Abstract The integration of soft, conformable components and rigid microelectronics or devices is a critical frontier in stretchable hybrid device development. However, engineering interconnects capable tolerating high‐stress concentrations preventing debonding failures remain key challenge. Here conductive interconnect derived from the liquid metal conductor with supramolecular confinement reported, reliably connecting soft parts through simple “Heat‐Press‐N‐Go” method. Leveraging dynamic bonding nature polymers, when confined within compartments, not only effectively stabilizes path interconnect, but also offers high adhesion to diverse surfaces, reaching an exceptional electrical stretchability up 2800%. As proof concept, this used assemble wearable including reconfigurable circuits, multifunctional sensors, on‐skin electromyography, exhibiting signal integrity mechanical durability. chip circuit boundless potential enhance adaptability, convenience, versatility electronics across various applications.

Abstract Nanomaterial‐based stretchable electronics composed of conductive nanomaterials in elastomer can seamlessly integrate with human skin to imperceptibly capture electrophysiological signals. Despite the use transfer printing form embedded structures, it remains challenging facilely and stably thin, low‐modulus, adhesive elastomers. Here, a facile‐yet‐simple laser‐induced graphene (LIG)‐assisted patterning method is demonstrated patterned silver nanowires onto an ultra‐low modulus silicone as ultra‐conformal epidermal electrodes. The resulting thin electrodes ≈50 µm exhibit low sheet resistance (0.781 Ω sq −1 ), tissue‐like Young's (0.53 MPa), strong self‐adhesion, excellent breathability. breathable dynamically conformed contact impedance allow for long‐term, high‐fidelity monitoring signals complex environments (even during exercise heavy sweating). Moreover, LIG‐assisted provide robust interface establish stable connection between soft rigid hardware. large‐scale fabrication further provides eight‐channel electromyography system combined deep learning algorithm gesture classification recognition remarkable accuracy (95.4%). results from this study also design guidelines methods next‐generation long‐term dynamic health monitoring, prosthetic control, human‐robot collaborations.
