Title:
MAGNETOSTRICTIVE VIBRATIONAL POWER GENERATOR
Document Type and Number:
WIPO Patent Application WO/2023/068053
Kind Code:
A1
Abstract:
A magnetostrictive vibrational power generator that obtains power using the magnetostriction effect produced in a magnetostriction element 13, and is obtained by comprising: a beam member 10 that has one end configured as a free end and the other end configured as a fixed end, and is integrally provided with a rod-shaped magnetostriction element 13 and a frame 12 to which the magnetostriction element 13 is mounted; magnets 14a, b that impart a magnetic bias to the magnetostriction element 13; a coil 15 that is wound around the magnetostriction element 13 so as to be penetrated by the magnetic flux produced by the magnetostriction element 13 to which the magnetic bias has been applied; and a rotational tab member 20 that is positioned near the beam member 10, and is obtained by arranging, at prescribed intervals on an outer circumferential section of a rotational body 21, a plurality of tab sections 23 which pull the free end of the frame 12 such that the magnetostriction element 13 sags.
