Title:
POWER GENERATING ELEMENT AND POWER GENERATING DEVICE USING POWER GENERATING ELEMENT
Document Type and Number:
Japanese Patent JP2023108946
Kind Code:
A
Abstract:
To provide a power generating element the power generation efficiency of which can be improved when power generation using a magnetostriction material is performed, and provide a power generating device using the power generating element.SOLUTION: A power generating element disclosed in the present description includes a magnetostriction plate one end in the longitudinal direction of which is fixed and which includes a magnetostriction material, a coil including at least a portion of the magnetostriction plate, and a magnetic field generation part which is disposed on the magnetostriction plate and generates a magnetic field. The power generating element is configured to generate power upon application of a force to the magnetostriction plate. The power generating element further includes a yoke including a ferromagnetic body, and a magnetic field adjustment part including a ferromagnetic body. The yoke is disposed outside the coil, and is at least partially fixed to the magnetostriction plate. The magnetic field adjustment part is included in a portion of the coil, and is disposed near a surface, of the magnetostriction plate, opposed to the surface to which the magnetic field generation part is fixed.SELECTED DRAWING: Figure 1
