Abstract
A flexible passive capacitance pressure sensor includes a first polymeric substrate and a second polymeric substrate. An elastic dielectric sensing material is positioned between the inner-facing surface of the first polymeric substrate and the inner-facing surface of the second polymeric substrate. A first plurality of wires are positioned on the outer-facing surface of said first polymeric substrate, and a second plurality of wires positioned on the outer-facing surface of said second polymeric substrate. The plurality of wires form a flexible capacitor. With the reduced profile enabled by such a capacitor, the flexible passive capacitance pressure sensor can have a thickness of less than 200 microns.
