With the remarkable increase in the number of mobile IoT devices, there is a growing demand for reliable and environmentally friendly power solutions to ensure their sustainable operation. As a result, the development of novel energy harvesting techniques has become increasingly urgent. Among them, flow-induced vibration energy harvesting, as a renewable and clean energy technology, is not only considered to play a crucial role in the decarbonization process of future energy systems but also has the potential to meet the energy needs of the increasingly popular mobile IoT devices for continuous and reliable operation.
Recently, Professor Wan Sun from Jiangsu University and his colleagues published a review article titled "Navigating the future of flow-induced vibration-based piezoelectric energy harvesting" in the top-tier energy journal Renewable and Sustainable Energy Reviews (IF=15.9). The paper explores the development of piezoelectric technology and materials, providing a comprehensive overview of the mechanisms, modeling techniques, and current development status of flow-induced vibration energy harvesters. Furthermore, it discusses various methods to improve the efficiency of piezoelectric energy harvesters, including optimizing structural configurations, adding nonlinear forces, applying multi-stable states, changing degrees of freedom, and optimizing interface circuits.Additionally, the article outlines several forward-looking areas for future research, including the utilization of metamaterials, integration of deep learning, and potential directions for commercialization, such as the construction of bladeless wind farms and the design of robust and environmentally stable energy harvesters. This study offers valuable insights and guidance for the advancement of flow-induced vibration energy harvesting technology.
