Perspectives in flow-induced vibration energy harvesting

Flow-induced vibration (FIV) energy harvesting has attracted extensive research interest in the past two decades. Remarkable achievements and contributions from different aspects are briefly overviewed. Example applications of FIV techniques development Internet Things mentioned. The challenges difficulties this field summarized sides. First, multi-physics coupling problem still cannot be well handled. There is a lack system-level theoretical modeling that can accurately account for fluid–structure interaction, electromechanical coupling, complicated interface circuits. Second, robustness harvesters needs to further improved adapt uncertainties practical scenarios. To more specific, cut-in wind speed expected reduced power output increased. Finally, Perspectives on future direction discussed. Machine-learning approaches, versatility metamaterials, advanced circuits should receive attention researchers, since these cutting-edge may have potential address significantly improve operation performance. In addition, in-depth collaborations between researchers disciplines anticipated promote technology step out lab into real applications.
