Vibration energy capture devices can convert the mechanical energy from ambient source into electrical energy. The captured electrical energy can provide energy for low-power devices such as microelectromechanical systems(MEMS) as a supplement to the power system. Vibration energy has been widely concerned by researchers because of the characteristics of easy access and green. The conversion of mechanical vibration energy into electrical energy can be achieved by electromagnetic, electrostatic, piezoelectric, magnetostrictive, dielectric elastomer and emerging friction nano-types. This paper have discussioned some parts of the vibration energy harvesting: collection principle, collection method and the energy storage circuit. At present, the research and design of mechanical vibration energy harvesting structures focus on three aspects: broadening the collection frequency band, collecting dimensions and improving efficiency. Finally, the future direction of energy harvesting research is predicted.
