Abstract Conductive hydrogel‐based flexible electronic skin, or “E‐skin,” patches have garnered significant attention in biomedical engineering due to their capability sense and detect real‐time human motion, health metrics, environmental changes. Nonetheless, challenges such as precision fabrication, enhanced flexibility, superior self‐healing, hydrophilicity, insufficient bioadhesive properties impede clinical application limit advancement wearable bioelectronics. In this context, the development of a highly flexible, shape‐reconfigurable, stretchable, printable conductive “E‐skin” patch for humidity, temperature sensing. This utilizes polyvinyl alcohol/gelatin/carbon nanotubes/cellulose nanocrystals (PVA/Gelatin/CNTs/CNCs PVG/NC) based hydrogel inspired by slime molds. Modifying PVG with CNTs CNCs enhances mechanical viscoelastic properties, thereby facilitating high‐resolution direct ink writing (DIW) 3D printing. The resulting slime‐like demonstrates an electrical conductivity ≈5 ± 0.25 S m −1 , exceptional stretchability (≈1000%). nanocomposite also displays outstanding multiple sensing capabilities temperature, humidity under ambient conditions. Furthermore, PVG/NC showcases remarkable near‐infrared (NIR) responsive attributes, which can be leveraged eradicating pathogenic bacteria chronic wounds exhibit excellent cytocompatibility. research holds immense promise future bioelectronics, particularly non‐invasive medical diagnostics.

Abstract Cellulose nanocrystal (CNC) is one of the most important biomass-derived materials for reinforcing hydrogels. Nevertheless, there a lack comparative studies examining impact CNC synthesized viadisparate methodologies on toughening This study two different CNCs through sulfate hydrolysis and deep eutectic solvent (DES) synthesis methods from Gleditsia sinensis peel, forest residue, compared their effects enhancement mechanical properties SA/PAAM The comprehensive characterizations demonstrated that hydrogels derived from DES-CNC are superior to those S-CNC. DES-CNC/SA/PAAM revealed homogeneous structure with excellent strain (2534%), high transparency (90%), self-adhesiveness (15 kPa). flexible sensor assembled using exhibited accurate real-time monitoring capabilities minor larger strains during movement. To investigate mechanism hydrogels, this work evaluated weak interaction forces between components quantum chemical theoretical calculations, combination wave function analysis method Molecular dynamics (MD) simulation. provides tests forestry biomass sources in hydrogel sensing applications suggests new idea high-value utilization feedstocks.
