“…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 ].…”

“…It is worth noticing that the limit of increasing multistability naturally leads to decreasing the individual potential barriers. In that context, the quasi-zero stiffness case is a simplified realization of multiple equilibria coming from the flattened series of many potential wells [ 48 , 49 ] or case-characterized by the potential at the bifurcation point between monostable and bistable potentials [ 51 ] with respect to the control parameter. Such a solution was also proposed and proven to be useful for energy harvesting [ 52 , 53 ].…”

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.

“…Numerical simulations of the developed mechanical model are performed to analyze the effects of different magnetic spacing on the power generation performance and dynamic response, and this study makes a theoretical contribution to the use of piezoelectric energy harvesters in wake dancing situations. Qian et al 137 developed a quadratic steady-state energy harvester whose equilibrium coordinates can be defined by the user like programing and can be customized for different vibration environments. It is capable of outputting a peak power of 575 μW at an excitation acceleration of 2 m/s 2 and 8.5 Hz.…”

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 most popular application is the conversion of mechanical energy into electrical energy, widely developed in the scientific literature [ 8 , 11 ]. Such systems are usually based on a flexible cantilever beam [ 12 , 13 ] with a piezoelectric transducer attached to it. Vibrations of the forcing object cause variable deformations of the beam and the transducer itself, and this allows generation of electricity.…”

The basic types of multi-stable energy harvesters are bistable energy harvesting systems (BEH) and tristable energy harvesting systems (TEH). The present investigations focus on the analysis of BEH and TEH systems, where the corresponding depth of the potential well and the width of their characteristics are the same. The efficiency of energy harvesting for TEH and BEH systems assuming similar potential parameters is provided. Providing such parameters allows for reliable formulation of conclusions about the efficiency in both types of systems. These energy harvesting systems are based on permanent magnets and a cantilever beam designed to obtain energy from vibrations. Starting from the bond graphs, we derived the nonlinear equations of motion. Then, we followed the bifurcations along the increasing frequency for both configurations. To identify the character of particular solutions, we estimated their corresponding phase portraits, Poincare sections, and Lyapunov exponents. The selected solutions are associated with their voltage output. The results in this numerical study clearly show that the bistable potential is more efficient for energy harvesting provided the corresponding excitation amplitude is large enough. However, the tristable potential could work better in the limits of low-level and low-frequency excitations.
