Some Advances in the Theory of Dynamics of Bursting Oscillation Energy Harvesting
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 pro-vide 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-fre-quency 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 perform-ance in the environment with the low-frequency and slowly changing excitations. Therefore,it is neces-sary 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 oscilla-tion energy harvesting,and the efficiency of bursting oscillation energy harvesting. Finally,some sug-gestions for conducting research of bursting oscillation energy harvesting technologies are given.
