“…To improve the aforementioned properties, research can be mainly classified into 1) tailoring the fluid force applied to the harvester and 2) optimizing the mechanical impedance of the harvester, which is dependent on the forcing frequency, mass, stiffness, and damping coefficient of the oscillating structure. [38] In terms of the fluid force, the force was typically tailored by changing the configuration of the object that couples with the water flow, e.g., the bluff body shape, [77,78] size, [45,49,79] number, [80][81][82] and arrangement. [80][81][82][83] In addition, the force applied to the harvester can also be tailored using magnets.…”

As a promising energy‐harvesting technique, an increasing number of researchers seek to exploit the piezoelectric effect to power electronic devices by harvesting the energy associated with water flow. In this emerging field, a variety of research themes attract interest for investigation; these include selection of the excitation mechanism, oscillation structure, piezoelectric material, power management interface circuit, and application. Since there has been no comprehensive review to date with respect to the harvesting of water flow using piezoelectric materials, herein relevant work in the last 25 years is reviewed. To ensure that key aspects of the water‐flow energy harvester are overviewed, they are discussed in the context of energy‐flow theory, which includes the three stages of energy extraction, energy conversion, and energy transfer. The development of each energy‐flow process is reviewed in detail and combined with meta‐analysis of the published literature. Correlations between the harvesting processes and their contribution to the overall energy‐harvesting performance are illustrated, and directions for future research are also proposed. In this review, a comprehensive understanding of water‐flow piezoelectric energy harvesting is provided and it is aimed to guide future research and the development of piezoelectric harvesters for water‐flow‐powered devices is promoted.

“…However, the VIV-based energy harvester (VIVEH) generally works well as the shedding frequency coincides with the natural frequency of structure. To extend the synchronization range and improve the VIV energy harvesting performance, plenty of studies including the optimization of bluff body [12][13][14][15][16][17][18][19][20], the introduction of non-linearity [21][22][23][24][25][26][27] and the interference effects of bluff bodies [28,29] have been conducted. Dai et al [12] investigated the orientation of bluff body so as to get the best performance of VIV energy harvesting.…”

To investigate the influence of bluff body with a variable section on the vortex-induced vibration energy harvesting performance, a series of hybrid cylinders are designed and a quantitative comparison is presented. The basic elements of hybrid bluff body are the D-shaped (D) and original circular-shaped cylinders (O), and the length ratio between the O-shaped part and the D-shaped part is fixed. According to the arrangement order, three kinds of hybrid bluff bodies are termed as ODO, ODODO and DOD. A distributed model is developed and the numerical simulation is carried out to verify the response. Corresponding wind tunnel experiments are conducted, and the results reveal that compared to the bluff body with a circular cylinder, the hybrid bluff bodies such as ODODO and DOD can enhance the vortex-induced vibration and thus increase the output significantly. Moreover, the lock-in regions with the ODODO and DOD shapes will increase by 12.5% and 62.5%, respectively. However, the results also indicate that some type of arrangement such as ODO will suppress the energy harvesting performance. Furthermore, the computational fluid dynamics (CFD) method is employed to reveal the physical mechanism of flow field around the hybrid bluff body. The results show that the integration of D-shape prism in a cylinder along an axial direction could influence aerodynamics. A faster boundary layer separation occurs for the VIV energy harvesters with the hybrid cylinders of ODODO and DOD, which could improve the energy conversion efficiency from flow-induced vibrations. However, the aerodynamic force is restricted and response is suppressed as a D-shaped cylinder is sandwiched between two O-shaped cylinders.

“…In contrast, piezoelectric ceramics are widely applied in highfrequency small deformation scenes because of their effective piezoelectric coefficient. It is worth noting that wind energy is abundant in nature, and researchers have developed numerous efficient piezoelectric energy harvesters (PEHs) with vortex-induced vibration (VIV) (Hu et al, 2018;Wang et al, 2021), galloping (Dash et al, 2020;Sun and Seok, 2021;Tan et al, 2021;Zhou et al, 2019), flutter (Eugeni et al, 2020;McCarthy et al, 2014), and wake-induced vibration (Xie et al, 2012;Zhao et al, 2021). The coupling between the airflow and bluff body produces unstable aerodynamic lift, which activates the deformation of the piezoelectric beam.…”

This paper presents a magnetically coupling bending-torsion piezoelectric energy harvester based on vortex-induced vibration from low-speed wind. The theoretical model of the energy harvester was formulated and validated by wind tunnel experiments. Numerical and experimental results showed that the power output and bandwidth of the proposed harvester are improved about 180% and 230% respectively compared with the nonmagnetic coupling harvester. Furthermore, the effects of cylinder, piezoelectric layer, load resistance, and magnetic nonlinear parameters on the harvester were investigated based on the distributed parameter model. The results showed that the length of cylinder hardly affect output power, but the diameter of cylinder presented complicated influences. The width of piezoelectric beam was negatively correlated with the torsion angle. With increasing the length of piezoelectric layer, an optimal wind velocity and load resistance can be obtained for the maximum output power. With decreasing of the distance between two magnets, the resonant bandwidth, the optimal power output, and torsion angle can be enhanced, respectively. Besides, the magnetic potential energy increased owing to the magnetically coupling, which led to the improvement of onset speed for the energy harvester. This study provides a guideline on improving the performance of bending-torsion vibration piezoelectric energy harvester.
