“…However, due to the barrier in the potential function, the large-amplitude interwell oscillation does not occur all the time, because the intensity of the vibration sources in nature is uncertain. To solve this problem, tristable [ 160 , 161 , 162 , 163 , 164 , 165 , 166 , 167 ], quadstable [ 168 , 169 , 170 , 171 ] and even pentastable [ 172 , 173 , 174 ] configurations were investigated recently. With more potential wells, the potential energy can be distributed more uniformly, and the barriers between the potential wells can be lower, even though the barriers between the potential wells still exist.…”

Piezoelectric vibration energy harvesting technologies have attracted a lot of attention in recent decades, and the harvesters have been applied successfully in various fields, such as buildings, biomechanical and human motions. One important challenge is that the narrow frequency bandwidth of linear energy harvesting is inadequate to adapt the ambient vibrations, which are often random and broadband. Therefore, researchers have concentrated on developing efficient energy harvesters to realize broadband energy harvesting and improve energy-harvesting efficiency. Particularly, among these approaches, different types of energy harvesters adopting magnetic force have been designed with nonlinear characteristics for effective energy harvesting. This paper aims to review the main piezoelectric vibration energy harvesting technologies with magnetic coupling, and determine the potential benefits of magnetic force on energy-harvesting techniques. They are classified into five categories according to their different structural characteristics: monostable, bistable, multistable, magnetic plucking, and hybrid piezoelectric–electromagnetic energy harvesters. The operating principles and representative designs of each type are provided. Finally, a summary of practical applications is also shown. This review contributes to the widespread understanding of the role of magnetic force on piezoelectric vibration energy harvesting. It also provides a meaningful perspective on designing piezoelectric harvesters for improving energy-harvesting efficiency.

“…Introduction of non-linearity to piezoelectric energy harvesters can provide solution for the main disadvantage of energy harvesters i. e. narrow effective frequency response characteristics. Moreover, it can be found investigations on tri-stable (Zhu and et al 2017), multi-stable (Harris and et al 2017), hybrid (Yang and Towfighian, 2017) employment of multiple non-linear techniques . Unfortunately, non-linarites can provide bandwidth of piezoelectric energy harvesters only from several hertz to ten of hertz (Elvin and Erturk, 2013).…”

“…In order to widen the bandwidth of the PEHs, several types of nonlinear systems have been proposed. Typical nonlinear PEHs depicted in the literatura are monostable or bistable piezoelectric buckled beams (Cottone et al, 2012; Liu et al, 2013, 2016, 2017; Qian et al, 2020), monostable and bistable piezomagnetoelastic systems (Erturk and Inman, 2011a; Paula et al, 2015; Sebald et al, 2011; Wang et al, 2018b), tristable piezomagnetoelastic systems (Haitao et al, 2015; Kim and Seok, 2015; Zhu et al, 2017), and nonsmooth systems with mechanical stoppers (Ai et al, 2019; Blystad and Halvorsen, 2011; Liu et al, 2012). Recent studies also show the development of quadstable and pentastable structures (Kim and Seok, 2014; Wang et al, 2018a; Zhou et al, 2017a, 2017b).…”

Piezoelectric materials exhibit electromechanical coupling properties and have been gained importance over the last few decades due to their broad range of applications. Vibration-based energy harvesting systems have been proposed using the direct piezoelectric effect by converting mechanical into electrical energy. Although the great relevance of these systems, performance enhancement strategies are essential to improve the applicability of these system and have been studied substantially. This work addresses a numerical investigation of the influence of cubic polynomial nonlinearities in energy harvesting systems considering a bistable structure subjected to harmonic excitation. A deep parametric analysis is carried out employing nonlinear dynamics tools. Results show complex dynamical behaviors associated with the trigger of inter-well motion. Electrical power output and efficiency are monitored in order to evaluate the configurations associated with best system performances.
