FSRs i.e. Force Sensing Resistors are sensors that allow you to detect physical pressure, squeezing and weight. The FSR is made of 2 layers separated by a spacer. The more one presses, the more of those Active Element dots touch the semiconductor and that makes the resistance go down. FSRs are basically a resistor that changes its resistive value (in ohms Ω) depending on how much it is pressed. 

FSR has been pulled up by 5V and pulled down by 10K resistor (a simple voltage divider) so that when pressure is applied we get corresponding resistance as output.

Refer to the circuit diagram given below to make the FSR Feedback System

Connect one FSR  to Analog pin A5 to read Thumb force

Connect one FSR  to Analog pin A4 to read Palm force

This is how the circuit looks, after completion

For the making of the mother board involves assembling of various parts as given in the following link: https://myhumankit.org/en/tutoriels/myoelectric-exiii-hand/

In mother board Arduino micro is used as brain of the system. 

After mounting all the components on the mother board, this is how it looks.

The Temperature Sensitive Feedback System includes the working of system on two modes. When the system works on ‘T’ mode, the LED strip turns blue and red on touching any cold or hot object respectively. One can change the mode with a push on the touch button. On ‘F’ mode the user can experience fun of having colorful lights animation, which gives a cool disco effect! The LED strip was used as a bracelet on the hand.

Following is the block diagram for Temperature Sensitive Feedback System

Connect the temperature sensor to Arduino on pin A0
Connect the LED strip on pin D6
Connect "mode selection button" on pin 2

Then, upload the code "BionicHandTemperature_v4.ino" on your Arduino board.
You will find the file in Files folder.
