a Water absorption process of arid soil. The liquid flows along the tiny channels in the soil from wet region toward the dry region. At the same time, in areas where the liquid cannot flow through, water will be transferred in the form of moisture diffusion. b Schematic diagram of the structure of mc-WEG. c The water transportation track in mc-WEG. Bottom wf-layer utilize the flow of liquid to generate electricity, and the top md-layer is based on the moisture induced ion migration for electricity generation. A porous polyacrylonitrile membrane is placed between wf-layer and md-layer for water diversion.
