摘　　要：Self-healable electronics with self-recoverable mechanical properties show a lot of potential in improving the reliability and durability of wearable electronic devices,but it is still challenging.Herein,a self-healing core-sheath thermoelectric(TE)fiber-based temperature sensor was continuously fabricated by coaxial wet-spinning strategy,whose core layer and sheath layer are,respectively,pure Ti_(3)C_(2)T_(x)MXene and self-healing silk sericin(SS)/oxide sodium alginate(OSA)composite.The prepared SS/OSA@MXene core-sheath TE fiber exhibits accurate temperature-sensing at 200-400℃based on a linear relationship between TE voltage and temperature difference.The core-sheath TE fiber that can be integrated into firefighting clothing and timely alert firefighters to evacuate from the fire before the protective clothing becomes damaged.When exposed to flames,SS/OSA@MXene can rapidly trigger a high-temperature warning voltage of 3.36 mV within 1.17 s and exhibit reversible high-temperature alarm performance.In addition,the fractured SS/OSA@MXene can restore up to 89.12%of its original strain limit at room temperature because of the robust yet reversible dynamic covalent bonds between SS and OSA.In this study,an ingenious strategy for developing a durable and wearable TE fiber-based self-powered temperature sensor was proposed.This strategy has promising application prospects in real-time temperature detection of firefighting clothing to ensure the safety of firefighters operating on a fire scene.
