We report a triboelectric nanogenerator (TENG) that plays dual roles as a sustainable power source by harvesting wind energy and as a self-powered wind vector sensor system for wind speed and direction detection. By utilizing the wind-induced resonance vibration of a fluorinated ethylene-propylene film between two aluminum foils, the integrated TENGs with dimensions of 2.5 cm × 2.5 cm × 22 cm deliver an output voltage up to 100 V, an output current of 1.6 μA, and a corresponding output power of 0.16 mW under an external load of 100 MΩ, which can be used to directly light up tens of commercial light-emitting diodes. Furthermore, a self-powered wind vector sensor system has been developed based on the rationally designed TENGs, which is capable of detecting the wind direction and speed with a sensitivity of 0.09 μA/(m/s). This work greatly expands the applicability of TENGs as power sources for self-sustained electronics and also self-powered sensor systems for ambient wind detection.
我们报告了一种摩擦纳米发电机（TENG），它通过利用两片铝箔之间的氟乙烯丙烯薄膜的风致共振振动，既能作为可持续的能源，为风速和风向检测的自供电风矢量传感器系统提供能量，也能作为自供电风矢量传感器系统。该集成的 TENG 尺寸为 2.5 cm × 2.5 cm × 22 cm，在 100 MΩ 的外部负载下，输出电压高达 100 V，输出电流为 1.6 μA，相应的输出功率为 0.16 mW，可直接点亮数十个商用发光二极管。此外，还基于合理设计的 TENG 开发了自供电风矢量传感器系统，能够以 0.09 μA/（m/s）的灵敏度检测风向和风速。这项工作极大地扩展了 TENG 作为自供电电子设备和环境风检测自供电传感器系统的电源的适用性。
