Abstract
Assemblies include a chassis having a first side configured to receive a force-sensitive surface, a support structure including first electrode portions, and resilient mounting elements attached to the chassis and to the support structure. The mounting elements include second electrode portions positioned adjacent to the first electrode portions. Force-sensitive systems include force sensors including portions of a support structure and portions of a mounting element that are adapted to relatively move responsive to one or more applied forces, and a controller configured to identify the one or more applied forces by determining movement between the support structure and the mounting element. Methods include detecting changes in capacitances of respective capacitors formed by first electrode portions on a support structure and second electrode portions defined by mounting elements coupling a chassis to the support structure. Force values and force locations are determined from the detected changes in capacitances.
