A temperature-adaptive component-dynamic-coordinated strategy for high-performance elastic conductive fibers.

ABSTRACT: Temperature-adaptive elastic conductive fibers (ECFs) are crucial for seamlessly integrating electronic textiles, promoting the development of wearables, soft robotics, and high/low-temperature electronics. Realizing ECFs with balanced elasticity, conductivity, and temperature adaptivity remains challenging due to the difficulty of coupling the mechano-electrical-thermal properties at a microscale fiber. We design a wet-spun ECF consisting of thermoplastic polyurethane (TPU), silver flakes (AgFKs) and liquid metal microspheres (LMMSs) with regularly arranged filler architecture, revealing a cold/thermal stretching activated tricomponent-dynamic-coordination mechanism for autonomously-enhanced electrical conductivity (from ~1070 S cm^-1 at 25 °C to 1160 S cm^-1 at -30 °C
