“…The contact/impact and contactless configurations adopt similar concepts of conventional wind turbines while replacing the electromagnetic generator with piezoelectric energy harvesters. Beside these, there are other configurations of galloping and piezoelectric polymers/films/cantilevers/membrane excited by the direct blowing force or vortex induced by wind. These configurations introduce some novel concepts such as energy harvester trees or grass .…”

Energy harvesting technology may be considered an ultimate solution to replace batteries and provide a long-term power supply for wireless sensor networks. Looking back into its research history, individual energy harvesters for the conversion of single energy sources into electricity are developed first, followed by hybrid counterparts designed for use with multiple energy sources. Very recently, the concept of a truly multisource energy harvester built from only a single piece of material as the energy conversion component is proposed. This review, from the aspect of materials and device configurations, explains in detail a wide scope to give an overview of energy harvesting research. It covers single-source devices including solar, thermal, kinetic and other types of energy harvesters, hybrid energy harvesting configurations for both single and multiple energy sources and single material, and multisource energy harvesters. It also includes the energy conversion principles of photovoltaic, electromagnetic, piezoelectric, triboelectric, electrostatic, electrostrictive, thermoelectric, pyroelectric, magnetostrictive, and dielectric devices. This is one of the most comprehensive reviews conducted to date, focusing on the entire energy harvesting research scene and providing a guide to seeking deeper and more specific research references and resources from every corner of the scientific community.

“…For PE energy harvesting systems, the beam is attached with either an active piezoelectric layer and one passive layer called as unimorph or two piezoelectric active layers on both sides of the passive layer called as bimorph. 78,79 This general mechanism of biomorph is known as triple-layer bimorph. While the inner passive layer is not taken into consideration, it is called as double-layer bimorph.…”

“…123 Also, small-scale piezoelectric transduction is more effective than electromagnetic transduction. So, it can be used in a compact structure like wind turbine 124 and airflow EH, 78 sound wave EH, 125,126 EH based on the impact of raindrop, [127][128][129] etc. It is one of the leading systems given its uncomplicated structure and high power-generation efficiency.…”

This study is based on energy harvesting from vibration and deals with the comparison of different techniques. In the present scenario, energy harvesting has drawn the attention of researchers due to a rapid increase in the use of wireless and small-scale devices. So, there is a huge thirst among scientists to develop permanent portable power sources. In the surroundings, a lot of unutilized energy is wasted which can be collected and used for power generation. Research works have been extensively carried out to develop energy harvesting devices catering to the increasing needs of being efficient and economical. Effective energy harvesting mainly depends on the design of the transducer. Different types of design techniques, material properties, and availability of energy harvesters are reviewed in this paper. The paper aims to explore the advantages and limitations of different energy harvesting principles, advances, and findings of the recent past. This study also discusses some of the key ideas for the enhancement of power output. This paper provides a broad view of the energy harvesting system to the learners, which will facilitate them to design more efficient energy harvesting devices by using different principles.

“…[31][32][33][34][35], collecting FIV energy through PEH has good prospects. Tsujiura et al [36] built a self-excited piezoelectric film twin-chip airflow energy harvester and found that a thinner cantilever reduced the maximum output voltage. Tadokoro et al [37] established an analytical model of a 1-degree-offreedom system with friction and piezoelectric elements, which can be applied to the optimization design of a friction-excited piezoelectric generator oscillator.…”

In this study, piezoelectric elements were added to a reciprocating friction test bench to harvest friction-induced vibration energy. Parameters such as vibration acceleration, noise, and voltage signals of the system were measured and analyzed. The results show that the piezoelectric elements can not only collect vibration energy but also suppress friction-induced vibration noise (FIVN). Additionally, the wear of the friction interface was examined via optical microscopy (OM), scanning electron microscopy (SEM), and white-light interferometry (WLI). The results show that the surface wear state improved because of the reduction of FIVN. In order to analyze the experimental results in detail and explain them reasonably, the experimental phenomena were simulated numerically. Moreover, a simplified two-degree-of-freedom numerical model including the original system and the piezoelectric system was established to qualitatively describe the effects, dynamics, and tribological behaviors of the added piezoelectric elements to the original system.
