Abstract
An energy converter is formed by bonding a solid soft magnetic material and a solid magnetostrictive material. A vibration power generator is configured to generate power by means of the inverse magnetostriction effect of the magnetostrictive material produced by the vibration of a vibration unit configured using the energy converter. A force sensor device includes a force detection unit that detects magnetization change resulting from the inverse magnetostriction effect of the magnetostrictive material produced when a sensor unit configured using the energy converter deforms, and determines force acting on the sensor unit on the basis of the detected magnetization change. An actuator is configured to vibrate the vibration unit configured using the energy converter by means of the magnetostriction effect of the magnetostrictive material.
