Experimental Study on Passive Self-Tuning Phenomenon of FPED with Proof Mass

Abstract

　In recent years, the world's energy consumption has been increasing year by year due to the world's population growth, industrialization, and economic development in emerging countries. However, while much of the world's energy supply depends on fossil energy, fossil fuels are said to be depleted in decades. Therefore, research on vibration energy harvesters is being conducted as one of the measures. Vibration energy harvesters can generate a large amount of power by resonating with a vibration source. Therefore, this study focuses on the passive self-tuning phenomenon. The purpose of this research is to examine whether passive self-tuning phenomenon is useful for broadening the resonance band of vibration energy harvesters.
