Published: Sept. 15, 2023

Abstract Conductive hydrogels are compelling materials for the development of soft electronics; however, their essential attributes such as high sensitivity, excellent stretchability, and environmental stability have rarely been achieved simultaneously in one hydrogel. Herein, a Kirigami‐inspired strategy is proposed to improve organohydrogel sensitivity without sacrificing mechanical stretchability . The organohydrogels with multiple interpenetrating networks synthesized by introducing sodium alginate nanofibrils conductive MXene nanoflakes into polymer double infiltrated glycerol–water mixtures, featuring remarkable (>5000%), good water retention (>30 days). Kirigami structures further applied enhance strain achieving gauge factor 29.1, which ≈5.5 times that an unstructured organohydrogel. Using sensors, durable glove developed grabbing underwater objects through operating robotic arm, demonstrating subaqueous interactive human–machine interfacing.Meanwhile, integrating wearable sensor machine learning algorithm, Morse code intelligent recognition system demonstrated, enabling real‐time conversion signs speech superior accuracy (>99%) fast response time (≈17 ms). This work offers new route synthesize highly sensitive, stretchable, extremely tolerant organohydrogels, providing promising platform next‐generation electronics.
