Recent advancement of flow-induced piezoelectric vibration energy harvesting techniques: principles, structures, and nonlinear designs

Abstract

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.

Development and Prospect of Smart Materials and Structures for Aerospace Sensing Systems and Applications

“…In order to study the collection of vibration energy by piezoelectric energy harvesters, generally attention is paid to the energy escape forms, such as galloping, vortex-excited vibration, and flutter generated by the excitation of beams, cylinders, plates, and other structures under the excitation of air flow in aerospace [ 25 , 26 ]. In contrast, airfoil flutter has attracted more attention from researchers, but there are a large number of nonlinear factors in the complex aviation structure, and the actual behavior often shows complex dynamic behavior, so it is necessary to conduct in-depth research and reliability verification of the relevant models to ensure the safety of the aircraft [ 27 ].…”

“…These vibration sources are not affected substantially by environmental and climatic factors and produce relatively stable energy. Vibration-based energy harvesting is one of the power supply technologies with various potential applications [1][2][3]. Based on the piezoelectric effect, many kinds of mechanical oscillating systems have been designed to improve the energy conversion efficiency, such as multi-stable models, nonlinear internal resonant models, impact up-frequency models and mechanical amplifying mechanisms [4][5][6][7][8].…”

“…Vibration, as a source of renewable energy, is abundant in nature. Vibration energy harvesting, a conversion procedure from low-quality and high-entropy vibration energy to the electricity, has attracted attention around the world [1][2][3] . A host of previous research works focused on the scheme of linear resonance.…”
