This week I focused on building the circuit on the feet, and I think my progress is on track. This circuit is supposed to be able to detect pressure. Our team chose to accomplish this by building a pressure sensor, and I built a voltage divider with the sensor and a resistor. With the different amounts of pressure, the resistance of the pressure sensor will be changed, and by measuring the voltage in between the pressure sensor and the resistor, I will be able to get the amount of force applied to the pressure sensor.
My contribution to this project is the physical part of the vest and the circuit of the lower pressure system, I will analysts and evaluate them by seeing if they are functional.
For the next week, I plan to implement the code for the pressure sensor with Arduino, and I found an article online explaining a similar subject to this.
