Sensor experiment for measuring the hugging

I find the way that can measure the hugging when people hug the doll. For the scenario of my system. I use two dolls that can action and reaction to each other.  One doll represents sender action and another doll represents receiver action. It has a lot of the way to measure hugging force. But for my system, I want the arms of the receiver doll to have the reaction similar to the arms of sender action. So I choose to experiment flex sensor. The flex sensor can measure the angle (kind of) when we bend the sensor.

There are many ways to create flex sensor. I try to make the sensor from many materials.
