The development of wireless sensor networks require more stable energy supply, which goes beyond the limit of traditional batteries. MEMS-based energy-harvesting technology can convert the environmental vibration energy and transform to electricity, with long life-span and no need to replace frequently. As it realizes self-power and it is a promising solution for the energy supply
