“…[31][32][33] In recent years, to overcome the problem of the narrow effective bandwidth of linear vibration energy harvesting, researchers have applied nonlinear structures to the field of vibration energy harvesting. [34][35][36] The application of nonlinear structure can increase the number of potential wells to achieve bistable, [37,38] tristable [39,40] and multistable characteristics. [41,42] These energy harvesters can move across potential wells at different equilibrium positions, thereby widening the frequency band.…”

Due to technical limitation, existed vibration isolation and vibration harvesting (VIEH) devices have poor performance at low frequency. Therefore, this paper proposes a new multi-link-spring mechanism (MLSM), which can be used to solve this problem. The VIEH performance of MLSM under harmonic excitation and Gaussian white noise are analyzed. It was found that the MLSM has well vibration isolation performance under low frequency isolation, and the frequency band can be widened by adjusting parameters to achieve higher energy harvesting power. By comparing with two special cases, the results show that the MLSM is basically the same as the other two oscillators in terms of vibration isolation but has better energy harvesting performance under the multi-stable characteristic. The MLSM is expected to reduce the impact of vibration on high-precision sensitive equipment in some special sites such as subway and mine, and at the same time supply power to structural health monitoring device.

“…The obtained results showed that the generated voltage and power level are amplified under the simultaneous effects of two strong excitations such as super-harmonic and harmonic resonances. Energy harvesting and Wideband vibration isolation based on a coupled piezoelectric-electromagnetic structure were investigated in Reference 30. Using energy harvesting to power marine environment monitoring was studied in Reference 31.…”

This article studies the motion of a three degrees-of-freedom (DOF) dynamical system, which consists of two parts, a dynamic part, and an electromagnetic harvesting device. The composition of the system depends on the magnet oscillating in the coil of this device. An electric potential is exerted because of the electromotive force to obtain energy harvesting (EH). Lagrange's equations (LE) are used to derive the system’s equations of motion (EOM), which are solved analytically up to a third-order of approximation using the multiple-scales method (MSM). These solutions are considered novel, in which the mentioned method is applied to a novel dynamical system. The gained are confirmed through comparison with the numerical solutions of the EOM to reveal a high degree of consistency. To establish the system’s solvable conditions and modulation equations (ME), three scenarios of primary external resonance are investigated simultaneously. Certain diagrams of time histories for the amplitudes and phases of the examined dynamical system are plotted to show their behaviors at any given instance of time. The Routh–Hurwitz criteria (RHC) are used to establish the stability and instability regions in light of the graphs of resonance response curves. The presence of an energy harvester in dynamic devices helps us to convert vibrational motion into electrical energy that can be exploited in several applications in a variety of daily tasks, including structural and environmental monitoring, military applications, space exploration, and remote medical sensing.

“…However, these electronic devices rely on battery power which largely limits the rapid development of them (Zhang et al, 2021a). Therefore, finding a new source of energy to power wearable electronic devices and reduce their dependence on batteries is an urgent problem to be solved (Fang et al, 2023a; Van et al, 2021). To solve the problem of continuous power supply, scholars have studied various methods of energy harvesting, such as vibration energy in the environment (Ma and Zhou, 2022; Shan et al, 2019b; Zhou et al, 2022), wind energy (Kumar Rasappan et al, 2022; Lai et al, 2023; Li et al, 2022), solar energy (Tong et al, 2022; Yang et al, 2022; Zhang et al, 2022c), etc.…”

To better harvest the kinetic energy of the human and broaden the energy harvest frequency band, a nonlinear piezo-electromagnetic composite human energy harvester (NPE-HEH) is proposed. A magnetic repulsion force between the two groups of magnets makes the energy harvester nonlinear. The excitation experiment and the actual experiment of the human are carried out for the harvester. The excitation experiment results show that there is an optimal resistance value of the harvester to maximize the output power value. When the excitation acceleration is 0.4 g and the excitation frequency is 9 Hz, the output voltage value and the output power of the electromagnetic part of the energy harvester are 0.86 V and 2.47 mW respectively, and the output performance is excellent. When the energy harvester is installed in a backpack with a moving speed of 9 km/h, it can generate 0.7 mW of power. When the energy harvester is placed on the leg, the output performance is good and the output power can reach 1.3 mW. The energy harvester can efficiently harvest energy at low frequencies. This harvester is efficient at low frequencies, compact in size, and easy to carry, making it highly suitable for human vibration energy harvesting applications.
