Research and Development of Vibration Energy Harvesting Technology

With the rapid development of wireless communications technology and micro-electro-mechanical technology, the vibration energy harvesting technology is widely used in the power supplying of system equipment. Vibration energy harvesting technologies include electromagnetic, electrostatic, piezoelectric, magnetostrictive and composite types. The application of giant magnetostrictive materials in energy harvesting is the latest research hot spot. This paper presented an overview of the basic principles of these five types of vibration energy harvesting technology, and made a brief introduction of materials and structural forms of each of energy collection devices. Advantages and disadvantages of these five types of vibration energy harvesting technologies have been compared. The main domestic and foreign research results and research progress, as well as the difficulties and trends have been introduced systematically.
