Progress has been developed in harvesting low-frequency and irregular blue energy using a triboelectric-electromagnetic hybrid generator in recent years. However, the design of the high-efficiency, mechanically durable hybrid structure is still challenging. In this study, we report a fully packaged triboelectric-electromagnetic hybrid generator (TEHG), in which magnets were utilized as the trigger to drive contact-separation-mode triboelectric nanogenerators (CS-TENGs) and coupled with copper coils to operate rotary freestanding-mode electromagnetic generators (RF-EMGs). The magnet pairs that produce attraction were used to transfer the external mechanical energy to the CS-TENGs, and packaging of the CS-TENG part was achieved to protect it from the ambient environment. Under a rotatory speed of 100 rpm, the CS-TENGs enabled the TEHG to deliver an output voltage, current, and average power of 315.8 V, 44.6 μA, and ~ 90.7 μW, and the output of the RF-EMGs was 0.59 V, 1.78 mA, and 79.6 μW, respectively. The cylinder-like structure made the TEHG more easily driven by water flow and demonstrated to work as a practical power source to charge commercial capacitors. It can charge a 33 μF capacitor from 0 to 2.1 V in 84 s, and the stored energy in the capacitor can drive an electronic thermometer and form a self-powered water-temperature sensing system.
近年来，利用摩擦电-电磁混合发电机收集低频和不规则蓝色能量方面取得了进展。然而，设计高效、机械耐用的混合结构仍然具有挑战性。在本研究中，我们报道了一种全封装的摩擦电-电磁混合发电机（TEHG），其中磁体被用作触发装置来驱动接触分离模式摩擦纳米发电机（CS-TENGs），并与铜线圈耦合以运行旋转独立模式电磁发电机（RF-EMGs）。产生吸引力的磁体对被用于将外部机械能传递给CS-TENGs，并实现了CS-TENG部分的封装以保护其免受周围环境的影响。在100转/分钟的转速下，CS-TENGs使TEHG能够输出315.8 V的电压、44.6 μA的电流和~90.7 μW的平均功率，而RF-EMGs的输出分别为0.59 V、1.78 mA和79.6 μW。这种圆柱状结构使TEHG更容易被水流驱动，并证明可作为一种实用的电源为商业电容器充电。它能在84秒内将一个33 μF的电容器从0充电到2.1 V，电容器中存储的能量可以驱动一个电子温度计并形成一个自供电水温传感系统。
