ABSTRACT In this study, we successfully prepared a composite hydrogel that integrates the superior conductivity of carbon nanotubes (CNTs) with elasticity hydrogels. This was achieved by depositing layer hydroxylated CNTs onto polyacrylamide (PAM) hydrogel. The PAM immersed in CNT dispersion at 50°C and subjected to ultrasonic treatment for 30 min, followed 50% dehydration process achieve densification. enabled adsorption surface, forming robust physical entanglements hydrogen bonds polymer chains. Consequently, significantly strengthened interfacial adhesion between hydrogel, yielding more durable resilient material. Impressively, strength PAM‐CNT surface reached remarkable 61.75 J/m 2 , contributing its good electrical (1.284 ± 0.034 S/m), stability, mechanical properties. Additionally, our study explores application material wearable devices quantifying response pressure, bending, stretching through resistance change measurements. findings indicate research introduces new method preparing conductive hydrogels offers valuable insights their use electronics, biomedicine, various other related domains.

The fabrication of highly antioxidant, elastic, antibacterial, and conductive hydrogels is a significant pursuit in the domain wearable technology. However, achieving these properties simultaneously single hydrogel matrix while maintaining superior sensing capabilities poses substantial challenge. In this study, we developed an advanced with enhanced elasticity, conductivity, antibacterial properties, utilizing natural biodegradable cellulose nanocrystals (CNCs) as reinforcement. This was achieved through synergistic integration glutathione (GSH), selenoglutathione (GSeH), biosynthesized selenium nanoparticles (BioSeNPs), CNC. addition, Saccharomyces boulardii served initial strain, atmospheric room temperature plasma mutagenesis utilized to generate high-yield GSH variant. incorporation GSH, GSeH, BioSeNPs, CNC conferred remarkable antioxidant activity, fatigue resistance, robust properties. study introduces novel methodology for synthesis high-performance hydrogels, paving way their application biomedical engineering sensor
