hello everyone so three years ago one of
my classmates got burned during the
chemistry accident he were pressure
sleeves during his recovery stage in
order to help him recover better and he
told me that it was really uncomfortable
for him to wear such pressure sleeves
and so I bought one pressure garment
online and I try it by myself he was
correct
it was indeed really uncomfortable to
wear such things because it was
extremely tight and patrons have to wear
it all day long so in order to help him
feel better in his recovery stage I did
some research online about burn
treatment I read a lot of papers and I
saw speech made by a renowned burn
expert in the speech he talked about the
burn treatment and the pressure therapy
he said that current pressure therapy
has a lot of has a lot of inaccuracies
and further improvement should be done
to help make it better
and so I try to like a lot of research
online and read a lot of papers about
burn treatment and I managed to write a
paper by myself
I collected a paper and I stand a lot of
emails to different professors in burn
treatment field the email address was
attached to the research papers they
present online and I waited for their
response sadly no one replied it was the
next morning when I received an email
from the head professor in Shanghai
Hospital she was - had one of the top
researchers in burn treatment field and
I was so surprised that she was willing
to support me in this reply she said
that my idea was really good and she was
willing to support me to do further
research in this burn treatment field
and so she invited me to Shanghai
Hospital and I talked to a lot of
patients in Shanghai Hospital in our
talk I learned that current currently
pressures are
has been used in a lot of medical field
and it is used to help these burn
patients recover better after their
scars have appeared and so I feel a
little strange because a lot of doctors
they told me that the tighter the
clothes is the more pressure it will
exert on human body and the better the
patient will recover I felt a little
strange is this true
so I contacted several experiments and
this is one of the experiments that that
I have made so these are the two
balloons they are completely identical
however one is blow to be bigger and one
is smaller they are conducted by a tube
and there's a veil between them which is
closed right now and so I'm going to
open that veil and see what happened
raise your hand if we think that after
when the veil is opened these blue two
balloons will became the same size okay
so that's what will happen
well the results show that actually they
won't be the same the big balloon will
actually become bigger and a small dome
watch it becomes smaller why is that
this result actually reveals different
this results actually reveals the
principle behind pressure and how it
works
pressure is determined by both the
tensile force of fabric and the
curvature of you of the object that is
the shape of the object so the air will
flow from a high pressure object you a
low pressure object and in this case
from the big one from the small one to
the bigger one and this means that in
the burn treatment fields every patient
have different body curvature and that
is body shape and to address this
problem I think of using the 3d
technology because 3d technology has
already been applied in a lot of medical
fields such as orthopedics but it hasn't
been applied in burn treatment yeah and
the 3d technology is actually a great
way to help these patients and a great
way to customize the pressure garments
for each individual patients and so I
have to develop some 3d scanning systems
because it is not it hasn't been applied
in this field yet and these are the five
3d scanners that I have used in my
project and I contacted researches and
experiments to test test them and choose
one between them to like trying to find
out which one is the best a lot of
people actually question my word cuz
they think that these sensors maybe they
are too cheap and a girl like me cannot
figure out these things by myself I must
get some help from others and it was
kind of hard trying to convince them off
but instead of arguing them by words I
try to use experiments and lot of data
speaks by itself
so this is the pressure mask that I've
made this is the result of my product
it's a prototype I went to the Shanghai
hospital and I saw a lot of patients
there I got close with them and heard
about your stories I first met so many
years ago at Shanghai hospital she was a
26 year old mother she was a 26 year old
mother who was severely burned in a
factory accident during work I saw I
first saw her wake up after her 15 hour
operation with white cast covering all
her body except for her eyes and mouth
left visible she has suffered from
extreme pain only the instinct to
survive supported her doctor well I die
I don't want to die
she cried seeing the hopelessness and
suffering Selma has I wanted to help her
using the technology after below the
straited technology and so I try to work
with hospitals in hospitals and the
doctors and so I I also talk with the
burn victims to make sure that my Prada
has actually meet their needs
it was kind of hard but I managed to do
so my project was the success adds a
theoretical base and it was on the
broadcasted on national TV I felt great
up
I feel great proud of myself at a time
thinking that I can actually make a
change to people's lives thinking that I
can actually make this permutation sleep
better however things were not as simple
as I thought when can I use her pressure
max Sammy asked me with great excitement
the next time we met can I use it right
now
Sally I had to tell her that she cannot
because my project was only a research
phase and you're still a long way to go
before it can be commercialized
therefore I feel great disappointed
because I fell to produce a product that
was perfect
that can be put into practice directly I
saw her I saw her still suffering from
pain because although Sami has escaped
that straddled us now right now but she
still cannot take care of herself
because of this adhesion between her
fingers she looks so disappointed and
the moment that I stepped out of the
hospital I was determined I have to help
her I have to make my project and make
it into something that can be really
applied in real life instead of just of
costly prototype and so I went for a lot
of specialists in software and I asked
for help from 3d printed material
companies and at last my prototype
actually works this August
summing was once again in the hospital
to have her fifth on the skin operation
and she told me that she was really
proud of me because she can actually use
my pressure max at that time before she
tried out her pressure mask she showed
me a photo of her and her daughter in
the photo she and her daughter was
laughing and how to each other's hands
I still hope in her eyes I see her one
day she will be able to hugging her
daughter again I used to think of
engineering only as only something
that's you like you build something and
to innovate something but now seeing the
stories of Selmy and other burn victims
I realized that engineering is more than
that engineering is something that you
can use to make actually make a society
pattern and use it to make the world a
better place for every person to live in
this and also there's a third sentence
that that I love Engineering for
Humanity and it stays my dream of like
devoting myself in academic research
while also use my time to have
humanitarian endeavors we have to
understand humanities before creating
things and use technologies to change
the world so
yes done talking to you guys about my
research project but it was more than a
project for me right now
I want suka I want you guys to know
about the living conditions of burn
patients and the struggles they have
suffered like when they are trying to
reenter the society and I also want you
guys to know that every idea has the
power to shape the road it's it's not
impossible for our teenagers like us to
actually make something and use the
technology to change the world it's not
that that's far away from us to actually
build something and apply it in real
life and after all I want to I want to
say something to you guys and that is
you're never too young to change the
world thank you
[Applause]
