Ubiquitous vapor and low-grade heat are widely available in nature and provide abundant, clean sources for developing new types of power generators. Herein, we demonstrate high-performance power, driven by vapor and heat for portable electronics in ambient environments. Based on the ternary aggregate of a polyelectrolyte, conducting polymer and a redox couple, the vapor and heat dual-drive electric generator (VHG) of 1 cm² offers an open circuit voltage of 0.9 V, and a sustainable short-circuit-current density of up to 0.8 mA cm⁻², much higher than that of single-source generators. Resulting from synergistic double-acting ion migration and the thermogalvanic effect, the high-efficiency VHG can work as a flexible personal energy-supply system to support wearable devices, such as hearing aids, by using body sweat and heat. It can even light a 15 W bulb once compatibly installed in a greenhouse. This work paves the way for sustainable energy generation by effectively collecting multiple types of natural energy comprehensively to realize sustainable applications in different seasons and geographical locations.

用于环境环境中便携式电子设备的蒸汽和热量双驱动可持续电源

无处不在的蒸汽和低品位热量在自然界中广泛存在，为开发新型发电机提供了丰富、清洁的资源。在这里，我们展示了由蒸汽和热量驱动的高性能电源，用于环境环境中的便携式电子设备。^{基于聚电解质、导电聚合物和氧化还原对的三元聚合体，1 cm 2}的蒸汽和热量双驱动发电机 (VHG)提供 0.9 V 的开路电压和可持续的短路电流密度高达 0.8 mA cm ^-2，远高于单源发电机。由于协同双作用离子迁移和热电效应，高效 VHG 可以作为灵活的个人能量供应系统，通过使用身体汗液和热量来支持可穿戴设备，如助听器。一旦兼容地安装在温室中，它甚至可以点亮一个 15 W 的灯泡。这项工作通过有效地综合收集多种自然能源，实现在不同季节和地理位置的可持续应用，为可持续能源发电铺平了道路。
