“…Flexural excitation is chosen in the cantilever beam form since multiple publications demonstrate that the matching "mode 31" piezoelectric connection gives the highest energy conversion efficiency [158,159]. In addition, as illustrated in Figure 5, an extra mass can be supplied to the free end of the cantilever beam to enhance deformation and tune its resonance frequency with regard to the available vibration source [160,161].…”

Mechanical vibrational energy, which is provided by continuous or discontinuous motion, is an infinite source of energy that may be found anywhere. This source may be utilized to generate electricity to replenish batteries or directly power electrical equipment thanks to energy harvesters. The new gadgets are based on the utilization of piezoelectric materials, which can transform vibrating mechanical energy into useable electrical energy owing to their intrinsic qualities. The purpose of this article is to highlight developments in three independent but closely connected multidisciplinary domains, starting with the piezoelectric materials and related manufacturing technologies related to the structure and specific application; the paper presents the state of the art of materials that possess the piezoelectric property, from classic inorganics such as PZT to lead-free materials, including biodegradable and biocompatible materials. The second domain is the choice of harvester structure, which allows the piezoelectric material to flex or deform while retaining mechanical dependability. Finally, developments in the design of electrical interface circuits for readout and storage of electrical energy given by piezoelectric to improve charge management efficiency are discussed.

This paper evaluates the output efficiency and the frequency responses of a designed vibration-based impact mode piezoelectric power generator with additional interfaced plate. Indirect impact towards the piezoelectric disc is generated by sandwiching the interfaced plate between the piezoelectric disc and contact structure. The impact force can be varied by altering the bending stress of the beam. The output efficiency of the piezoelectric disc is found to increase about 87% by utilizing 1mm thickness of the vibrating beam compared to 2mm thickness. The output efficiency with the additional interfaced plate can harvest about 3 times higher than that of without the interfaced plate. In order to investigate the influence of the interfaced plate, two variables such as the interfaced plateâ€™s diameter and height are studied. It is confirmed from the experimental results that the output of the piezoelectric disc is to be inversely proportional to the height and also to the diameter of the interfaced plate.
