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.

Various flexible electrodes have been developed to fulfill the requirements of electrophysiological monitoring. A key feature these is their conformal and seamless contact with tissues or skins. Such usually difficult achieve when detecting signals from hairy skins, e.g., electroencephalogram (EEG) head without shaving hairs noninvasive detection animal signals. Herein, address this problem, a composite paste electrode by mixing polymer matrix conductive nanofillers. The can conformally coat smooth rough surfaces adequate adhesion function collect It records signal-to-noise ratios comparable those commercial patch electrodes. With electrode, direct electrocardiogram (ECG) rabbit skin realized, which conducted invasive needle High-quality EEG also be collected areas dense hair, simplifying detection. This provides convenient comfortable for applications monitoring on surfaces.
