Abstract Moisture electric generators (MEGs), which can directly convert chemical energy in moisture into electricity have demonstrated great potential for powering wearable electronics and IoT devices. However, state‐of‐the‐art MEGs suffer from transient power output rely on high relative humidity (RH) as well mild temperature, hampering their practical applications. Herein, a novel high‐performance MEG is reported by designing ionic hydrogel graphene oxide dual‐layered devices, where the water‐enriched enables continuous outputs under various conditions while inherent layering nanochannels effectively regulate ion diffusion stable efficient performance improvement.
