The fluid energy represented by water flow is the most widely distributed mechanical energy in nature.The design and efficiency enhancement methods of micro piezoelectric energy harvesters based on water induced vibration have received widespread attention from domestic and foreign researchers in recent years.Firstly,the classification and characteristics of water induced vibration energy harvesting devices were introduced,which can be divided into two categories based on their working mechanisms:blunt body induced cantilever beam type and wake induced type.Secondly,the efficiency enhancement methods of energy harvesting devices were reviewed,and representative structures and performance characteristics of nonlinear magnetic efficiency enhancement,hybrid and array efficiency enhancement were analyzed.Finally,the current problems and challenges in the field of fluid vibration hydrodynamic energy capture are summarized,and the prospects of future development are put forward.
