“…However, LEH can only perform efficiently in a narrow range near its natural frequency. To deal with this issue, different ways have been developed to broaden its bandwidth, including but not limited to active or passive frequencytuning methods [11,12] and nonlinear methods that were monostable [13,14], bi-stable [15][16][17][18][19][20] and multi-stable [21][22][23][24][25]. Among these methods, nonlinear methods capture much interest because of their abilities to expand bandwidth to lower frequencies.…”

To enhance the harvesting performance of a bi-stable piezoelectric energy harvester (BEH), this work proposes a four-magnet BEH (FBEH). FBEH consists of a piezoelectric cantilever beam with a tip magnet, a fixed magnet and two movable magnets. The two movable magnets relative to the fixed magnet can move in both horizontal and vertical directions. A nonlinear distributed parameter model of FBEH is derived through the Hamilton principle. The effects of the excitation frequency and amplitude as well as the horizontal and vertical gap on the harvesting performance are mainly investigated by using the bifurcation diagram, phase diagram, Poincaré map and output power. Numerical simulations demonstrate that the proposed FBEH decreases the potential barrier and creates a higher than typical bi-stable one when subjected to lower excitation amplitudes and frequencies.

“…Mann and Owens [22] investigated the presence of co-existing solutions and a broadening in the frequency response for some levels of base excitation. While Tan et al [32] indicated an optimal performance analyzing the coefficients of the linear and cubic elastic external forces. The response to different forms of excitation is studied in [16], in particular, harmonic noise and stochastic white noise.…”

“…Because of its simple structure, piezoelectric energy harvester was extensively studied in past decades [15,16]. In addition, the analytical solution of the electromechanical coupling of the piezoelectric energy harvester is also studied [17,18]. According to the difference of the used piezoelectric material, the piezoelectric energy harvesters usually can be divided into two categories based on piezoelectric patch [19,20] or piezoelectric stack [21,22], which harvest the mechanical energy using the d 31 and d 33 effects, respectively.…”

In recent years, the use of wearable and portable electronic devices has steadily increased. These devices are becoming more and more powerful. However, advances in device performance have resulted in the need for significantly higher power to operate electronic devices. The power supply problem of these electronic devices has become one of the factors hindering their development. In order to solve the power supply problem of these electronic devices, researchers have begun to study methods of generating energy from the ambient sources. This study presents the design, modeling and experimental tests of a novel piezoelectric energy harvester with the reverse-rhombus double-bridge force amplification frame, which can harvest energy from human motion. The double-bridge structure of the energy harvester can effectively amplify the force acting on the piezoelectric stack and improve the output performance of the energy harvester. A lumped parameter model for the vibration energy harvester based on the piezoelectric stack is presented and the analytical formulations for the electromechanical coupling are derived. The non-linear model is simulated to study the effects of the parameters, such as preload, external excitation frequency and load resistance, on the output performance. The prototype of the vibration energy harvester based on piezoelectric stack was fabricated. The shaker experiment and the backpack energy harvesting experiment were performed. The theoretical model is validated through comparisons with simulation and experimental results. The piezoelectric energy harvester developed in this paper can be used to harvest the mechanical energy of the human motion, as well as the vibration energy of the surrounding environment. The presented theoretical model can be utilized to model other types of piezoelectric energy harvester and predict their output performance.
