Energy　harvesting　induced　from　flowing　fluids　(e.g.,　air　and　water　flows)　is　a　well-known　process,　which　can　be　regarded　as　a　sustainable　and　renewable　energy　source.　In　addition　to　traditional　high-efficiency　devices　(e.g.,　turbines　and　watermills),　the　micro-power　extracting　technologies　based　on　the　flow-induced　vibration　(FIV)　effect　have　sparked　great　concerns　by　virtue　of　their　prospective　applications　as　a　self-power　source　for　the　microelectronic　devices　in　recent　years.　This　article　aims　to　conduct　a　comprehensive　review　for　the　FIV　working　principle　and　their　potential　applications　for　energy　harvesting.　First,　various　classifications　of　the　FIV　effect　for　energy　harvesting　are　briefly　introduced,　such　as　vortex-induced　vibration　(VIV),　galloping,　flutter,　and　wake-induced　vibration　(WIV).　Next,　the　development　of　FIV　energy　harvesting　techniques　is　reviewed　to　discuss　the　research　works　in　the　past　three　years.　The　application　of　hybrid　FIV　energy　harvesting　techniques　that　can　enhance　the　harvesting　performance　is　also　presented.　Furthermore,　the　nonlinear　designs　of　FIV-based　energy　harvesters　are　reported　in　this　study,　e.g.,　multi-stability　and　limit-cycle　oscillation　(LCO)　phenomena.　Moreover,　advanced　FIV-based　energy　harvesting　studies　for　fluid　engineering　applications　are　briefly　mentioned.　Finally,　conclusions　and　future　outlook　are　summarized.
