Model and Experimental Study of Permanent Magnet Vibration-to-Electrical Power Generator

The vibration energy exists widely and is always wasted. Energy harvesting devices that convert kinetic energy into electrical energy have attracted much interest. A variety of vibration driven generators using electromagnetic principles to convert the kinetic energy into electrical energy, are being studied for powering sensors. However, the power supply is always a bottleneck problem to the development of handheld electronic equipments and some other low power electrical apparatus.
