摘　　要：将自然环境中的振动能,通过能量采集装置转化为电能,为低功耗的电子器件提供清洁可持续的能源,对推动无线传感电子技术的发展具有重要意义.当环境的振动频率远低于采集装置的固有频率时,传统振动能量采集技术的采集效率将会明显降低,无法匹配低频的环境激励,而基于低频激励的簇发振荡通常表现为激发态的大幅振荡与沉寂态的微幅振荡的组合,具有大幅运动的高能轨道,在低频慢变激励的环境下依然保持较为良好的采集性能.因此,开展适应低频激励环境的能量采集技术的研究是很有必要.本文系统地概述了簇发振荡能量采集器的机电耦合能量转换装置、簇发振荡能量采集的动力学机理、簇发振荡能量采集的效率三个方面的研究进展.最后,给出了开展簇发振荡能量采集技术研究的一些建议.It is of great significance to promote the development of wireless sensing electronic technology to convert vibration energy in natural environment into electric energy through energy harvesters to provide clean and sustainable energy for low-power electronic devices.When the vibration frequency of the environment is much lower than the natural frequency of energy harvesters,the capture efficiency of the traditional vibration energy harvesting will be significantly reduced,which cannot match the low-frequency environmental excitations.However,the bursting oscillation based on low-frequency excitations is usually the combination of large oscillation in the excited state and small oscillation in the quiescent state,and has a high-energy orbit with large movement,which still maintains good harvesting performance in the environment with the low-frequency and slowly changing excitations.Therefore,it is necessary to develop energy harvesting adapted to the environment with low-frequency excitations.This paper systematically summarizes the research progress in three aspects:the electromechanical coupling energy conversion devices of bursting oscillation energy harvesters,the dynamic mechanism of bursting oscillation energy harvesting,and the efficiency of bursting oscillation energy harvesting.Finally,some suggestions for conducting research of bursting oscillation energy harvesting technologies are given.
