Fiber-shaped electrical heaters with high flexibility and excellent adaptability make an ideal candidate for the application of wearable electronics but still suffer from low strength poor durability. Herein, all-in-one Joule-heating fiber capable outstanding mechanical properties, good heating efficiency, long-term stability is reported by using polymer-assisted metal deposition to firmly coat Cu nanoparticles on high-performance liquid crystal polymer (LCP) fibers. Taking advantage LCP, resultant fibers exhibit a satisfying temperature threshold (up 200 °C) immense (2.94 GPa). By virtue dense continuous film, these show resistance (5.51 Ω/cm) ultrafast response rate (12.6 °C·s−1) at supplied voltages (0.5–3.5 V). Benefiting levodopa/polyethyleneimine interface design, such maintain nearly constant after repeatable bending, folding, even washing (50 cycles). Based above-mentioned merits, patch function knitted as-made offer therapeutic benefits human body joints. This work demonstrates prospective potential enriching challenging applications fiber-shaped systems.
