what I think of being a new perspective on

I think of being a new perspective on

I think of being a new perspective on smart matter so you give them with

smart matter so you give them with

smart matter so you give them with materials more wisdom in a way that they

materials more wisdom in a way that they

materials more wisdom in a way that they can be mechanisms they can be small

can be mechanisms they can be small

can be mechanisms they can be small computers but they don’t need

computers but they don’t need

computers but they don’t need electronics and it’s only done on the on

electronics and it’s only done on the on

electronics and it’s only done on the on the level of having the material

the level of having the material

the level of having the material structure that resolves all of that for

structure that resolves all of that for

structure that resolves all of that for you with this you know I was talking in
