“…Yang and Cao 141 proposed a new tri-stable hybrid vibration energy harvester using a geometric nonlinear technique to tune the resonant frequency and widen the bandwidth, which was shown to have wider resonant bandwidth than monostable and bistable energy harvesters. Yang et al 142 presented a magnetically levitated hybrid energy harvester with tri-stable nonlinear behavior utilizing four external static magnets in the same plane. Theoretical and experimental studies demonstrate that the harvester has a frequency bandwidth of 3–8 Hz and output power of 6.9 and 6.44 mW in the horizontal and vertical directions, respectively, at 8 Hz frequency and 1 g acceleration.…”

Nowadays, with the rapid development of the intelligent era and the concept of Internet of Things being proposed, more and more sensors will play a more important role. Providing a sustainable power source for sensors has become the focus of current research in microsystem power generation. The harvesting of widely available vibrational energy from the environment for use as an alternative power source for sensors is of great significance in efficient energy utilization. Researchers have been working on developing efficient energy harvesters for broadband and efficient energy harvesting. Nonlinear energy harvesting holds more significant promise. In this paper, we summarized and reviewed the research progress of three different harvesting methods from the perspective of varying energy harvesting methods. We also listed the operation of various harvesters under different excitation types. At the same time, nonlinear energy harvesters with different structural characteristics are reviewed, the benefits of nonlinearity on energy harvesting are effectively collected, and the practical applications are summarized. Finally, current methods and mechanisms to improve the collection efficiency of energy harvesters are described and summarized. Briefly, this review introduces the research development of existing energy harvesting technologies, summarizes the technically difficult problems faced by piezoelectric energy harvesting technologies, and provides an outlook for future research and development trends of piezoelectric vibration energy harvesting technologies.

“…The researchers initially hoped to use EMG-TENG to generate electricity, which is the most direct application. Later, researchers developed more application scenarios, including powering small electronic devices, sensors, and wearable devices [106][107][108][109]. We will sum up the performance and application of EMG-TENG to clarify the application value of EMG-TENG in human life in this section.…”

Since the triboelectric nanogenerator (TENG) was invented, it has received extensive attention from researchers. Among the many pieces of research based on TENG, the research of hybridized generators is progressing rapidly. In recent years, the research and application of the electromagnetic–triboelectric hybridized nanogenerator (EMG-TENG) have made great progress. This review mainly focuses on the latest research development of EMG-TENG and elaborates on the principles, materials, structure, and applications of EMG-TENG. In this paper, the microscopic charge transfer mechanism of TENG is explained by the most primitive friction electrification phenomenon and electrostatic induction phenomenon. The commonly used materials for fabricating TENG and the selection and modification methods of the materials are introduced. According to the difference in structure, EMG-TENG is divided into two categories: vibratory EMG-TENG and rotating EMG-TENG. The summary explains the application of EMG-TENG, including the energy supply and self-powered system of small electronic devices, EMG-TENG as a sensor, and EMG-TENG in wearable devices. Finally, based on summarizing previous studies, the author puts forward new views on the development direction of EMG-TENG.

“…They have been widely tested, resulting in various proposed designs [ 7 , 8 , 26 , 27 , 41 , 42 , 43 ]. In addition, theoretical models and experimental investigations of a broadband piezoelectric-based vibration energy harvesters with tri-stable functions of potential barriers were proposed and developed [ 44 , 45 , 46 , 47 ]. To enhance the performance of the bistable and tri-stable energy harvesters, quad-stable and penta-stable energy harvesters were designed by adding more fixed magnets presented in [ 48 , 49 ] or with combined nonlinearity of cantilever-surface contact and magnetoelasticity [ 50 ].…”

The subject of the research contained in this paper is a new design solution for an energy harvesting system resulting from the combination of a quasi-zero-stiffness energy harvester and a two-stage flexible cantilever beam. Numerical tests were divided into two main parts-analysis of the dynamics of the system due to periodic, quasiperiodic, and chaotic solutions and the efficiency of energy generation. The results of numerical simulations were limited to zero initial conditions as they are the natural position of the static equilibrium. The article compares the energy efficiency for the selected range of the dimensionless excitation frequency. For this purpose, three cases of piezoelectric mounting were analyzed-only on the first stage of the beam, on the second and both stages. The analysis has been carried out with the use of diagrams showing difference of the effective values of the voltage induced on the piezoelectric electrodes. The results indicate that for effective energy harvesting, it is advisable to attach piezoelectric energy transducers to each step of the beam despite possible asynchronous vibrations.
