Title:
MAGNETOSTRICTIVE MATERIAL, ENERGY CONVERSION MEMBER, METHOD FOR MANUFACTURING SAME, AND VIBRATION POWER GENERATOR
Document Type and Number:
WIPO Patent Application WO/2023/176869
Kind Code:
A1
Abstract:
[Problem] To provide a magnetostrictive material, an energy conversion member, a method for manufacturing same, and a vibration power generator, wherein good energy efficiency is achieved, and manufacturing costs can be reduced. [Solution] A magnetostrictive material has voids. A plate-like magnetostrictive material has through holes in the plate thickness direction. The plate-like magnetostrictive material, which has through holes in the plate thickness direction, and a plate member are laminated in the plate thickness direction to form an energy conversion member. The plate-like magnetostrictive material has a honeycomb structure in which cells constitute through holes. The cells in the honeycomb structure have polygonal-shaped cross-sections. The plate member is made of a magnetostrictive material, a soft magnetic material, or a non-magnetic material. The plate-like magnetostrictive material and/or the plate member are made up of a plurality of pieces and are laminated in the plate thickness direction.
