Today with the range of new technical fabric that we have access, we can recreate some physical effect in electronic like sensors with variable resistivity.

Combining good conductor fabric and bad conductor fabric (resistive), you can easily create a pressure sensor.


Some example of tutorial to make this kind of sensors.
Neoprene pressure sensor
Neoprene bend sensor

When the sensor is made you can plug it into a simple circuit to see is effect on a led or with a multimeter but to increase the possibilities, you can use microcontroller to interface it and read it.

In this class, we will learn to use arduino and more precisely a lilypad (the textile version of arduino.
