experiments and learned two major things skin Anatomy and skin care the turning
skin Anatomy and skin care the turning
skin Anatomy and skin care the turning point came in 2015 in the summer of 2015
point came in 2015 in the summer of 2015
point came in 2015 in the summer of 2015 there was a powder explosion at high
there was a powder explosion at high
there was a powder explosion at high water park this incident caused many
water park this incident caused many
water park this incident caused many deaths and injuries and a lot of victims
deaths and injuries and a lot of victims
deaths and injuries and a lot of victims suffer from a large area of skin
suffer from a large area of skin
suffer from a large area of skin so we started to think you already had a
so we started to think you already had a
so we started to think you already had a skincare product on our hands well stay
skincare product on our hands well stay
skincare product on our hands well stay away we can modify and change that into
away we can modify and change that into
away we can modify and change that into something that could help the victims we
something that could help the victims we
something that could help the victims we tried to modify our angel mask into an
tried to modify our angel mask into an
tried to modify our angel mask into an artificial skin so what is an artificial
artificial skin so what is an artificial
artificial skin so what is an artificial skin in cases of large area skin loss
skin in cases of large area skin loss
skin in cases of large area skin loss artificial skin can serve as a barrier
artificial skin can serve as a barrier
artificial skin can serve as a barrier layer to protect the one and thus induce
layer to protect the one and thus induce
layer to protect the one and thus induce regeneration of the dermis which is the
regeneration of the dermis which is the
regeneration of the dermis which is the second layer of our skin okay so there
second layer of our skin okay so there
second layer of our skin okay so there is actually a huge demand for artificial
is actually a huge demand for artificial
is actually a huge demand for artificial skin the evidence let’s look at some
skin the evidence let’s look at some
skin the evidence let’s look at some statistics in 2016 there were nearly
statistics in 2016 there were nearly
statistics in 2016 there were nearly 500,000 skin burn cases in the US alone
500,000 skin burn cases in the US alone
500,000 skin burn cases in the US alone and these skin burn cases cost more than
and these skin burn cases cost more than
and these skin burn cases cost more than two hundred thousand US dollars to treat
two hundred thousand US dollars to treat
two hundred thousand US dollars to treat successfully besides many patients
successfully besides many patients
successfully besides many patients suffer from large area of skin loss due
suffer from large area of skin loss due
suffer from large area of skin loss due to other diseases such as diabetes
to other diseases such as diabetes
to other diseases such as diabetes eczema or sunburn with this in mind we
eczema or sunburn with this in mind we
eczema or sunburn with this in mind we started modify our facial masks into an
started modify our facial masks into an
started modify our facial masks into an artificial skin so to begin with our
artificial skin so to begin with our
artificial skin so to begin with our project the first thing we need to do is
project the first thing we need to do is
project the first thing we need to do is to determine the ingredients that is
to determine the ingredients that is
to determine the ingredients that is Venus who have enough formula and
Venus who have enough formula and
Venus who have enough formula and luckily we got 15 ingredients from our
luckily we got 15 ingredients from our
luckily we got 15 ingredients from our facial masks with each Heslin has an own
facial masks with each Heslin has an own
facial masks with each Heslin has an own unique properties that is beneficial to
unique properties that is beneficial to
unique properties that is beneficial to our skin then we narrowed down to 15
our skin then we narrowed down to 15
our skin then we narrowed down to 15 ingredients to two ingredients which is
ingredients to two ingredients which is
ingredients to two ingredients which is sodium alginate and San tanco sodium
sodium alginate and San tanco sodium
sodium alginate and San tanco sodium alginate is extracted from a cell wall
alginate is extracted from a cell wall
alginate is extracted from a cell wall found seaweed and sank as a sugar there
found seaweed and sank as a sugar there
found seaweed and sank as a sugar there are typically from corn and wheat
are typically from corn and wheat
are typically from corn and wheat well with this in mind we started to
well with this in mind we started to
well with this in mind we started to design artificial skin and our design
design artificial skin and our design
design artificial skin and our design has a middle layer a top layer and a
has a middle layer a top layer and a
has a middle layer a top layer and a bottom layer the middle layer is the
bottom layer the middle layer is the
bottom layer the middle layer is the artificial skin and it’s made of sodium
artificial skin and it’s made of sodium
artificial skin and it’s made of sodium alginate and so I think um the top layer
alginate and so I think um the top layer
alginate and so I think um the top layer is a waterproof layer and the bottom
is a waterproof layer and the bottom
is a waterproof layer and the bottom layer oh we have a PowerPoint back yeah
layer oh we have a PowerPoint back yeah
layer oh we have a PowerPoint back yeah and the bottom layer is a calcium
and the bottom layer is a calcium
and the bottom layer is a calcium chloride layer and going back let’s look
chloride layer and going back let’s look
chloride layer and going back let’s look at the definition of artificial skin in
at the definition of artificial skin in
at the definition of artificial skin in cases of large areas of skin nose
cases of large areas of skin nose
cases of large areas of skin nose artificial skin can serve as a barrier
artificial skin can serve as a barrier
