Pressure Sensor/Matrix Kit (2010)

Using neoprene, Velostat, conductive thread and stretch conductive fabric to construct a fabric bend sensor.
Velostat is a piezoresistive plastic film that reacts to pressure with a decrease in resistance. This sensor can be constructed to be a single pressure sensor or a pressure sensor matrix comprising four seperate sensors.

Materials included:

– stretch conductive fabric >> http://lessemf.com/fabric.html
– above comes with fusible iron-on adhesive backing from local fabric shop
– Velostat >> http://lessemf.com/plastic.html
– silverized nylon thread 117/17 2ply >> http://www.fine-silver-productsnet.com/shmeya2.html
– 1.5mm thick HS quality neoprene >> http://sedochemicals.de/ or http://www.foamorder.com/neoprene.html

Here is an example of a basic circuit sewn with conductive thread that uses the neoprene pressure sensor to turn an LED light on and make it shine brighter, the harder it is pressed.
