The State-of-the-Art Brief Review on Piezoelectric Energy Harvesting from Flow-Induced Vibration

Flow-induced vibration (FIV) is concerned in a broad range of engineering applications due to its resultant fatigue damage structures. Nevertheless, such fluid-structure coupling process continuously extracts the kinetic energy from ambient fluid flow, presenting conversion potential mechanical electricity. As air and water flows are widely encountered nature, piezoelectric harvesters show advantages small-scale utilization self-powered instruments. This paper briefly reviewed way collection by various measures proposed literature, which enhance structural response hence improve harvesting efficiency. Methods as irregularity alteration cross-section bluff body, wake flow interference, modification rearrangement cantilever beams, introduction magnetic force discussed. Finally, some open questions suggestions for future investigation renewable mode.
