PURPOSE: An energy harvester is provided to improve energy conversion efficiency in a low frequency range by including a fixed magnet part and a moving magnet part. CONSTITUTION: An energy harvester(100) converts vibration energy into electrical energy. Fixed magnet parts(120,125) are installed on the upper end and the lower end of a housing part(110). A moving magnet part(130) is located between the fixed magnet parts of the upper end and the lower end of the housing part. A coil part(140) is located near the moving magnet part. The coil part winds the housing part. |
