“…Both theoretical and experimental results indicate that, by adjusting the electrical components in the circuit, the transducer can be tuned to (or close to) a resonant state. Prospective research on boosting the mechanical-to-electric efficiency may involve nonlinear treatments of electric circuits by using, for example, SCE (synchronized charge extraction) [295][296][297] and SSHI (synchronized switch harvesting on inductor) [298] techniques.…”

“…Although the traditional linear energy harvesting model was feasible for energy harvesting circuits in some cases, the corresponding system required more power consumption than the nonlinear energy harvesting model [245]. NES could improve the energy harvesting frequency bandwidth of an energy harvesting system based on a synchronous charge extraction [115]. NES can provide a new way to power wireless sensors.…”

Vibration control has been of great interest to scientists and engineers for many years. Although linear vibration absorbers have been shown to be effective in mitigating vibrations at specific frequencies, their vibration reduction effect is usually limited to a narrow frequency bandwidth. Nonlinear energy sinks have attracted attention due to their better vibration reduction effect over a wider frequency bandwidth. In practical applications, the nonlinear energy sink devices can effectively absorb, dissipate, and convert energy from broadband excitation, so as to achieve vibration reduction and energy harvesting. However, research on energy harvesting based on the nonlinear energy sink is less mature than in linear systems. Multiple parameters of device design (e.g., damping size) affect the actual performance of the nonlinear energy sinks, but there is no exact method to simplify the design of the multiparameter nonlinear energy sinks. Since it is more difficult to implement electromagnetic and electrostatic energy harvesters, more research has focused on piezoelectric energy harvesters. This paper summarizes the research on the nonlinear energy sink and energy harvesting technology, including the introduction of the nonlinear energy sink, energy harvesting based on the nonlinear energy sink, and its application in various fields of energy harvesting. The paper also summarizes some important methods for solving the dynamical equations, as well as their advantages and disadvantages. The conclusions provide an outlook on the subsequent research of the nonlinear energy sink technology, such as the introduction of piezoelectric materials with high energy density, the benefits of balanced vibration suppression and harvesting of vibration energy, and the self-tuning of parameters in complex environments. It provides a powerful reference for the popularization and application of energy harvesting technology based on nonlinear energy sinks.

“…These include (a) the tunable SECE [54], N-SECE [55] and SECPE (synchronous electric charge partial extraction) proposed for highly coupled piezoelectric energy scavengers [56]; (b) the PS-SECE (phaseshifted SECE) [57] and FT-SECE (frequency-tuning SECE) proposed for bandwidth improvement; [58] (c) the C-SP-SECE (compact self-powered SECE) [59,60] and SP-ESECE (self-powered efficient SECE) [61] proposed for ameliorating the self-powered circuit performance; (d) the combination of SECE and the synchronized voltage inversion for power enhancement [62][63][64].

“…The resonant frequency of each cantilever bimorph is tuned by various magnitudes of proof mass bounded to its free end. The equivalent parameters of each cantilever bimorph are identified by the conventional modal testing[76] and are listed in table 1. In the table, the short circuit and open circuit resonant frequencies of each oscillator are denoted by f sc and f oc , respectively.…”

The paper studies the electrical response of an array of piezoelectric oscillators attached to the synchronized electric charge extraction (SECE) interface circuit. The analytic estimate of output power is derived and presented through the matrix formulation of generalized Ohm’s law (charging on capacitance) for the case of parallel (series) connection of energy harvesters. These formulations mainly depend on the proposed equivalent load impedances which are independent of external resistive loads. It therefore offers an advantage of enabling harvested power independent of DC output voltage and making the harvester array desirable for broadband energy scavenging. The proposed framework is subsequently validated both numerically and experimentally. The results show that the power output and bandwidth of an SECE-based array are superior to that based on the standard energy harvesting circuit. Further, it is found that the behavior of an SECE array electrically arranged in parallel connection is different from that connected in series. The former demonstrates the output power higher than the latter, while the latter exhibits roughly uniform peak power in frequency response. However, the experiment indicates the unexpected power drop deviated significantly from the prediction in the array of harvesters connected in series. Such a discrepancy is explained as a result of comparatively serious leakage current in the reverse-biased diodes.
