Document Type and Number:
WIPO Patent Application WO/2023/181138
Kind Code:
A1
Abstract:
[Problem] To efficiently convert, into electric power, vibration generated due to natural phenomena, vibration generated due to artificial phenomena, and small vibration such as vibration generated due to natural phenomena, vibration generated due to artificial phenomena, or vibration generated intentionally or unconsciously by a person. [Solution] A power generation device according to an embodiment of the present invention comprises: a permanent magnet; a coil core made of a highly magnetically permeable material, disposed at a position through which a magnetic flux from the permanent magnet passes, and configured to include one or more projection parts projecting with respect to the permanent magnet; a coil wound around the coil core and configured to form a magnetic flux passage surface through which the magnetic flux from the permanent magnet is caused to pass; and an oscillation member configured to relatively oscillate the permanent magnet, the coil core, and the coil vertically and/or horizontally with respect to the magnetic flux passage surface.
