Zoned Proximity Sensing with a double-woven Fabric and an Interleaved Conductive Grid

This textile was woven by Christy Matson. There are many applications of this approach. Here I show that it can be used for zoned proximity sensing using a qprox capacitance sensing chip. Pressure sensing can be achieved by felting in a resistive felt at the intersections.

Tablo etextile fabric drape sensing controller

This controller with no direct antecedents is made by draping conductive stretchable fabric over a cereal bowl creating a curve related to the famous one called the witch [sic] of Agnesi.
Resistive strips around the bowl are shorted out by the fabric and the varying resistances are
measured and sent via USB to control software on a host computer.
