従来技術、競合技術の概要(英語) BACKGROUND ART
Conventionally, the vibration of the routine for performing power generation from a technique has been developed and have been actively carried out, the state of the art as one of a power generation method using piezoelectric elements or a change in magnetic flux density of the permanent magnet using a known method of power generation.
A substantial number of power generation method using piezoelectric elements which, in any manner to the piezoelectric element by applying a force from outside, the deformation of the piezoelectric element will generate power. In order to make the piezoelectric element is deformed, for example, a piezoelectric element to deform the vibration by a method, such as wind or sound pressure of a method for imparting pressure indirectly, such as a piezoelectric element to output the collision object, modifying a method of adhering a piezoelectric element on the object and the like (for example, see Patent document 1). In Patent document 1, sound pressure fluctuations of the air by using the piezoelectric element generates power by the power generation apparatus according to the lunar month, and, by means of changing the pressure vibrations in the piezoelectric element generates power by the electric power generator and the vibration are described.
In addition, change in magnetic flux density of the permanent magnet is a power generation method, the vibration of the permanent magnet according to the temporal change of the coil to develop a method to perform , i.e., a power generation method using the electromagnetic induction (for example, non Patent document 1, Patent Literature 2 reference).
In non patent document 1, the inside of the coil in the direction parallel to the direction of the magnetization by the permanent magnet to vibrate, which changes the magnetic flux density of the coil, the coil current is generated in the power generation is performed by the power generation element is disclosed.
In Patent document 2, the bias magnet and magnetized to 2 poles, by applying a force from the outside by the effect of the reverse distortion of the magnetic flux is changed so that the magnetic permeability and a change in the magnetostrictive material, magnetostrictive material having a magnetic anisotropy in the direction of the compression means and periodically, periodically changing magnetic flux (induction) by a coil current in the organic unit in accordance with a power generating element is disclosed. Is the power generating element, wherein a periodically changing magnetic flux and a, a coil wound around a coil linkage to the pellet, with a magnetostrictive material, a coil, compression means are disposed therein. That is, having a magnetic anisotropy in the longitudinal direction of the magnetostrictive material, and is periodically compressed in the longitudinal direction, when the current generated at the coil is generating electric power by an arrangement.
