Energy Harvesting from Fluid Flow Using Piezoelectric Materials: A Review

Abstract

Energy harvesting from piezoelectric materials is quite common and has been studied for the past few decades, but, recently, there have been a lot of new advancements in harnessing electrical energy via piezoelectric materials. In this regard, several studies were carried out in electrochemistry and fluid flow. Furthermore, consideration of productive and valuable resources is important to meet the needs of power generation. For this purpose, energy harvesting from fluids such as wind and water is significant and must be implemented on a large scale. So, developing self-powering devices can resolve the problem like that, and piezoelectric materials are gaining interest day by day because these materials help in energy generation. This review paper discusses different techniques for harnessing energy from fluid flows using piezoelectric materials. In addition, various vibration-based energy-harvesting mechanisms for improving the efficiency of piezoelectric energy harvesters have also been investigated and their opportunities and challenges identified.

Small wind turbines and their potential for internet of things applications

“…PEGs have been developed for SWTs, necessitating additional exciters due to their non-rotating topology that is not conducive to direct rotor coupling. 230 , 231 Cantilever beam structures are ideal for excitation due to their large deformation and wide frequency response. Mechanical or magnetic excitation are the two common forms available for cantilever beam exciters.…”

Application of Nanofluids for Machining Processes: A Comprehensive Review

“…Until recent research, scientists have carried out nearly all possible methods regarding the application of a single nanofluid as the cutting fluid, whereas they can actually extend their research to hybrid nanofluids [ 127 , 128 , 129 , 130 , 131 , 132 , 133 ], which are more efficient in this application when compared to the single type of nanofluid. This is because hybrid nanofluids [ 134 , 135 , 136 , 137 , 138 , 139 ] show the maximum efficiency in the particular machining process among the different nanofluids. In addition, comparison studies in the branch of lubricating agents are mostly carried out based on the difference in the applications of nanofluids and ordinary fluids.…”

Realizing stretchable energy harvesting film through stretch-buckling conversion of wavy base

“…Piezoelectric devices have been extensively studied over several decades, leading to the development of numerous applications, including ultrasonic imaging [1][2][3][4], high-frequency surgery [5,6], sonar systems [7][8][9], musical instruments [10][11][12][13], and pressure-acceleration sensors [14][15][16][17][18]. Because piezoelectric materials can convert mechanical energy into electrical energy, they hold promise as energy-harvesting devices [19][20][21][22][23][24][25]. In recent years, substantial research has been * Author to whom any correspondence should be addressed.…”
