“…Using the nonlinear tri-stability mechanism, although technically, we require designing a more complicated structure for energy harvesting, the formation of a shallower potential well in the dynamic system can favor the process of energy harvesting under low-threshold excitation levels. Besides, Qin et al [97] , Wang et al [98] , and Zhou et al [99] have also reported several works on the design Fig. 12 Tri-stable galloping-based energy harvester [96] : (a) system design, (b) fitting curve of restoring force, and (c) potential energy function (color online)…”

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.

To improve the response-ability of the energy harvester to multidirectional wind, this paper proposes a wind energy harvester to scavenge wind-induced vibration energy. The harvester comprises a cylindrical beam instead of conventional thin rectangular cantilevers, a bluff body (square prism or circle cylinder), and a piezoelectric tube bonded to the bottom side of the beam for energy conversion. Benefiting from the symmetry of the cylindrical structure, this harvester can respond to airflow from every direction of the two-dimensional plane. The performance of the harvester under a wind speed range of 1.5–8 m/s has been tested. The results demonstrate that the proposed harvester can respond to the wind from all directions of the two-dimensional plane. It provides a direction for the future in-depth study of multidirectional wind energy harvesting.

Vibration response and performance of a piezoelectric energy harvester under the hybrid excitation of base vibration and galloping is studied. Based on the Euler-Bernoulli beam theory, the distributed-parameter model of a piezoelectric cantilever beam with base and galloping hybrid excitation is derived. Subsequently, the electromechanical coupled reduced order model and the decoupling model of the system is obtained. Thereafter, the analytical solution of the vibration response and the coupling relationship between the two hybrid excitations are analyzed. In the end, the impacts of the load resistance, the excitation acceleration and the wind speed on the power generation performance of the system are examined. Results indicated that the hybrid excitation can not only increase the energy harvester power of the system by 2.4W, but also effectively broaden the frequency band compared with the single foundation excitation. The research result is helpful to the dynamic design of a piezoelectric vibration energy harvesters under hybrid vibration excitation.
