Abstract
An energy harvester using electromagnetic induction includes: a magnet portion; a coil portion including a coil and disposed around the magnet portion, a rotational movement part configured to rotate the magnet portion or the coil portion, a lever configured to rotate the rotational movement part, an external force transmitter that is moved toward the lever by an external force to rotate the lever in a first direction about a rotation shaft of the lever and transmits the external force to different points of the lever according to a magnitude of the external force, and an elastic body configured to rotate the lever in a second direction.

An energy harvester using electromagnetic induction, comprising:
- a magnet portion;
- a coil portion including a coil and disposed around the magnet portion;
- a rotational movement part configured to rotate the magnet portion or the coil portion;
- a lever configured to rotate the rotational movement part;
- an external force transmitter that is moved toward the lever by an external force to rotate the lever in a first direction about a rotation shaft of the lever and transmits the external force to different points of the lever according to a magnitude of the external force;
- and
- an elastic body configured to rotate the lever in a second direction.
An energy harvester using electromagnetic induction, comprising:
- a substrate;
- a magnet portion;
- a coil portion including a coil and disposed around the magnet portion;
- a rotational movement part configured to rotate the magnet portion or the coil portion on the substrate and including at least one gear;
- a lever configured to rotate the rotational movement part;
- an external force transmitter that is moved toward of the lever by an external force to rotate the lever in the first direction around the rotation shaft of the lever;
- an elastic body configured to rotate the lever in a second direction;
- and
- a ball bearing configured to reduce friction between the gear and the substrate or between the magnet portion and the coil portion.
An energy harvesting block using electromagnetic induction, comprising:
- at least one energy harvester;
- a housing in which the energy harvester is disposed and of which an upper portion is open;
- and
- an upper cover coupled to the upper portion of the housing to seal the housing and elongated in an inner direction of the housing by an external force,
- wherein an energy harvester includes:
- a magnet portion;
- a coil portion including a coil and disposed around the magnet portion;
- a rotational movement part configured to rotate the magnet portion or the coil portion;
- a lever configured to rotate the rotational movement part;
- an external force transmitter that is moved toward the lever by the elongation of the upper cover to rotate the lever in the first direction around the rotation shaft of the lever;
- and
- an elastic body configured to rotate the lever in a second direction.
