Knot-Patterned Treble-Weaving Smart Electronic Textiles With Advanced Thermal and Moisture Regulation for Seamless Motion Monitoring

Abstract

Smart e-textiles have shown unique advantages in mediating this interactions with the world. Despite substantial progress, the practical application of e-textiles in wearable technologies remains limited by challenging tasks of integrating both optimal electrical performance and thermal-moisture comfort into a single fabric, particularly at industrial scales. Herein, leveraging a meta-textile structural design, a smart treble-weaving electronic textile (TWET) that combines highly sensitive sensing capabilities with radiative cooling is developed and enhanced sweat management through meta-yarn junction blocks forming hierarchical fabric architectures. Unlike conventional layered fabrics by simply compositing different functional layers, the TWET fabric integrates multimodal sensing, optical and moisture management into an all-in-one construction and leverages its interlacing structures as conduits for heat and moisture transmission, which contributes to outstanding thermal-moisture comfort. Moreover, it is demonstrated that the TWET performs robust monitoring and perception of human motion signals against heat stress. It is also shown that frequency-domain signals resulting from Fourier transformation can interpret and distinguish temporal-spatial features of regulating walking and stepping in place. This meta-textile hierarchical-assembly concept enables integrated thermal and moisture management in next-generation e-textiles, offering great potential for scalable production and multifunctionality through the precise engineering of meta-structures.
