“…Numerous implementations of multi-frequency energy harvesters are proposed till now. For example multi-frequency energy harvesters with double mass (Qu and et al 2011),fractal-inspired (Castagnetti, 2016), two degree of freedom (2-DOF) (Wu and et al 2012) or multiple degree of DOF (Xiao and et al 2016), zigzag shaped (Lee and et al 2018;Zhou and et al 2017b) and etc. Extensive investigations and reported results shows that multi-frequency energy harvesters have huge potential.…”

“…There is also an ongoing investigation into various structural configurations and excitation mechanisms to realize an optimum (nonlinear) harvester. Leadenham and Erturk [21] presented an M-shaped oscillator for broadband energy harvesting and Lee et al [23] introduced a zigzag shaped torsional energy harvester. Benefiting from the asymmetric nonlinear behaviour of the harvester, a broadband behaviour was demonstrated under various excitation levels.…”

A nonlinear micro piezoelectric-electrostatic energy harvester is designed and studied using mathematical and computational methods. The system consists of a cantilever beam substrate, a bimorph piezoelectric transducer, a pair of tuning parallel-plate capacitors, and a tip-mass. The governing nonlinear mathematical model of the electro-mechanical system including nonlinear material and quadratic air-damping is derived for the series connection of the piezoelectric layers. The static and modal frequency curves are computed to optimize the operating point, and a parametric study is performed using numerical methods. A bias DC voltage is used to adapt the system to resonate with respect to the frequency of external vibration. Furthermore, to improve the bandwidth and performance of the harvester (and achieve a high level of harvested power without sacrificing the bandwidth) a nonlinear feedback loop is integrated into the design.

“…In contrast with the finite element model of [16] which require numerical code development, some efforts have been made to utilise commercial FEM and computational fluid dynamic (CFD) software for the energy harvesting simulation such as presented in [19][20][21][22][23]. Those models have been experimentally well validated, however, the analyses were only performed for short-circuit (no resistance load, R → 0) or opencircuit (R →∞) problems.…”

In this paper, a novel iterative finite element method (FEM) for energy harvesting purpose is presented. The new iterative FEM is implemented to solve the dynamic problems of piezoelectric-based energy harvester in the frequency and time domains. The validation against other methods from the literature shows the robustness and capabilities of the iterative FEM. Implementation to a transport aircraft wingbox with 14.5 m half span and an embedded piezoelectric layer is shown in some details. The energy harvesting potential of the wingbox due to the cruise and the 1-cosine gust loads is investigated. In addition, for the first time, stress and failure analyses of the structure with an active energy harvesting layer are performed. The results pointed out that the wingbox is still in a safe condition even when it is subjected to a 30 m/s gust amplitude while harvesting 51 kW power.
