A review on vibration energy harvesting

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