Abstract The construction of biomass-based conductive hydrogel e-skins with high mechanical properties is the research hotspot and difficulty in field biomass materials. Traditional collagen-based hydrogels, constructed by typical “bottom–up” strategy, normally have incompatible problem between property collagen content, extraction often necessary. To solve these problems, inspired content animal skins, this work proposed a “top–down” which was unnecessary skin skeleton (SCS) 3D network structure woven natural fibers goatskin preserved used as basic framework hydrogel. Following four-step route, namely, pretreatment → soaking AgNPs (silver nanoparticles) solution mixed containing HEA (2-hydroxyethyl methacrylate) AlCl 3 polymerization, successfully achieved fabrication new skin-based e-skin (tensile strength 2.97 MPa, toughness 6.23 MJ·m −3 breaking elongation 428%) using raw material. developed (called PH@Ag) possessed unique encapsulated PHEA, exhibited satisfactory adhesion, considerable antibacterial property, cytocompatibility, conductivity (3.06 S·m −1 ) sensing sensitivity (the maximum gauge factor 5.51). PH@Ag could serve strain sensors to accurately monitor recognize all kinds human motions such swallowing, frowning, walking, so on, thus anticipated application prospect many fields including flexible wearable electronic devices, health motion monitoring.

Conductive hydrogels as promising candidates of wearable electronics have attracted considerable interest in health monitoring, multifunctional electronic skins, and human-machine interfaces. However, to simultaneously achieve excellent electrical properties, superior stretchability, a low detection threshold conductive remains an extreme challenge. Herein, ultrastretchable high-conductivity MXene-based organohydrogel (M-OH) is developed for human monitoring machine-learning-assisted object recognition, which fabricated based on Ti3C2Tx MXene/lithium salt (LS)/poly(acrylamide) (PAM)/poly(vinyl alcohol) (PVA) hydrogel through facile immersion strategy glycerol/water binary solvent. The M-OH demonstrates remarkable stretchability (2000%) high conductivity (4.5 S/m) due the strong interaction between MXene dual-network PVA/PAM matrix incorporation LS, respectively. Meanwhile, sensor enables with sensitivity limit (12 Pa). Furthermore, pressure mapping image recognition technology, 8 × pixelated M-OH-based sensing array can accurately identify different objects accuracy 97.54% under assistance deep learning neural network (DNN). This work comprehensive performances high-conductive would further explore extensive potential application prospects personal healthcare, interfaces, artificial intelligence.
