Title: PIEZOELECTRIC SENSOR
Abstract:
The present invention provides a piezoelectric sensor having elastic properties in a surface direction thereof, whereby movement of a body to be measured can be accurately measured while smoothly following elongation of the body to be measured, and whereby movement in the surface direction of a surface of the body to be measured on which the piezoelectric sensor is arranged can also be detected. This piezoelectric sensor is characterized by having a piezoelectric sheet containing a porous synthetic resin sheet, a signal electrode layer layered on one surface of the piezoelectric sheet and including electroconductive fine particles and a binder resin having elastic properties, and a ground electrode layer layered on the other surface of the piezoelectric sheet and including electroconductive fine particles and a binder resin having elastic properties.
