Nanomade is a company I met which builds force sensors with mapping using nano technology.
Comparing to classical FSR sensors:
- the mapping can be done (nano-tech)
- the cost is lower
- the sensor can be 3D printed
- since there is a resistive change, the time response is very fast.
Moreover, this company is Toulousaine (saucisse, rugby and red briquettes)
I let you imagine what can be done with this kind of sensors to make a good foot (or skin)
