Sew together conductive fabric and anti-static plastic to make your own fabric pressure sensor!
These step-by-step instructions will show you how to make your own fabric pressure sensor. It mentions two different variations, depending on if you use stretchy or non-stretchy fabric.
The materials used for the sensor are basically cheap and off-the-shelf. There are other places that sell conductive fabrics and Velostat, but LessEMF is a convenient option for both, especially for shipping within North America.
Velostat is the brand name for the plastic bags in which sensitive electronic components are packaged in. Also called anti-static, ex-static, carbon based plastic... (So you can also cut up one of these black plastic bags if you have one at hand. But caution! Not all of them work!)
To make the sensor fully fabric one can use EeonTex(TM) conductive textile (www.eeonyx.com) instead of the plastic Velostat, but at the moment EeonTex(TM) conductive textile is only available in a minimum of 100yds.
This is an improvement on the Flexible Fabric Touchpad Instructable
, using "iron-on" and plastic ex-static instead of the fabric which is less stable in maintaining resistance between the two conductive layers.
