the pressure sensor would detect an increase in pressure caused by body weight

When I laid out my plan, I realized that I faced three main challenges:

ื›ืฉื—ืฉื‘ืชื™ ืขืœ ื”ืชื•ื›ื ื™ืช ืฉืœื™, ื”ื‘ื ืชื™ ืฉืขืžื“ืชื™ ื‘ืคื ื™ ืฉืœื•ืฉื” ืืชื’ืจื™ื:
03:16
first, creating a sensor;

196425

ืจืืฉื™ืช: ืœื™ืฆื•ืจ ื—ื™ื™ืฉืŸ;

than I initially had thought it to be.
66
204927
2055
ืžืฉื—ืฉื‘ืชื™ ื‘ื”ืชื—ืœื”.
03:26
First, I had to create a wearable sensor that was thin and flexible enough

ืจืืฉื™ืช, ื”ื™ื™ืชื™ ืฆืจื™ืš ืœื™ืฆื•ืจ ื—ื™ื™ืฉืŸ ืœื‘ื™ืฉ ืฉื”ื™ื” ื“ืง ื•ื’ืžื™ืฉ ืžืกืคื™ืง

After extensive research and testing of different materials like rubber,

03:36
which I realized was too thick to be worn snugly on the bottom of the foot,

I decided to print a film sensor

Once pressure is applied, the connectivity between the particles increases.

03:48
Therefore, I could design a circuit that would measure pressure
