ABSTRACT:
A sensor element formed of PZT is overlapped onto an actuator formed of electrostrictive elements, and both members are pinched between a rigid body that is not deformed. By impressing an alternating-current signal to the actuator, the sensor element is deformed in accordance with the amount of deformation thereof to use the thus generated electromotive force of the sensor element as a signal for the absolute value calculation.
