Abstract

There is provided an apparatus for sensing pressure. The apparatus may include a deformable layer being reversibly deformable by the pressure. The deformable layer may have a first side and a second side opposite the first side. The apparatus may also include an electrically-active (EA) layer disposed proximate the first side of the deformable layer. The EA layer may have an electrical property that is reversibly changeable when the EA layer is subjected to the pressure. Moreover, the apparatus may include a plurality of pins being electrically conductive and each having a first end and a second end opposite the first end. The pins may extend from the second side, through the deformable layer, to the first side such that the pins electrically contact the EA layer proximate the first ends. The electrical property may be measurable between a pair of the pins.
