Abstract

An energy harvester is provided. The energy harvester includes a housing, a permanent magnet that is disposed within the housing, and a mass body that has a relative position to the permanent magnet changed by a translational motion within the housing by vibration energy from the exterior and that is formed of a magnetic substance. Further, a piezoelectric body generates electricity while elastically supporting vibration with respect to the housing of the permanent magnet by the translational motion of the mass body and an induction coil is disposed within the housing to generate induction electricity based on the vibration of the permanent magnet.
