A Robust Core‐Shell Nanofabric with Personal Protection, Health Monitoring and Physical Comfort for Smart Sportswear

Abstract

Smart textiles with a high level of personal protection, health monitoring, physical comfort, and wearing durability are highly demanded in clothing for harsh application scenarios, such as modern sportswear. However, seamlessly integrating such a smart clothing system has been a long‐sought but challenging goal. Herein, based on coaxial electrospinning techniques, a smart non‐woven textile (Smart‐NT) integrated with high impact resistance is developed, multisensory functions, and radiative cooling effects. This Smart‐NT is comprised of core‐shell nanofibers with an ionic conductive polymer sheath and an impact‐stiffening polymer core. The soft smart textile, with a thickness of only 800 µm, can attenuate over 60% of impact force, sense pressure stimulus with sensitivity up to 201.5 kPa−1, achieve temperature sensing resolution of 0.1 °C, and reduce skin temperature by ≈17 °C under a solar intensity of 1 kW m−2. In addition, the stretchable Smart‐NT is highly durable and robust, retaining its multifunction features over 10 000 bending and multiple washing cycles. Finally, application scenarios are demonstrated for real‐time health monitoring, body protection, and physical comfort of smart sportswear based on Smart‐NT for outdoor sports. The strategy opens a new avenue for seamless integration of smart clothing systems.
