英文摘要：

With gradually expansion of the application field for micro-nano devices,micro energy technology have been paying more and more concerns and attentions by domestic and oversea researchers,among which micro fluid energy harvester based on the vortex-induced vibration（VIFEH）has become a hotspot.First,the operational principle of the VIFEH was introduced and the typical structure,theory,features and application situation of VIFEH were generalized.Then,the relative technology development and research progress of the fluid energy harvester with wake-induced vibration and that with vibrational bluff body were summarized and the research status of fluid solid coupling mathematical model for VIFEH was briefly described.The analysis results show that VIFEH still lack the uniform mathematical model and there are low reliability and comparably low stability in the existing VIFEH structure.Moreover,further development trend of VIFEH was pointed out.It is expected to promote the research and applications of VIFEH through this work.
