摘　　要：随着压电俘能技术研究的深入,研究重点已从俘能器本身逐渐发展为耦合环境振动源的俘能系统研究,其中基于压电效应的流体俘能技术是一个重要研究方向。鉴于此,对其研究现状和发展趋势进行了分析总结,主要包括单一压电振子俘能(涡激振动式、尾流致振式、颤振式、驰振式、雨滴冲击式)和多压电阵子阵列式俘能等。总结发现:涡激振动式和尾流致振式俘能器适合于低速流体俘能;颤振式和驰振式适合于高速流体俘能;为了提高发电能力,高性能柔性压电材料、宽频带俘能和多俘能器阵列俘能是今后的主要发展趋势。With the development of piezoelectric energy harvestingtechnology,the research focus gradually develops from the energy harvester itself to the energy capture system of coupled environmental vibration sources,in which the fluid energy capture technology based on the piezoelectric effect is an important study direction.Here,the study status and development trend of piezoelectric energy harvesting(PEH)were reviewed and summarized including single piezoelectric vibrator energy harvesting,such as,vortex-induced vibration types,wake-induced ones,flutter and gallopingones andraindrop impact ones as well as multi-piezoelectric array energy capture,etc.It was found that the vortex-induced vibration type energy harvesters and wake-induced ones are suitable for energy harvesting from low-speed fluid,and flutter and gallopingones are suitable for energy harvestingfrom high-speed fluid;In order to improve power generation capacity,high performance flexiblepiezoelectric materials,broadfrequency band energy harvesting and multi-piezoelectric array energy capturearefuture main development tendencies.
