Another great soft circuit tutorial by Hannah Perner-Wilson:
Pressure sensors on your fingertips intended for use by children and their piano teachers to visualize the difference between “p” piano (soft) and “f” forte (hard). The pressure sensitive layers of fabric in the fingertips of these gloves are stretchy so that they can fit tightly.
The sensors are made from stretch conductive fabric and piezoresistive Eeonyx fabric. The glove is connected to the Arduino via metal snaps and a fabric cable made from sewn conductive thread traces.
