Abstract Conductive gels hold promise for human‐machine interaction (HMI) devices but face limitations in brittleness, solvent reliance, and fatigue resistance. These challenges are addressed by designing a solvent‐free, stretch‐oriented double‐network eutectogel integrating high‐molecular‐weight polyacrylamide (structural reinforcement) with dynamic poly(acrylic acid)/choline chloride deep eutectic network (ionic conductivity). Synergistic effects between molecular chain entanglements stretch‐induced alignment enhance mechanical robustness energy dissipation, achieving tensile strength of 30.70 MPa, elongation 703%, record‐high toughness 133.86 MJ m −3 (surpassing reported eutectogels). Crucially, the aligned microstructure preserves conductive pathways, enabling multimodal sensing high sensitivity ( GF = 1.4 at 250% strain; TCR 14.7% °C −1 ) stability (>300 cycles, without abrupt signal drift). Solution‐based processing compatibility facilitates scalable fabrication ultrathin coatings printed patterns, demonstrated functional HMI devices: somatosensory glove (joint motion accuracy, latency <17 ms), capacitive touchscreens (latency <34 temperature sensors (high thermal resolution). By resolving strength‐flexibility paradox, this work provides platform wearable systems requiring transparency, ultrahigh strength, intrinsic flexibility, environmental adaptability.

Abstract Supramolecular polymeric materials have exhibited attractive features such as self-healing, reversibility, and stimuli-responsiveness. However, on account of the weak bonding nature most noncovalent interactions, it remains a great challenge to construct supramolecular with high robustness. Moreover, usage units is usually necessary promote formation robust materials, which restrains their applications. Herein, we describe construction highly polymer networks by using only tiny amount metallacycles crosslinkers. A norbornene ring-opening metathesis copolymer 120° dipyridine ligand prepared self-assembled 60° or Pt(II) acceptor fabricate metallacycle-crosslinked networks. With 0.28 mol% less pendant form metallacycle crosslinkers, mechanical properties polymers are significantly enhanced. The tensile strengths, Young’s moduli, toughness reinforced reach up more than 20 MPa, 600 150 MJ/m 3 , respectively. Controllable destruction reconstruction further demonstrated sequential addition tetrabutylammonium bromide silver triflate, indicative good stimuli-responsiveness These remarkable performances attributed thermodynamically stable, but dynamic metallacycle-based coordination complexes that offer strong linkages adaptive characteristics.
