“…They are mainly manufactured in a multimode structure intended for harvesting the highest power level from Kinetic energy sources for wideband operations. Principally, a piezoelectric harvester converts the mechanical strain of the active materials to electrical energy and the extracted energy is relative to the strain amplitude of the structure [52][53]. On the other hand, an electromagnetic harvester applies the relative motion between an electrical circuit and a magnetic flux to induce electricity into the circuit.…”

Energy harvesting (EH), as an enabling technology of energy derivation from ambient sources, has attracted much research attention in wireless sensor network (WSN) context. The magnetic energy harvester (MEH) introduces ambient energy harvesters' most promising technological development. This paper presents a review and analysis of MEH applications in WSN like vehicular systems and technologies. The successful approaches are introduced and classified based on technical characteristics and working principles. The fundamentals of their operation are discussed in detail, and the power points of each method are reviewed. To select the optimal energy harvester, in this work a case study is provided for feeding navigational sensors mounted on a rotating wheel of vehicles. Finally, the performance of the developed MEH model is evaluated and discussed for harvesting energy at the rotating wheels of a ground vehicle. To offer electromagnetic field analysis of the studied MEH, the simulations are performed in Ansys Maxwell software for further harvested power evaluation.

“…Magnetic force is another nonlinear force that is used to widen the frequency band of VEH, Samuel C. Stanton et al [25] is one of the first research groups to propose nonlinear magnet VEH model which can accurately predict the motion characteristics and power generation performance of the magnet VEH, the numerical prediction and experimental verification results show that the traditional cantilever beam can realize the frequency broadening effectively after the introduction of magnetic force. On this basis, a variety of new structures using nonlinear magnetic force to achieve broadband energy harvesting have been proposed and studied, which greatly promoted the practical process of broadband capture energy of VEH [26][27][28][29][30][31][32]. In addition to the introduction of magnetic force to nonlinear broadening of the frequency band, some scholars can also realize the broadening of the frequency band by using variable mass to generate nonlinear dynamics.…”

Harvesting environmental vibrations to power electronic components is an essential approach for addressing the power supply challenge in MEMS. However, conventional vibration energy collection systems frequently suffer from limited frequency bandwidth and high-frequency deficiencies. This paper proposes a novel up-frequency structure for piezoelectric vibration energy harvesting (VEH) that relies on both nonlinear magnetic force and piecewise linear force. The proposed VEH's nonlinear dynamic characteristics are analyzed theoretically, and an experimental prototype machining and vibration test platform are constructed. Theoretical and experimental results are compared and analyzed by conducting basic experiments and key parameter optimization experiments. The research results demonstrate that the proposed VEH can efficiently harvest vibration energy in low-frequency and wide-band environments. Regarding the system parameters, higher vibration acceleration results in increased output voltage and wider working frequency bandwidth. Reducing the gap distance enhances piecewise linear vibration, which broadens the working frequency bandwidth. Furthermore, the proposed VEH's ability to harvest low-frequency vibrations can be enhanced by reducing the magnet distance, thereby reducing the linear resonance frequency of the system. The findings of this study offer valuable insights for advancing the engineering application of MEMS self-power supply technology.

“…If vibration energy harvesters have both broadband and multi-directional energy harvesting characteristics, they can harvest more vibration energy from the vibration environment [2]. Therefore, many researchers have carried out studies on multi-directional broadband vibration energy harvesters [3][4][5].…”

A three-dimensional (3D), multi-directional and multimodal broadband vibration energy harvester using L-shaped curved beams is proposed in this paper. The harvester is composed of an L-shaped cylindrical bending beam and a piezoelectric beam. The free ends of the L-shaped bending beam and the piezoelectric beam are respectively fixed with a magnet. These two beams are coupled by nonlinear magnetic force introduced by the two magnets. The results show that the prototype can collect 3D multi-directional broadband vibration energies and has three natural frequencies in 3D directions. Under 5 m/s2 acceleration, the prototype obtains 42.1V, 45.0V and 66.9V peak-peak voltages in the x-direction, y-direction and z-direction respectively, and the widest 3 DB bandwidths in this three directions reach up to 6.4Hz, 6.3Hz and 4.2Hz, respectively.
