Abstract Cellulose consists of a natural, rigid polymer that is widely used to improve the mechanical and water‐holding properties hydrogels. However, its abundant hydroxyl groups make it highly absorbent free water, leading swelling behavior. This increased water content will also decrease adhesive performance. In this study, cellulose successfully hydrophobically modified reduce absorption water. Gelatin then cross‐linked with through Schiff‐base reaction, resulting in bound content. significantly enhances resistance permeability, improves freeze–thaw stability hydrogel. Due internal hydrophobicity, molecules can quickly penetrate into interior, reducing their residence time on hydrogel surface. allows maintain high adhesion natural environments, achieving an strength up 3.0 MPa wood bamboo‐based materials. The retain even after prolonged exposure humid environment. Additionally, Na + ions enhance electrical conductivity sensitivity (gauge factor (GF) = 1.51), demonstrating potential applications flexible sensing.

Abstract Conductive hydrogels hold great promise for flexible electronics. However, the simultaneous achievement of satisfactory mechanical strength, outstanding environmental tolerance, high sensitivity, and multiple sensing applications in a single conductive hydrogel remains significant challenge. Herein, ionic polymer‐based with double network consisting [2‐(methacryloyloxy)ethyl] trimethyl ammonium chloride (DMC), 2‐hydroxyethyl acrylate (HEA) silver nanoparticle decorated cellulose nanocrystal (CNC@Ag) are prepared by facile one‐pot method. The resultant (CDH) exhibits stretchability, self‐adhesion, excellent environment tolerance (from −60 to 60 °C), long‐term stability (60 days), effective UV‐shielding, strong antibacterial properties. Significantly, CDH displays conductivity rapid response due its polymer CNC@Ag. Therefore, CDH‐assembled sensor can accurately detect signals from both strain pressure deformations, exhibiting sensitivity reliability human motion detection, signal transmission, object recognition, tactile sensing. More interestingly, collaborating development board, CDH‐based be developed as an emergency alarm realize prompt alarms dangerous situations. Overall, this work presents strategy fabrication remarkable properties, making it possible multifunctional wearable
