Flexible conductive elastomers play a pivotal role in biosensing, electronic skin, and wearable devices. However, fabricating self-healing with superior mechanical properties remains formidable challenge. Here, we introduce simple strategy for the preparation of flexible elastomer that integrates stretchability, conductivity, capabilities. Initially, lipoic acid (LA) deep eutectic solvents (DES) are thermally initiated ring-opening copolymerized, yielding linear copolymer P(LA-DES). This polymer is then integrated polyurethane by intermolecular hydrogen bonds, followed incorporation Fe3+ ions to form dynamic cross-linked network containing disulfide metal coordination. supramolecular not only exhibits remarkable but also demonstrates stable reliable signal response capabilities when used as strain sensor. The possesses tensile strength 4.63 MPa an elongation at break 893%, electrical conductivity up 2.67 × 10–4 S·m–1. Moreover, it achieves healing efficiency exceeding 90% subjected 80 °C 24 h. Additionally, elastomer-based sensor capable sensitively detecting human joint motion, underscoring its potential applications realm devices health monitoring.
