Title:
発電素子および発電素子を備えた発電装置
Document Type and Number:
Japanese Patent JP4905820
Kind Code:
B2
Abstract:
The present invention provides a power generation element which has strong resistance to bending and impact and has high power generation capacity, and a power generation apparatus including the power generation element. The power generation element (1) includes: a first magnetostrictive rod (11a) made of a magnetostrictive material; a rigid rod (11b) made of a magnetic material and disposed in parallel with the first magnetostrictive rod (11a), the magnetic material having rigidity and a shape that enable uniform application of compression force or tensile force to the first magnetostrictive rod (11a); a first coil (12c) wound around the first magnetostrictive rod (11a); and two connecting yokes (10a and 10b) each of which is provided at one end of each of the first magnetostrictive rod (11a) and the rigid rod (11b) to connect the first magnetostrictive rod (11a) and the rigid rod (11b), wherein the power generation element (1) generates power through expansion or contraction of the first magnetostrictive rod (11a) due to vibration in a direction perpendicular to an axis direction of the first magnetostrictive rod (11a).
