In our daily life environment, there are a lot of micro energy such as vibration, low thermal energy. In the past due to the limitations of technical capabilities, this micro energy has not been effectively collected and utilized. With people's increasing attention to the effective use of energy and environmental protection, this clean, renewable micro energy have become the focus of research in related fields. In this paper, by means of the research of electromagnetic vibration acquisition system at home and abroad, the working principle of the electromagnetic vibration collector is clarified. On this basis, the micro vibration energy acquisition system is designed and realized, and we also put forward some methods for improving the conversion efficiency of the circuit system. Finally, the feasibility and effectiveness of the system are verified by several experiments at the end.
