Abstract: With the progress of MEMS technology, it is possible to power the sensor system by means of the electricity produced by the vibration energy harvester. The vibration energy harvesting technology based on environment vibration has become a hot topic for the study of nonlinear dynamics. The bistable electromagnetic vibration energy harvester with an auxiliary linear oscillator was studied. The dynamic equations under colored noise were established. The dynamic characteristics of the bistable vibration energy harvester excited by colored noise were studied through numeric simulation for varying parameters including the noise intensity, the mass ratio and the tuning ratio. The influencing law of the noise intensity, the mass ratio and the tuning ratio was obtained. The research results provide a theoretical basis for the further study of bistable electromagnetic vibration energy harvesters.
