论文摘要
这项研究描述了一种压电聚聚（乙烯基氟化物 - 三氟乙烯）/聚乙二醇三甲酸酯能量收割机，用于对风力涡轮机的结构健康监测。压电能量收割机是由聚乙烯二氟 - 三氟乙烯（PVDF-TRFE）层制成的。此外，使用宠物床单，双面微米厚的磁带和PVDF板进行设备制造。为了优化所提出的设备的性能，研究了PVDF-TRFE材料的电气和机械特性。设计，制造和比较了两个不同的压电能量收割机。开发了风测试设置，并以输出电压和电流为特征。此外，将104 NF电容耦合到建议的设备，以存放生成的电压并运行商业压力传感器。收割机的产生功率足以在最大电流和291.34 UA和937.01 mV的电压下驱动MEMS压力传感器，在风力下，功率值为272.99 UW。
This research describes a piezoelectric Poly(vinylidene fluoride-co-trifluoroethylene)/ Polyethylene Terephthalate energy harvester for structural health monitoring of wind turbines. The piezoelectric energy harvester was made of a polyvinylidene fluoride-trifluoroethylene (PVDF-TrFE) layer. In addition, PET sheets, double-sided micron-thick tapes, and PVDF sheets were used for device fabrication. In order to optimize the performance of the proposed device, the electrical and mechanical characteristics of PVDF-TrFE material were investigated. Two different piezoelectric energy harvester devices were designed, fabricated, and compared. A wind test setup was developed, and the proposed device was characterized by output voltage and current. Furthermore, a 104 nF capacitance was coupled to the proposed device to store the generated voltage and run a commercial pressure sensor. The generated output power of the harvester was sufficient to drive a MEMS pressure sensor with a maximum current and voltage of 291.34 uA and 937.01 mV, respectively, under wind pressure giving a power value of 272.99 uW.
