MXene-based multi-component conductive hydrogel with synergistic crosslinking networks for high-performance wearable sensors

as a dynamic coordination crosslinker further enhances mechanical toughness. This collaborative design makes it possible to construct a new type of conductive hydrogel system with high mechanical strength, excellent stability, and tunable sensing performance. When attached to human skin, the conductive hydrogel can quickly respond (response time up to 0.089 s) and accurately detect subtle electrical signals associated with joint motion and muscle contraction. Furthermore, real-time signal acquisition and wireless transmission are achieved through an integrated electrochemical workstation and Bluetooth module, enabling efficient motion monitoring. This study provides a promising strategy for designing multifunctional conductive hydrogels for next-generation wearable bioelectronic devices.
