ELECTRIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/089901
Kind Code:
A1
Abstract:
[Problem] To provide an electric device that has a simpler structure than the prior art and is capable of driving a load unit by performing self-power generation for converting vibrations, displacement, etc., from external force into power. [Solution] The electric device 100A of the present disclosure comprises: an electromagnetic induction coil 12; an elastic body 20 that contains a magnetized magnetic powder body 22, generates a magnetic field penetrating the electromagnetic induction coil 12, and exhibits a change in the magnetic flux density of the magnetic field when being elastically deformed upon receiving external force; a rectification unit 91 that rectifies an induced current induced in the electromagnetic induction coil 12 due to the change in the magnetic flux density; and a load unit 92 that is operated by receiving power from the rectification unit 91.
