Vibration powered generator

Abstract

A vibration powered generator capable of vibrating at a plurality of resonance frequencies to generate electric power with a simpler structure is provided. A vibration powered generator has an elongated magnetostrictive material having one end attached to a vibrating body, in which the magnetostrictive material vibrates due to vibration of the vibrating body whereby the vibration powered generator generates electric power with the aid of an inverse magnetostrictive effect of the magnetostrictive material. A cross-sectional shape vertical to a longitudinal direction of the magnetostrictive material has an asymmetrical shape with respect to a straight line extending along a vibration direction thereof due to vibration of the vibrating body.
