论文摘要
这项研究介绍了聚（乙烯基氟化物共三氟乙烯） /聚乙二醇三甲酸酯（PVDF-TRFE / PET），激光切割，柔性压电能量收割机的仿真，实验和设计考虑。可以从自主传感器系统周围的环境中获取能量，然后将其用于为各种设备供电。本文研究了环境振动的致动手段，这是使用压电能量收割机（PEH）设备的良好候选者。在风测试设备中分析了输出电压特性。有限元建模（FEM）是用于von Mises应力和模态分析的。给出了圆形板的共振频率扫描，质量因子和阻尼比。对于PVDF-TRFE压电层的厚度为18 $ $ m和1.5 mm，半径为1.5 mm，计算了阻尼比为0.117，质量系数为4.284。 $ v_ {max} $计算为与风能设置的984 mV，并将其与FEM输出进行比较。
This study presents the simulation, experimentation, and design considerations of a Poly(vinylidene fluoride co-trifluoroethylene)/ Polyethylene Terephthalate (PVDF-TrFe / PET), laser-cut, flexible piezoelectric energy harvester. It is possible to obtain energy from the environment around autonomous sensor systems, which can then be used to power various equipment. This article investigates the actuation means of ambient vibration, which is a good candidate for using piezoelectric energy harvester (PEH) devices. The output voltage characteristics were analyzed in a wind test apparatus. Finite element modeling (FEM) was done for von Mises stress and modal analysis. Resonance frequency sweeps, quality factors, and damping ratios of the circular plate were given numerically. For a PVDF-TrFe piezoelectric layer thickness of 18 $μ$m and 1.5 mm radius, a damping ratio of 0.117 and a quality factor of 4.284 was calculated. $V_{max}$ was calculated as 984 mV from the wind setup and compared with the FEM outputs.
