The triboelectric nanogenerator (TENG) is a unique revolutionary technology for harvesting energy from the environment and transforming that energy into electricity. The present paper proposes a double rocker triboelectric nanogenerator (DR-TENG), which is used to harvest energy from intermittent reciprocating motions and ultimately obtain electric energy in a controllable manner. The DR-TENG comprises a mechanical transmission structure, generation unit, and shell. The mechanical energy harvested by the pendulum rod is stored in a spiral spring via the mechanical transmission structure, and the energy is then transformed into controllable electric energy through a switching structure and generation unit. The experimental results show that the open-circuit voltage of the DR-TENG is 450 V, the short-circuit current is 36 $\mu$A, and the peak power is 11 mW. In a water-wave simulation experiment, the DR-TENG powered 400 LEDs in series and a commercial thermometer with a bridge rectifier. This paper provides an effective method for the harvesting of irregular full-stroke energy in an ultra-low-frequency environment.

摩擦电纳米发电机（TENG）是一项独特的革命性技术，用于从环境中收集能量并将该能量转化为电能。本文提出了一种双摇杆式摩擦电纳米发电机（DR-TENG），该发电机用于从间歇性往复运动中收集能量，并最终以可控的方式获得电能。DR-TENG包括机械传动结构，发电单元和壳体。由摆杆收集的机械能通过机械传动结构存储在螺旋弹簧中，然后通过开关结构和发电单元将其转换为可控制的电能。实验结果表明，DR-TENG的开路电压为450 V，短路电流为36$\mu$A，峰值功率为11 mW。在水波模拟实验中，DR-TENG为串联的400个LED和带有桥式整流器的商用温度计供电。本文提供了一种在超低频环境下收集不规则全冲程能量的有效方法。
