with environmental energy With the development of collection technology, wind energy is a kind of abundant clean energy! Its collection and utilization has gradually become a hot spot in the field of energy collection. Piezoelectric wind energy harvester based on flutter is one of the important research directions at present. And it has great application prospects in the self-supply of low-power devices. The research progress of flutter piezoelectric wind energy harvesters with different structures is introduced. Including conventional thin plate structure, airfoil structure and flag structure wind energy harvester; analyzed the characteristics and performance of various harvesters, and then summarized the current research progress of flutter wind energy harvester in terms of performance improvement, including piezoelectric electromagnetic Coupling#Bending plate type and array type three ways; Finally, the development trend of flutter piezoelectric wind energy harvester is prospected.
Keywords: energy harvesting; flutter; wind; piezoelectric
