Piezoelectric vibration energy harvesting technologies have attracted a lot of attention in recent decades, and the harvesters have been applied successfully in various fields, such as buildings, biomechanical and human motions. One important challenge is that the narrow frequency bandwidth of linear energy harvesting is inadequate to adapt the ambient vibrations, which are often random and broadband. Therefore, researchers have concentrated on developing efficient energy harvesters to realize broadband energy harvesting and improve energy-harvesting efficiency. Particularly, among these approaches, different types of energy harvesters adopting magnetic force have been designed with nonlinear characteristics for effective energy harvesting. This paper aims to review the main piezoelectric vibration energy harvesting technologies with magnetic coupling, and determine the potential benefits of magnetic force on energy-harvesting techniques. They are classified into five categories according to their different structural characteristics: monostable, bistable, multistable, magnetic plucking, and hybrid piezoelectric–electromagnetic energy harvesters. The operating principles and representative designs of each type are provided. Finally, a summary of practical applications is also shown. This review contributes to the widespread understanding of the role of magnetic force on piezoelectric vibration energy harvesting. It also provides a meaningful perspective on designing piezoelectric harvesters for improving energy-harvesting efficiency.

In this study, we introduced 1:1 internal resonance in a magnetically coupled 2-degree-of-freedom (2-DOF) galloping-based piezoelectric energy harvester to improve the energy harvesting efficiency. The governing equations for the proposed magnetically coupled aero-electro-mechanical system considering the effect of oscillating wake are established using the extended Hamilton principle, and the method of multiple scale is exploited to obtain approximate analytical solutions. Parameter sweeping numerical calculation is conducted to validate the analytical prediction through comparing with analytical solutions, and the results show a good matching between them. In addition, we investigated the systematic dynamic behaviors under a pure oscillating wake induced 1:1 internal response. Typical nonlinear characteristics such as jump, hysteresis, frequency synchronization under varying design parameters appear in the present system. Especially, cusp bifurcation and synchronization regime of oscillating wake coupled nonlinear oscillator in \(\eta - {\Theta _w}\) plane and \(\sigma - {\Theta _w}\) plan. With an adoption of magnetic force, chaos happens as the gap distance decreases smaller than 5 mm, and a frequency lock-in phenomenon can be strengthened through adjusting the magnet distance. In the perspective of output performance, both of the voltage and power output results shows that the exploiting of 1:1 internal resonance can significantly improve the output performance under a suitable magnet distance.

“…Zhou et al [31] derived the nonlinear response characteristics of the asymmetric tri-stable energy harvester to improve energy harvesting performance for more general applications. Wang et al [32] proved that the tri-stable energy harvester possesses a wider potential well width and a lower barrier height, which greatly extends the operating frequency band. The tri-stable configuration has been demonstrated to enable piezoelectric energy harvester to generate electricity in a wider frequency range, and improve energy harvesting efficiency [33][34][35].…”

To reveal the nonlinear mechanism of the tri-stable piezoelectric vibration energy harvester based on composite shape beam (TPEH-C) and its influence on the system response, the nonlinear restoring force and the nonlinear magnetic force are discussed and analyzed in this paper. The nonlinear magnetic model is acquired by using equivalent magnetizing current theory, and the nonlinear resilience model is obtained by fitting experimental data. The corresponding distributed parameter model based on generalized Hamiltonian variation principle has been established. Frequency response functions for the TPEH-C are derived according to harmonic balance expansion, and the influence of different magnet distances and different excitation accelerations on the response amplitude and bandwidth of the TPEH-C are investigated. More importantly, the correctness of the theoretical analysis is verified by experiments. The results reveal that the spectrum of composite beam shows hard characteristic and the depth of potential well is changed, which provides a new way to ameliorate the potential well of the TPEH-C. A suitable magnet distance enables the TPEH-C to improve the response amplitude and the effective frequency range. The results in this paper have a theoretical guiding significance for the optimal design and engineering application of the TPEH-C.
