چکیده
Given its versatility in drawing power from many sources the natural world, piezoelectric energy harvesting (PEH) has become increasingly popular. However, capacities could be enhanced further. Here, a mathematical model that accurately simulates dynamic behavior and harvested can facilitate further improvements performance of devices. One goals this study is to create dependable reduced-order multi-purpose gyroscope. This will make it possible compute voltage electrical semi-analytical manner. The often modeled as an average value across whole electrode surface We propose which provides practical insights toward optimizing system by considering spatially varying electric field length. Our framework allows investigation limits applicability modeling assumptions range load resistances. differential quadrature method (DQM) basis for suggested numerical solution. also employed examine under various resistance loads. newly developed evaluated open- closed-circuit conditions proved accurate values have not previously been considered. results show using more versatile when multifunctional harvester. may captured resistances ranging between 103 ? 108 ?. At optimum near 65 KHz, maximum output predicted (SV) 1.3 mV, 1.5 mV open-circuit (OC) model, 2.1 closed circuit (CE) model. high-load resistance, SV OC models all predict 1.9 while CE 3 mV.
