Abstract:
1. A touch sensor apparatus, comprising: a substrate; a plurality of first electrodes disposed on the substrate; a dielectric layer disposed on the plurality of first electrodes; a plurality of second electrodes disposed on the dielectric layer; a plurality of intermediate conductors disposed on the dielectric layer and configured for electrical communication with the first electrodes through vias formed in the dielectric layer; a layer of force-sensitive resistor (FSR) material disposed on the second electrodes and the intermediate conductors; and a plurality of conductive bridges disposed on the FSR material, each of the conductive bridges being disposed above at least one of the intermediate conductors, wherein the FSR material is configured to form at least one substantially vertical electrical connection between one of the conductive bridges, one of the second electrodes, and one of the intermediate conductors when a force is applied to the FSR material.
