Document Type and Number:
WIPO Patent Application WO/2023/068508
Kind Code:
A1
Abstract:
Disclosed is an energy harvesting device based on electromagnetic induction, the device generating electric energy by converting external force applied in the vertical direction into rotational motion. The disclosed energy harvesting device using electromagnetic induction comprises: a housing with an open top; a plate, which is arranged at the top of the housing and moves in a bottom direction of the housing by means of external force; a first elastic body; a first vertical movement part moving in the bottom direction of the housing by means of the plate, and moving in the top direction of the housing by means of the first elastic body; a first rotational movement part for converting vertical movement of the first vertical movement part into rotational movement; a magnet part rotating by means of the first rotational movement part; and a coil part, which includes a coil and is arranged to be adjacent to the magnet part.
