Abstract
A contact sensor apparatus with improved sensitivity is provided. A frame defining a surface upon which contact detection is desired has two electrically conductive sheets held in spaced parallel relationship by a plurality of electrically non-conductive insulating spacers attached to the face thereof. A contact force distributor is sandwiched between the outside electrically conductive sheet and a graphics layer. Contact forces on the graphics layer, that are in alignment with the spacers, are redistributed to areas between adjacent spacers by the contact distributor.
