<p>A micro power generating device configured to be disposed on a medium structure always in a vibrating environment to provide low-power electric energy includes a case, a body, elastic members, at least a magnetic member, a coil, and a circuit board. The body is combined in the case and has a chamber. One elastic member is respectively disposed on a top side and a bottom side of the chamber. The magnetic member is slidably accommodated in the chamber and is moved back and forth in the chamber by elastic forces provided by the elastic members. The coil is wound around the body. When the magnetic member is moved back and forth in the chamber under the effects of vibrations and the elastic forces provided by the elastic members, the coil generates an induced current accordingly. The circuit board is electrically connected to the coil, and used for processing the induced current generated by the coil into a power supply for external use.</p> |
