A self-charging hybrid power unit has been developed by integrating a water-evaporation-induced nanogenerator with a flexible nano-patterned supercapacitor. The nanogenerator can harvest environmental thermal energy and mechanical energy through the water evaporation process, and the supercapacitor can be charged simultaneously. The former offers stable electrical power as output, whereas the Ppy-based supercapacitor shows a capacitance of 12.497 mF/cm with 96.42% retention after 4,000 cycles. After filling the power unit with water as the fuel, it can be fully charged in about 20 min. The power unit can be flexibly integrated with electronic devices such as sensor nodes and wireless transmitters employing the Internet of Things. This new approach can offer new possibilities in continuous future operation of randomly distributed electronic devices incorporated in the Internet of Things.
通过将水蒸发诱导纳米发电机与柔性纳米图案超级电容器集成，开发出了一种自充电混合动力装置。该纳米发电机可通过水蒸发过程收集环境热能和机械能，同时超级电容器能够被充电。前者提供稳定的电力输出，而基于聚吡咯的超级电容器在4000次循环后电容为12.497 mF/cm²，保持率为96.42%。在向动力装置中注入水作为燃料后，大约20分钟即可充满电。该动力装置可灵活地与诸如采用物联网的传感器节点和无线发射器等电子设备集成。这种新方法可为物联网中随机分布的电子设备的未来持续运行提供新的可能性。
