We report on a flexible triboelectric nanogenerator (FTENG) designed using polydimethylsiloxane (PDMS) and aluminium (Al) combinations to convert ambient mechanical energy into electrical outputs. An open-circuit output voltage of ~40 V and short-circuit current density of ~63.6 mA m-2 with power density 0.62 W m-2 was easily obtained from the FTENG. The harvested mechanical energy is used for lighting ~100 light emitting diodes and to operate seven segment display enabling prospects for carbon-emission free environment friendly source for powering portable electronic devices. We have shown the capability of using the FTENG as self-powered weight and pressure sensors. Additionally, flexible design of the FTENG extends its application scope for self-powered tactile sensing in electronic skin for robotic application. The FTENG is simply designed, cost-effective, scalable and high-throughput for possible uses in flexible electronics, self-powered systems and body sensor networks.
我们报道了一种使用聚二甲基硅氧烷（PDMS）和铝（Al）组合设计的柔性摩擦纳米发电机（FTENG），用于将环境机械能转换为电输出。通过该FTENG可轻松获得约40 V的开路输出电压和约63.6 mA m-2的短路电流密度，功率密度为0.62 W m-2。收集到的机械能用于点亮约100个发光二极管并驱动七段显示器，为为便携式电子设备供电提供了无碳排放的环保电源前景。我们展示了将FTENG用作自供电重量和压力传感器的能力。此外，FTENG的柔性设计扩展了其在机器人应用的电子皮肤中进行自供电触觉传感的应用范围。FTENG设计简单、成本效益高、可扩展且高通量，可用于柔性电子、自供电系统和人体传感器网络。
