Polyvinyl alcohol (PVA)/polyethylene glycol (PEG) hydrogels, being low-cost and abundant materials, can demonstrate tremendous potential in applications requiring mechanical robustness by harnessing the enhancements afforded a structure inspired articular cartilage (AC). This study presents fabrication of bioinspired PVA/PEG (BPP) hydrogel, characterized their high strength low friction coefficient. By utilizing concrete-like composed PVA particles fibers, BPP hydrogel demonstrates notable properties such as compressive (86%, 29.5 MPa), tensile (265%, 10.5 fatigue resistance, impact cut resistance. Moreover, under submerged conditions, it exhibits coefficient (COF) minimal wear. The packaged sensor sensitivity, linearity, fast response time. Ultimately, we endeavor to apply straightforward yet competent strategy intelligent protective sensing equipment, showcasing extensive prospects for practical applications. Hydrogels have number applications, but many, is required. Here, authors report preparation with cartilage-inspired structure, friction, amongst other properties.

Abstract Given the electrical signal transduction capability and excellent biocompatibility, conductive hydrogels are regarded as ideal candidates for high‐performance strain/pressure sensors applied in personalized medicine. However, there challenges concurrent attainment of flexible hydrogel‐based with remarkable conductivity, sensitivity, reliable stability. Herein, a synergistic strategy based on hole–bridge structure molecular‐crowding effect is proposed to fabricate multifunctional sensor. As‐prepared eutectic hydrogel displays comprehensive performances impressive conductivity (2.81 S m −1 ), boosted mechanical robustness (a tensile strength 2.95 MPa), environmental tolerance (≈79.8% water retention at 50 °C 20 days; frost resistance = −45.3 °C). Notably, hydrogel‐derived stretchable sensor effective antibacterial ability exhibits enhanced sensitivity (gauge factor 4.49) across wide linear range, supporting monitoring joint movement electrocardiographic signals, along on‐demand photothermal treatment. As demonstration, employment efficiently conveying information high‐fidelity handwriting recognition investigated assistance machine learning. This innovative holds high promise future applications wearable‐smart devices integrated wireless transmission modules, exhibiting great potential personal rehabilitation training healthcare monitoring.
