“…Due to the high energy density and reliability of piezoelectric materials, vibrating-type piezoelectric energy harvesters for wind energy capture have garnered widespread attention [22]. Based on the piezoelectric conversion method, four types of aerodynamic phenomena including galloping [23][24][25], vortexinduced vibration (VIV) [26][27][28][29], flutter [30][31][32], and wake galloping [33][34][35][36] are generally utilized to achieve the conversion of wind energy and structural kinetic energy. Among them, compared with galloping and flutter, VIV is relatively easy to be excited at low wind speed and can also avoid damage of the piezoelectric materials caused by large vibrations.…”

A novel energy harvester based on vortex-induced vibration (VIV) of the sphere and piezoelectric effect is proposed to efficiently gather wind energy from all horizontal directions. An elastically-supported foam sphere is vertically arranged and considerably oscillates in the cross-flow direction when the wind speed is in the lock-in region. A piezoelectric beam is attached to the supported sphere by a spring and deforms periodically around the original buckling state, thereby converting kinetic energy into electrical energy. Experimental studies are performed to assess the power output of the harvester when exposed to wind flows with varying directions and speeds. The omnidirectional wind flow is divided to 12 orientations with the interval angle of 30°, and the wind speeds range from 1.17 m/s to 7.87 m/s. The testing findings indicate that the harvester has excellent consistency in both lock-in region and average power for various wind azimuths. When the wind direction is changed from 0° to 360°, the peak average power changes from 179.8 μW to 247.5 μW, and the wind speed region where the sphere undergoes vibration changes from 2.58 m/s"~" 7.05 m/s to 2.58 m/s"~" 7.87 m/s. Following that, the effects of the length of the supporting spring and the diameter of the sphere on the output average power and lock-in region are investigated experimentally. Finally, a demonstration of powering a wireless sensing node is performed to show applications of the designed energy harvester in windy conditions.

“…Bibo and Daqaq [31] investigated a wind-vibration energy harvester, and the results indicated that the wind and flutter speed have significant effects on the device's output. Hou et al [32] achieved hybrid energy harvesting from concurrent vortex-induced vibration and base excitations. Under the combined excitation of vortexinduced and base excitations, the harvester acquired an operational bandfour times broader than that of the vortex-induced vibration alone.…”

In this work, for the wind energy and vibration energy in practical environment, a novel zigzag-shaped energy harvester is proposed to harvest them simultaneously. This harvester is constituted of an inclined beam and a horizontal beam with a bluff body fixed at the free end. The inclined beam is covered by a piezoelectric patch. The vibration induced by wind flow and base excitation could produce electric energy through the piezoelectric material and realize energy harvesting. Especially, the softening characteristic created by magnetic interaction can extend the working bandwidth. The dynamical coupling equations are derived, and corresponding simulations are carried out, the results show that the cubic bluff body can help increase the wind-induced energy harvesting. The responses obtained under the base excitation combined with wind flow demonstrate that the hybrid excitation can provide a significant enhancement to the non-resonance region. The related validation experiments are carried out. The experimental results have a good agreement with the numerical results. Compared with the conventional base excitation or wind flow excitation, the output power obtained under hybrid excitation increases 106% and 206% respectively.

“…The literature review shows that the main element of piezoelectric energy harvesters are often a cantilever beam with a bluff body in its tip. Therefore, the nonlinear effect due to middle layer stretching effect has been neglected in the previous works (Abdelkefi et al, 2012;Akaydin et al, 2010;Dai et al, 2016;Ewere and Wang, 2014;Gao et al, 2013;Hou et al, 2020Hou et al, , 2022Jia et al, 2018;Li et al, 2022aLi et al, , 2022bLi et al, , 2023Ma et al, 2023;Mehmood et al, 2013;Rezaei and Talebitooti, 2019;Seyed-Aghazadeh et al, 2020;Skop and Griffin, 1973;Sui et al, 2022;Sun et al, 2019;Wang et al, 2020;Yang and He, 2019;Zhang et al, 2022;Zhang and Wang, 2016;Zhao et al, 2012Zhao et al, , 2016Zhao et al, , 2019.…”

“…Ma et al indicated that the working wind speed range can be widened and adjusted using a magnetic-coupled tri-stable configuration (Ma et al, 2023). The harvester consists of two working units, a piezoelectric unit, and an electromagnetic unit under combined vortex-induced and base excitations has been investigated in Hou et al (2022). It has been shown that combination of the excitation improves the performances of the harvester.…”

This paper investigates the middle layer stretching effect on the dynamic behavior of an energy harvester clamped-clamped beam. Two foam cylinders that are attached together as a dumbbell are mounted on the middle part of the beam for vortex-induced vibrations. The piezoelectric patch collects the electrical energy produced by vortex induced vibration. In this analysis the coupled differential equations governing on the structure oscillation, harvested voltage and fluid lift force are established applying the Hamilton’s principle, Gauss law and wake oscillator model. The obtained differential equations are discretized using Galerkin method, and solved by both numerical and analytical perturbation methods. The results demonstrate that middle layer stretching effect has a significant effect on the lock-in domain, and the output electric voltage must be evaluated by considering this effect. It has been shown that for large values of cylinder diameter the difference between numerical and theoretical results increases due to increasing the middle layer stretching effect.
