Abstract

See full text

A system and method for measuring pressure by using two substrates that are separated by a distance, each substrate having at least one electrode, and wherein touch sensor capacitance circuitry coupled to electrodes on each of the substrates and transmitting a drive signal may be used to detect a bending or deflection of at least one of the substrates by measuring a change in distance between the electrodes on the different substrates when pressure is applied to one of the substrates, and wherein a compressible substrate may be disposed between the two substrates.
