“…Thus, the whole system including the MTS machine and the piezoelectric stack energy harvester can operate stably. According to the previous study [5,50], the large prestress can affect the piezoelectric constant of piezoelectric stack, and further affect the voltage outputs. Therefore, the small preload displacement/force value should be applied to reduce the influence of the prestress on the voltage outputs.…”

“…According to the previous study [50], the piezoelectric strain constant d 33 can be regarded as a function of prestress. For the different prestresses, corresponding d 33 can be measured using the refined resonance method, the static method and the low frequency dynamic method [5,50,51]. These measured d 33 can be directly substituted into the theoretical models Reproduced with permission from [49].…”

Piezoelectric stack energy harvesters, by virtue of the higher mechanical-to-electrical energy conversion capability in the d33 mode, have been used widely in various fields, such as railway system, roadway system, and human motion. Dynamic continuous models (DCMs) of piezoelectric stack energy harvesters can more accurately reflect the electromechanical behavior but are difficult to be established due to complex coupling between layers, particularly in the presence of arbitrary loads. The existing models often only considered harmonic excitations and often ignored electrodes and protective layers for simplicity. This paper proposed a comprehensive dynamic continuous model (DCM) of piezoelectric stack energy harvesters considering the electrodes and protective layers, which can be used to study the electromechanical performance of the energy harvester under both harmonic excitation and arbitrary excitation. Comparisons of the developed generic DCM with the analytical model (AM) based on piezoelasticity theory (a dynamic continuous model which only considers the harmonic excitation)and the simplified model (SM) (a static continuous model which ignores inertia force of piezoelectric stack) are presented, with good agreements. Furthermore, the experiment results of two shapes of piezoelectric stacks, including tube and circular, are used to further confirm the reliability of the proposed model. In addition, effects of the electrode and protective layers on the dynamic properties are analyzed and discussed.

“…[480] Rail vibration and wind energy caused by running trains can be used as power sources for trackside electronic devices. [481,482] Due to the uneven surface roughness of the track, the running train can cause the vertical vibration of the track, with amplitudes rang-ing from 1 to 12 mm and frequencies ranging from 1 Hz to 4 Hz.

With the rapid development of the Internet of Things (IoTs), numerous distributed wide‐area low‐power electronic devices have been utilized in various fields, such as wireless monitoring sensors and wearable electronics. Due to the dispersion and mobility of microelectronic devices, their energy supply faces serious challenges. The inconvenience and non‐environmental friendliness of using traditional centralized low entropy energy and chemical batteries to power distributed microelectronic devices are becoming increasingly prominent. Environmental energy harvesting technology with high entropy characteristics is considered an effective solution for low‐power electronic devices. This paper comprehensively reviews the recent progress in microelectronic technologies based on energy harvesting and signal sensing. First, state‐of‐the‐art micro‐power electronic devices in humans, animals, and the environment are introduced. Secondly, the available micro‐energy sources in the environmentare elaborated and summarized. Then, the principles and characteristics of ambient microenergy harvesting technologies based on different mechanisms are classified, summarized, and analyzed. In addition, this work comprehensively summarizes the applications of self‐powered micro‐electronics technology in 11 different fields, including human, animal, and environment. Finally, research challenges, technical difficulties, and research gaps in self‐powered microelectronics based on micro‐energy harvesting technology are discussed and summarized.

“…In particular, it is convenient to scavenge energy from track vibration since the track detection sensors are usually placed close to the track. Some scholars have proposed several novel track vibration energy harvesters to supply railway electrical devices [10][11][12]. The mechanical energy obtained from ambient sources can be subsequently converted to electrical energy utilizing transduction mechanisms, such as electrostatic [13], electromagnetic [14], triboelectric [15] and piezoelectric [16] technologies.…”

In this work, for the wind energy and vibration energy in practical environment, a novel zigzag-shaped energy harvester is proposed to harvest them simultaneously. This harvester is constituted of an inclined beam and a horizontal beam with a bluff body fixed at the free end. The inclined beam is covered by a piezoelectric patch. The vibration induced by wind flow and base excitation could produce electric energy through the piezoelectric material and realize energy harvesting. Especially, the softening characteristic created by magnetic interaction can extend the working bandwidth. The dynamical coupling equations are derived, and corresponding simulations are carried out, the results show that the cubic bluff body can help increase the wind-induced energy harvesting. The responses obtained under the base excitation combined with wind flow demonstrate that the hybrid excitation can provide a significant enhancement to the non-resonance region. The related validation experiments are carried out. The experimental results have a good agreement with the numerical results. Compared with the conventional base excitation or wind flow excitation, the output power obtained under hybrid excitation increases 106% and 206% respectively.
