The triboelectric nanogenerator (TENG) holds significant potential for applications in energy harvesting and environment monitoring. However, a notable challenge lies in developing a combined system capable of efficiently harvesting energy and providing real‐time self‐powered sensing. Here, a combined wind energy harvesting and speed sensing (EHSS) system is constructed based on a noncontact electricity‐induced constant‐voltage TENG (EICV‐TENG) that achieves constant output by coupling two different phases and incorporates a parasitic sensing module in a single phase. Through the optimization of system integration, the EICV‐TENG achieves a current density of 28.7 mA m−2 and an average power density of 0.26 W m−2 Hz−1. With an optimal power management, the energy output efficiency of the EICV‐TENG reaches up to 96%. And EICV‐TENG can stably power 32 commercial hygrothermographs connected in parallel with the PMC at a wind speed of 7 m s−1. In addition, the EHSS system demonstrates excellent real‐time sensing performance based on the correlation between the peak number of pulse output in a single phase and wind speeds. This work contributes to the advancement of TENG technology for a combined energy harvesting and self‐powered sensing system in the context of the Internet of Things (IoTs).

基于恒压摩擦纳米发电机的风力采集和速度传感组合系统

摩擦纳米发电机（TENG）在能量收集和环境监测方面具有巨大的应用潜力。然而，一个显着的挑战在于开发一种能够有效收集能量并提供实时自供电传感的组合系统。这里，基于非接触式电感应恒压 TENG（EICV-TENG）构建了组合式风能收集和速度传感（EHSS）系统，该系统通过耦合两个不同的相位来实现恒定输出，并将寄生传感模块集成在单个阶段。通过系统集成的优化，EICV-TENG实现了28.7 mA m的电流密度−2平均功率密度为0.26 W·m−2赫兹−1。通过优化的电源管理，EICV-TENG的能量输出效率高达96%。 EICV-TENG可在7毫秒风速下稳定为与PMC并联的32个商用温湿度计供电−1。此外，基于单相脉冲输出峰值数与风速之间的相关性，EHSS系统表现出优异的实时传感性能。这项工作有助于推动物联网 (IoT) 背景下组合能量收集和自供电传感系统的 TENG 技术的进步。
