Vibration energy harvesting is a technology that aims to collect unused or wasted mechanical energy from the environment and convert it to electric energy. It has attracted increasing attention in the last decade as a local and decentralized power source for embedded systems. In this research, a novel class of wide-band and high-power-efficiency energy harvesting devices is realized by combining a nonlinear hardening oscillator such as impact oscillator and bistable oscillator with a self-excitation circuit. As a consequence, the power-bandwidth trade-off, one of the most significant problems that impede the practical use of the vibration harvesting devices, has been resolved for the case of the periodic excitation. Furthermore, a new idea which can lead to high power regeneration from a low frequency vibration source has been suggested by pursuing the improvement of the power conversion efficiency from the mechanical input energy to the retrieved electric energy.

振动能量收集是一项旨在从环境中收集未使用或浪费的机械能并将其转化为电能的技术。在过去的十年里，它作为嵌入式系统的本地和分散式电源越来越引起人们的关注。本研究将冲击振荡器、双稳振荡器等非线性硬化振荡器与自激电路相结合，实现了一种新型的宽带高能效能量采集装置。因此，对于周期性激励的情况，解决了阻碍振动采集装置实际应用的最重要的问题之一--功率带宽权衡。此外，还提出了从机械输入能量到回收电能的能量转换效率的提高，从而实现低频振动源高功率再生的新思路。
