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，在使用摩擦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，高效，机械耐用的混合结构的设计仍然具有挑战性。在这项研究中，我们报告了一个完全包装的摩擦电磁混合发电机（TEHG），其中磁体被用作触发接触分离模式的摩擦纳米发电机（CS-TENGs）的触发器，并与铜线圈耦合以运行旋转式独立式模式电磁发电机（RF-EMG）。产生吸引力的磁体对用于将外部机械能传递到CS-TENG，并实现了CS-TENG部件的包装，以保护其免受周围环境的影响。在100 rpm的转速下，CS-TENG使TEHG能够提供315.8 V，44.6μA和〜90.7μW的输出电压，电流和平均功率，而RF-EMG的输出分别为0.59 V，1.78 mA和79.6μW 。圆柱状结构使TEHG更容易被水流驱动，并被证明可以作为向商用电容器充电的实用电源。它可以在84 s内从0至2.1 V为33μF电容器充电，电容器中存储的能量可以驱动电子温度计并形成自供电的水温传感系统。圆柱状结构使TEHG更容易被水流驱动，并被证明可以作为向商用电容器充电的实用电源。它可以在84 s内从0至2.1 V为33μF电容器充电，电容器中存储的能量可以驱动电子温度计并形成自供电的水温传感系统。圆柱状结构使TEHG更容易被水流驱动，并被证明可以作为向商用电容器充电的实用电源。它可以在84 s内从0至2.1 V为33μF电容器充电，电容器中存储的能量可以驱动电子温度计并形成自供电的水温传感系统。
