Pressure-sensitive element having sufficient expandability, a wide measurement range of pressure force, and a simple structure, and an electronic device using the pressure-sensitive element

Abstract

Provided is a pressure-sensitive element having more sufficient expandability, a relatively wide measurement range of pressure force, and a relatively simple structure, and an electronic device using the pressure-sensitive element. The pressure-sensitive element includes a plurality of first electrodes being elongated in first direction, arranged in a first plane, and including a conductive elastic body, a plurality of second electrodes being elongated in second direction intersecting the first direction, arranged in a second plane facing the first plane, and including a conductor wire, and a plurality of dielectrics covering a surface of the plurality of second electrodes. The plurality of second electrodes have bent parts K arranged periodically, and capacitance at intersections of the plurality of first electrodes and the plurality of second electrodes changes in accordance with pressure force applied between the plurality of first electrodes and the plurality of second electrodes.
