|Title||Power generation element and power generation apparatus provided with power|
Disclosed are: a power generation element that has a strong resistance against bending and impact, and that generates a large amount of power; and a power generation apparatus provided with the power generation element.
The power generation element (1) is provided with a first magnetostriction rod (11a) comprised of a magnetostrictive material; a rigid rod (11b) that is comprised of a magnetic material having rigidity and shape necessary for applying a uniform compressive/tensile force to the first magnetostriction rod (11a), and that is arranged to be parallel with the first magnetostriction rod (11a); a first coil (12c) wound around the first magnetostriction rod (11a); and two interconnecting yokes (10a, 10b) arranged at both ends of the first magnetostriction rod (11a) and the rigid rod (11b) such that the two rods are interconnected.
Power is generated, by having the first magnetostriction rod (11a) expanded or contracted with the vibration thereof in a direction perpendicular to the axis direction thereof.
