This article proposed a high-performance triboelectric-electromagnetic hybrid wind energy harvester (WEH). By adopting the revolution and rotation movements of tapered rollers, which serve as both the rotor of the electromagnetic generator (EMG) part and freestanding layers of the triboelectric nanogenerator (TENG) part, the WEH can work as a sustainable power source and a self-powered wind speed sensor. When the wind speed is 12 m/s, super-high open-circuit voltage peaks of 47.4 and 683 V can be achieved by the EMG and TENG, respectively, corresponding to the high-power outputs of 62 and 1.8 mW. It was demonstrated that the WEH can easily light up over 600 red light-emitting diodes and even a 5-W globe light. A self-powered wireless temperature and humidity sensing network was also systematically demonstrated. In summary, the proposed WEH exhibits bright future toward IoT applications, such as in border detection, smart buildings, and so on.
本文提出了一种高性能摩擦电-电磁混合式风能采集器（WEH）。通过采用锥形滚子的公转和自转运动，其既作为电磁发电机（EMG）部分的转子，又作为摩擦纳米发电机（TENG）部分的独立层，该风能采集器可以作为可持续电源和自供电风速传感器工作。当风速为12米/秒时，EMG和TENG分别可实现47.4伏和683伏的超高开路电压峰值，对应62毫瓦和1.8毫瓦的高功率输出。结果表明，该风能采集器能够轻松点亮600多个红色发光二极管，甚至一盏5瓦的球形灯。还系统展示了一个自供电无线温度和湿度传感网络。总之，所提出的风能采集器在物联网应用（如边境检测、智能建筑等）方面展现出光明的前景。
