According to an embodiment, disclosed is an energy harvester which generates energy by a magnet part which bounces back up like a roly poly due to an external vibration. The center of gravity of the magnet part is located under a geometric center and bounces back up around a vertical axis. The energy harvester may include a housing having an interior space, a magnet part, and a harvester part. The magnet part is arranged in the housing and may include a permanent magnet. The mass of the lower part of the magnet is greater than that of the upper part. The harvester is formed in the outside of the housing and can generate power due to the change of the magnetic force of the magnet part. The magnet part bounces back due to the external vibration of the housing, thereby generating power in the harvest prat. |
