US Patent 12135252 Force sensor with conductive films

A force sensor includes: a sensor sheet having a first surface and a second surface on an opposite side to the first surface; a substrate facing the first surface; a first adhesive layer interposed between the substrate and the sensor sheet and made of an anisotropic conductive material; and a plurality of array electrodes interposed between the substrate and the first adhesive layer and separated from each other. The first surface of the sensor sheet is bonded to the first adhesive layer. The first adhesive layer has conductivity in a thickness direction and has insulation properties in a planar direction along a plane.
