Hydrogel-based moisture-electric generators (HMEGs) have emerged as a promising technology for sustainable energy harvesting by utilizing ambient moisture. This article highlights recent advancements in HMEG development, focusing on innovative hydrogel designs to enhance output and practical applicability. Hydrogels provide highly efficient medium water absorption ion transport, but their limited moisture generation performance necessitates polymer engineering strategies. Protonation doping the incorporation of other cations, such sodium ions, been shown significantly improve electrical output. Furthermore, dual-network hydrogels both mechanical robustness conversion efficiency. Future research should focus improving scalability through large-scale fabrication techniques, enhancing durability under varying environmental conditions, optimizing properties wearable implantable applications. With continued material innovations, HMEGs hold great potential advancing self-powered electronics solutions.
