Abstract:
1. A capacitive device, comprising: a flexible circuit substrate dimensionally stable up to a first temperature; a first plurality of conductive pads disposed on the flexible circuit substrate; a transparent sensor substrate that is dimensionally stable up to a second temperature; a second plurality of conductive pads disposed on the transparent sensor substrate, wherein a first pad of the first plurality of conductive pads is coupled to a first pad of the second plurality of conductive pads; a first plurality of transparent sensing elements disposed on the transparent sensor substrate, wherein a first sensing element of the plurality of transparent sensing elements is communicatively coupled to the first pad of the second plurality of conductive pads; and a second plurality of transparent sensing elements disposed on the transparent sensor substrate, wherein a first sensing element of the second plurality of transparent sensing elements is communicatively coupled to a second pad of the second plurality of conductive pads, wherein the first and second plurality of transparent sensing elements are disposed on a same side of the transparent sensor substrate, and configured to detect changes in capacitance.
