Title:
MAGNETOSTRICTIVE ELEMENT
Document Type and Number:
WIPO Patent Application WO/2023/276205
Kind Code:
A1
Abstract:
With conventional magnetostrictive elements, in U-shaped, cantilevered, double-sided, and other structures, a large load is applied near a fixing location or near an immovable location when subjected to vibration from an external source. Additionally, in terms of structural mechanics, shearing force quadratically decreases, simply, as the distance from the fixing location increases. To provide a magnetostrictive element with high overall power generation efficiency, this magnetostrictive element 1 has a longitudinal shape, and vibrates in a direction crossing the longitudinal direction to generate an inverse magnetostriction effect. In at least a portion of the magnetostrictive element 1, a curved shape 1b curving in the direction crossing the longitudinal direction is formed in multiple cycles along the longitudinal direction of the longitudinal shape.
