Harvesting energy from human body in multiple ways is pivotal for achieving powering emergency electronics effectively. Herein, we report a hybrid nanogenerator that is based on the coupling of a triboelectric nanogenerator (TENG) and electromagnetic generator (EMG). By utilizing a copper coil in multiroles, the energy grabbing units can operate independently without interfering, revealing a superior performance in scavenging biomechanical energy from human motions. The hybrid device by encapsulation exhibits an excellent environmental stability. When wearing the fabricated device, the TENG and EMG can generate the output voltage about 4 and 1.5 V, respectively, which can be directly stored into a capacitor. By integrating with a battery, the established self‐powered device can actively provide a geographic coordinate in real time in the wild where there is no power supply or network connectivity. Our work paves a way for the further exploration based on hybrid nanogenerators in self‐powered wearable/portable emergency electronics that can be applied in exploration, travel, work, as well as rescue in the wild without power apply and Internet.

构建基于混合纳米发电机的自供电应急电子设备，用于野外生存/救援

从人体收集能量的多种方式对于有效地为应急电子设备供电至关重要。在这里，我们报告了一种混合纳米发电机，它基于摩擦电纳米发电机（TENG）和电磁发电机（EMG）的耦合。通过在多角色中使用铜线圈，能量捕获单元可以独立运行而不会产生干扰，从而在清除人体运动产生的生物力学能量方面显示出卓越的性能。通过封装的混合装置表现出优异的环境稳定性。当佩戴装配好的器件时，TENG和EMG可以分别产生约4 V和1.5 V的输出电压，可以将其直接存储到电容器中。通过集成电池，既有的自供电设备可以在没有电源或网络连接的野外主动主动地实时提供地理坐标。我们的工作为基于混合纳米发电机在自供电可穿戴/便携式应急电子设备中的进一步探索铺平了道路，可将其应用于无需电源和互联网的野外勘探，旅行，工作和救援中。
