ABSTRACT:
A multi-zone capacitive force sensing apparatus/method is disclosed. In one embodiment, an apparatus includes one or more capacitors each having an upper conductive surface and a lower conductive surface substantially parallel to the upper conductive surface, a housing with a top plate and a bottom plate to encompass the capacitors, and a sensor in the housing to generate a measurement based on a change in a distance between the upper conductive surface and the lower conductive surface of each of the capacitors when a contact zone of the top plate associated with the each of the plurality of capacitors is deflected by a force applied on the contact zone. The apparatus may also include a comparison module associated with the sensor to generate a signal indicating unevenness of a force applied on the top plate when there is any significant difference between measurements of the capacitors.