artificial skin can serve as a barrier layer to protect the wound and does
layer to protect the wound and does
layer to protect the wound and does induce regeneration of the dermis we
induce regeneration of the dermis we
induce regeneration of the dermis we have also after doing some research we
have also after doing some research we
have also after doing some research we came up with with some criteria of a
came up with with some criteria of a

preventing the precipitation of
preventing the precipitation of ingredients after gel is formed we found
ingredients after gel is formed we found
ingredients after gel is formed we found that the gel is sticky and when thinking
that the gel is sticky and when thinking
that the gel is sticky and when thinking of the application it would be difficult
of the application it would be difficult
of the application it would be difficult and uncomfortable for the user to remove
and uncomfortable for the user to remove
and uncomfortable for the user to remove it from the wood therefore we decided to
it from the wood therefore we decided to
it from the wood therefore we decided to apply four percent calcium chloride
apply four percent calcium chloride
apply four percent calcium chloride solution on to the service of the gel
solution on to the service of the gel
solution on to the service of the gel and due to some chemical bonding
and due to some chemical bonding
and due to some chemical bonding adhesiveness of our artificial skin is
adhesiveness of our artificial skin is
adhesiveness of our artificial skin is reduced we have also developed a
reduced we have also developed a
reduced we have also developed a waterproof layer this waterproof layer
waterproof layer this waterproof layer
waterproof layer this waterproof layer can house to prevent in the irritation

can house to prevent in the irritation caused by bacteria in water so now that
caused by bacteria in water so now that
caused by bacteria in water so now that we’ve introduced you to the basic
we’ve introduced you to the basic
we’ve introduced you to the basic principles of artificial skin we’ll have
principles of artificial skin we’ll have
principles of artificial skin we’ll have a demonstration to show you how it’s
a demonstration to show you how it’s
a demonstration to show you how it’s actually made
so yes start and as mentioned the
so yes start and as mentioned the ingredients we use our sodium alginate
ingredients we use our sodium alginate
ingredients we use our sodium alginate and I think oh and these are the
and I think oh and these are the
and I think oh and these are the ingredients first sodium alginate is
ingredients first sodium alginate is
ingredients first sodium alginate is everything a powder are mixed together
everything a powder are mixed together
everything a powder are mixed together with boiling water until homogeneous
with boiling water until homogeneous
with boiling water until homogeneous hydrogel is formed which is this one and
hydrogel is formed which is this one and
hydrogel is formed which is this one and due to time constraints we’ve already
due to time constraints we’ve already
due to time constraints we’ve already prepared a gel general who now
prepared a gel general who now
prepared a gel general who now demonstrate the remaining steps the
demonstrate the remaining steps the
demonstrate the remaining steps the sodium alginate and xanthan gum solution
sodium alginate and xanthan gum solution
sodium alginate and xanthan gum solution is poor in turn mode and the one we’re
is poor in turn mode and the one we’re
is poor in turn mode and the one we’re using here is made from the 3d printer
using here is made from the 3d printer
using here is made from the 3d printer at our school
and this is to prevent any bumps or
and this is to prevent any bumps or bubbles from forming in the final
bubbles from forming in the final
bubbles from forming in the final product and after you’re satisfied with
product and after you’re satisfied with
product and after you’re satisfied with that calcium chloride can be added and a
that calcium chloride can be added and a
that calcium chloride can be added and a submission this reduces adhesiveness
after that this character fish’s skin
after that this character fish’s skin can be cut out from the mold
and
and that is our product
join us now flipping it to the other
join us now flipping it to the other side to apply more calcium chloride
yeah so that’s our artificial skin and
yeah so that’s our artificial skin and we’ll put it aside for now we’re now
we’ll put it aside for now we’re now
we’ll put it aside for now we’re now demonstrate making the waterproof layer
demonstrate making the waterproof layer
demonstrate making the waterproof layer the waterproof layer is made using
the waterproof layer is made using
the waterproof layer is made using sodium alginate and hydrochloric acid
sodium alginate and hydrochloric acid
sodium alginate and hydrochloric acid and due to higher constraints we’ve
and due to higher constraints we’ve
and due to higher constraints we’ve already prepared the solution the sodium
already prepared the solution the sodium
already prepared the solution the sodium alginate solution is poured into a petri
alginate solution is poured into a petri
alginate solution is poured into a petri dish
and at this point you have to make sure
and at this point you have to make sure you’re being very careful because you
you’re being very careful because you
you’re being very careful because you don’t want any bubbles and bumps
don’t want any bubbles and bumps
don’t want any bubbles and bumps informing and after that is done we can
informing and after that is done we can
informing and after that is done we can add two hydrochloric acid
and that is the first CD of a waterproof
and that is the first CD of a waterproof layer but that actually has to we have
layer but that actually has to we have
layer but that actually has to we have to actually wait five minutes to
to actually wait five minutes to
to actually wait five minutes to adaptive form and we have a finished
adaptive form and we have a finished
adaptive form and we have a finished product here for you to see and this is
product here for you to see and this is
