[imsolidstate] built his own pressure sensitive mat. It utilizes two discs of copper clad board with a piece of foam in between for each of 64 sensors. As the foam gets compressed, the capacitance ...

In module 1 you will learn how to specify and use various types of pressure sensors for an embedded circuit. First, you will learn about piezoresistive, capacitive, and vacuum sensors. This includes a ...

[James Eckert] got his hands on a Freescale MPR121 capacitive touch sensor. The chip in question ... and making more complicated pressure-sensing keyboards, whenever you need something super ...
