摩擦纳米发电机已经广泛用于日常生活中收集各种机械能并转换为电能,作为触摸屏和智能皮肤技术的自供能传感系统。为了提高能量转换效率,设计了一种单电极的摩擦纳米发电机(S-TENG)。将表面含有微米尺度浮雕结构的聚二甲基硅氧烷(PDMS)作为S-TENG的摩擦层,一层厚度为20 nm的铟锡氧化物膜作为电极层,通过外部电路可以输出电能。微米尺度浮雕结构增强了摩擦层的电学性能。在室温下使用示波器通过施加不同的外部压力检测了S-TENG的开路电压和短路电流。测试结果表明,制备的S-TENG的开路电压达到了80 V,短路电流达到了1μA。
Abstract：The triboelectric nanogenerator has been widely used in daily life to collect various mechanical energies and convert them into electrical energy, as a self-powered sensing system for touch screen and smart skin technology. To improve the energy conversion efficiency, a single-electrode triboelectric nanogenerator(S-TENG) was designed. A polydimethylsiloxane(PDMS) film with micro-relief surface structure was used as the friction layer of the S-TENG, and an indium tin oxide film with a thickness of 20 nm was used as the electrode layer, the electrical energy could output through an external circuit. The micro-relief structure enhances the electrical performance of the friction layer. An oscilloscope was used to detect the open-circuit voltage and short-circuit current of the S-TENG by applying different external pressures at room temperature. The test results show that the open-circuit voltage and short-circuit current of the prepared S-TENG reaches 80 V and 1 μA, respectively.
