High‐Performance Fully Stretchable Moist‐Electric Generator (Adv. Funct. Mater. 11/2024)

Moist-Electric Generator In article 2311128, Liming Wang, Xiaohong Qin, Swee Ching Tan, and co-workers present a fully stretchable moist-electric generator (FSMEG). This innovative device is achieved by thoughtfully combining a hygroscopic ion hydrogel with a carbon black-coated cotton knitted fabric. The simplicity of this method allows for large-scale integration of FSMEG, unlocking its significant potential to power electronic devices, such as cell phones. Moreover, it serves a dual purpose as a self-powered pressure sensor and facilitates weight identification.
