Configurable Force-Sensitive Input Structure for Electronic Devices

Abstract:

A configurable, force-sensitive input structure for an electronic device is disclosed. The input structure has a metal contact layer, a sense layer positioned below the metal contact layer, and a drive layer capacitively coupled to the sense layer. The input structure may also have a compliant layer positioned between and coupled to the sense layer and the drive layer, a rigid base layer positioned below the drive layer, and a set of supports positioned between the metal contact layer and the rigid base layer.
