In this study, a ratchet‐like wheel‐based and spring‐assisted sustainable triboelectric nanogenerator (RS‐TENG) is fabricated for an efficient harvesting of rotational motion. The multitooth structure of the ratchet‐like wheel and force of the spring are used to convert the rotational motion induced by mechanical energy in the environment (such as wind energy) into a reciprocating linear motion of the movable parts, making two triboelectric layers of each sub‐triboelectrification unit produce contact–separation motion to achieve power output. The power output of one subunit is ≈0.37 mW at a uniform speed of 60 rpm, and the power output can increase to 6.05 mW by parallel connection of six subunits. The RS‐TENG with parallel connection of six subunits exhibits an open‐circuit voltage of 320 V throughout the 8 h of continuous operation (≈345 600 contact–separation events), reflecting its excellent durability and robustness. The thermometer can be stably powered at a wind speed of 15.5 m s⁻¹ by the rectifier circuit and a 330 µF commercial capacitor. The above experiments show that RS‐TENG can not only harvest the mechanical energy around the environment for self‐powered sensing, but also exhibit an improved output performance and outstanding robustness.

坚固的摩擦式纳米发电机，具有棘轮式基于轮的设计，可用于收集环境能量

在这项研究中，制造了一种棘轮状的基于轮的弹簧辅助可持续摩擦电动纳米发电机（RS-TENG），以有效地捕获旋转运动。棘轮状齿轮的多齿结构和弹簧的力用于将环境中的机械能（例如风能）引起的旋转运动转换为可移动部件的往复线性运动，从而使每个摩擦层成两层次摩擦带电单元产生接触分离运动以实现功率输出。在60 rpm的均匀速度下，一个子单元的功率输出为≈0.37 mW，通过六个子单元的并联连接，功率输出可以增加到6.05 mW。带有六个子单元并联的RS-TENG在连续运行的8小时内（约345 600个接触分离事件）表现出320 V的开路电压，反映出其出色的耐用性和耐用性。温度计可以在15.5毫秒的风速下稳定供电^-1由整流电路和330 µF商用电容器组成。以上实验表明，RS‐TENG不仅可以收集周围环境中的机械能以进行自供电传感，而且还可以显示出改善的输出性能和出色的鲁棒性。
