“…In most cases, the structure of an energy scavenger is a cantilever beam with a piezoelectric layer [16,17]. Because of their relatively low resonance frequency and relatively high strain average per specific loading, cantilever beams are considered important [18].…”

Environmental energy harvesting is a major operation in research and industries. Currently, researchers have started analyzing small-scale energy scavengers for the supply of energy in low-power electrical appliances. One area of interest is the use of piezoelectric materials, especially in the presence of mechanical vibrations. This study analyzed a unimorph cantilever beam in different modes by evaluating the effects of various parameters, such as geometry, piezoelectric material, lengths of layers, and the proof mass to the energy harvesting process. The finite element method was employed for analysis. The proposed model was designed and simulated in COMSOL Multiphysics, and the output parameters, i.e., natural frequencies and the output voltage, were then evaluated. The results suggested a considerable effect of geometrical and physical parameters on the energy harvesters and could lead to designing devices with a higher functional efficiency.

“…Vibration energy harvesters (VEHs), which can harvest energy from ambient vibrations and convert it into electrical energy automatically, have become a promising alternative for a range of applications. There are three main approaches to harvesting energy from vibrations, which involve the use of either electrostatic [1][2][3][4][5][6], electromagnetic [7,8] or piezoelectric [9][10][11][12][13][14][15][16][17][18][19] principles. As a general rule, the main challenge in vibrational energy harvesting is that the maximum system performance is achieved when the resonant frequency of the VEH matches the external vibration source.…”
