The operation cost of an intelligent high-speed train system is greatly increased by the enormous energy demand of large-scale signal and sensor networks. However, the wind energy generated by high-speed trains is completely neglected. Herein, a wind-energy-harvesting device, which is based on an elastic rotation triboelectric nanogenerator (ER-TENG), is fabricated to harvest the wind energy generated by high-speed moving trains and power the relevant signal and sensing devices. Due to the significant decrease in friction force resulting from reasonable material selection and elastic structure design, the energy-harvesting efficiency of an ER-TENG is doubled and the durability is increased by 4 times compared to the same characteristics of a conventional rotation sliding triboelectric nanogenerator (RS-TENG). Our findings not only provide an in situ energy-harvesting pattern for an intelligent high-speed rail system by recovering the otherwise wasted wind energy generated by high-speed trains but also offer a potential strategy for large-scale wind energy harvesting by TENGs.

用摩擦电纳米发电机收集风能，用于智能高速列车系统

大型信号和传感器网络对能源的巨大需求极大地增加了智能高速火车系统的运营成本。但是，完全忽略了高速列车产生的风能。在此，制造了一种基于弹性旋转摩擦电纳米发电机（ER-TENG）的风能采集装置，以采集高速列车产生的风能并为相关信号和传感装置供电。由于合理的材料选择和弹性结构设计，摩擦力大大降低，与传统的旋转滑动摩擦电纳米发电机相比，ER-TENG的能量收集效率提高了一倍，耐用性提高了4倍（RS-TENG）。我们的发现不仅提供了通过回收高速火车所产生的原本浪费的风能，实现智能高铁系统的原地能量收集模式，但也为TENG大规模收集风能提供了潜在的策略。
