“…In addition, the internal impedance of the PEH can be reduced. Woo et al [79] fabricated multilayer piezoelectric thick films by using the tape-casting process. By using an impedance analyzer, the capacitance of the five-layer device was measured to be 241.04 nF, which was 32.88 times higher than that of the single-layer device.…”

Piezoelectric energy harvester (PEH) is emerging as a novel device which can convert mechanical energy into electrical energy. It is mainly used to collect ambient vibration energy to power sensors, chips and some other small applications. This paper first introduces the working principle of PEH. Then, the paper elaborates the research progress of PEH from three aspects: piezoelectric materials, piezoelectric modes and energy harvester structures. Piezoelectric material is the core of the PEH. The piezoelectric and mechanical properties of piezoelectric material determine its application in energy harvesting. There are three piezoelectric modes, d 31 , d 33 and d 15 , the choice of which influences the maximum output voltage and power. Matching the external excitation frequency maximizes the conversion efficiency of the energy harvester. There are three approaches proposed in this paper to optimize the PEH's structure and match the external excitation frequency, i.e., adjusting the resonant frequency, frequency up-converting and broadening the frequency bandwidth. In addition, harvesting maximum output power from the PEH requires impedance matching. Finally, this paper analyzes the above content and predicts PEH's future development direction.

“…We performed the estimated calculations of the parameters of the proposed structure and obtained the distribution of the electric potential in the piezoelectric transducer, which consisted of 100 hybrid carbon nanostructures. Figure 14 shows the calculated electrical potential distribution at mechanical stress of 1 N. The generated voltage of the proposed piezoelectric transducer based on hybrid carbon nanostructures was at the level of modern transducers presented in the literature [46][47][48][49][50][51][52]. The active layers based on the hybrid carbon nanostructures make it possible to increase the generated voltage by a factor of 10 in comparison with a LiNbO3-based converter [52].…”

This paper reports the results of the influence of the energy of laser pulses during laser ablation on the morphology and electro-physical properties of LiNbO3 nanocrystalline films. It is found that increasing laser pulse energy from 180 to 220 mJ results in the concentration of charge carriers in LiNbO3 films decreasing from 8.6 × 1015 to 1.0 × 1013 cm−3, with the mobility of charge carriers increasing from 0.43 to 17.4 cm2/(V·s). In addition, experimental studies of sublayer material effects on the geometric parameters of carbon nanotubes (CNTs) are performed. It is found that the material of the lower electrode has a significant effect on the formation of CNTs. CNTs obtained at the same growth time on a sample with a Cr sublayer have a smaller diameter and a longer length compared to samples with a V sublayer. Based on the obtained results, the architecture of the energy nanogenerator is proposed. The current generated by the nanogenerator is 18 nA under mechanical stress of 600 nN. The obtained piezoelectric nanogenerator parameters are used to estimate the parameters of the hybrid-carbon-nanostructures-based piezoelectric energy converter. Obtained results are promising for the development of efficient energy converters for alternative energy devices based on lead-free ferroelectric films.

“…The conversion of mechanical energy (from waste vibrations) into electrical energy can be done by electromagnetic [36][37][38][39], piezoelectric [33,40], or electrostatic [41][42][43] mechanisms of transduction. The piezoelectric transduction mechanism is the most efficient mechanism for microelectronics [44], wireless sensors [45], and nanoelectronics [46] because they are easy to fabricate [47,48] and are able to harvest energy at variable frequencies [49][50][51]. This phenomenon was discovered by Pierre and Jacques Curie in 1880 [52] as having a direct effect (i.e., conversion of mechanical energy to electrical energy [53]), as expressed in Equation (1) [54] and a converse effect (i.e., the conversion of electrical energy to mechanical energy [55]), as expressed in Equation (2) [56].…”

A Review on Mechanisms for Piezoelectric-Based Energy Harvesters

From last few decades, piezoelectric materials have played a vital role as a mechanism of energy harvesting, as they have the tendency to absorb energy from the environment and transform it to electrical energy that can be used to drive electronic devices directly or indirectly. The power of electronic circuits has been cut down to nano or micro watts, which leads towards the development of self-designed piezoelectric transducers that can overcome power generation problems and can be self-powered. Moreover, piezoelectric energy harvesters (PEHs) can reduce the need for batteries, resulting in optimization of the weight of structures. These mechanisms are of great interest for many researchers, as piezoelectric transducers are capable of generating electric voltage in response to thermal, electrical, mechanical and electromagnetic input. In this review paper, Fluid Structure Interaction-based, human-based, and vibration-based energy harvesting mechanisms were studied. Moreover, qualitative and quantitative analysis of existing PEH mechanisms has been carried out.
