摘要：Achieving conductive hydrogels that simultaneously combine high strength, high toughness, and reliable sensing performance remains a major challenge, as mechanical reinforcement often disrupts conductive networks. Inspired by the highly ordered lamellar architecture of the Chondracris rosea exoskeleton, an orientation-regulated conductive hydrogel is developed via a sequential blade-coating self-assembly (SBCSA) strategy. This process constructs a biomimetic lamellar structure with highly aligned MXene nanosheets and interlamellar Ag nanowires (AgNWs) embedded within a polymer matrix, thereby enabling efficient stress transfer and robust conductive pathways. As a result, the SBCSA hydrogels exhibit tensile strengths of 16.67–23.12 MPa, fracture strains of 529–683%, and toughness values of 62.91–80.69 MJ m?3, corresponding to a ~106% increase in strength and a ~73% increase in toughness relative to less-oriented counterparts. Meanwhile, electrical conductivities of 1.62–27.15 mS m?1 are achieved by tuning the MXene content while maintaining high mechanical strength and toughness. Owing to the anisotropic lamellar network, the hydrogels further deliver sensitive, rapid, and durable strain-sensing behavior. Multiscale analyses reveal that the synergistic sliding of aligned MXene lamellae, interlamellar AgNW bridges, and polymer chains governs the simultaneous enhancement of strength, toughness, and electromechanical stability. ? 2026 Elsevier B.V.
