Abstract

Energy harvesting and energy transmission are the key technologies for self-powered systems; thus, the combination of these two is urgently needed. An innovative electric field resonance (EFR)-based wireless triboelectric nanogenerator (TENG) is proposed herein. By integrating the TENG with a capacitive coupler, the output of the TENG can be transmitted wirelessly from the transmitter to the receiver in the form of an oscillating signal with an energy-transfer efficiency of 67.8% for a 5 cm distance. Theoretical models of the EFR-TENG system are established, showing excellent agreement with the experimental results. It is demonstrated that the flexible EFR-TENG worn on the wrist can drive a digital watch wirelessly or light up at least 40 light-emitting diodes in series. The EFR-TENG is further utilized for spontaneous wireless sensing with a transmission distance up to 2.3 m with high system tolerance, showing the great potential of this novel strategy for energy harvesting and real-time wireless sensing applications.

摘要

能量收集和能量传输是自供电系统的关键技术；因此，迫切需要将这两者结合起来。本文提出了一种基于创新型电场共振（EFR）的无线摩擦纳米发电机（TENG）。通过将TENG与电容耦合器集成，TENG的输出可以以振荡信号的形式从发射器无线传输到接收器，在5厘米距离下能量传输效率为67.8%。建立了EFR-TENG系统的理论模型，与实验结果显示出极好的一致性。结果表明，佩戴在手腕上的柔性EFR-TENG可以无线驱动数字手表，或至少串联点亮40个发光二极管。EFR-TENG进一步用于自发无线传感，传输距离可达2.3米，系统耐受性高，显示出这种新颖策略在能量收集和实时无线传感应用中的巨大潜力。
