In this study, we proposed a new rotational multi-stable vibration energy harvesting system to harvest vibration energy using elastic spring and piezoelectric element. Theoretical studies such as the equation of dynamic motion of the proposed rotational multi-stable vibration model, the distribution characteristics of elastic potential energy, and the prediction of the periodic excitation frequency by the natural vibration mode measurement experiment will be conducted. Using the developed rotational multi-stable vibration energy harvesting experimental device, we investigated the amplitude increase effect due to the new stochastic resonance phenomenon that occurs in the proposed rotary multi-stable vibration system, and evaluated the performance of the multi-stable vibration energy harvesting.
