Abstract
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.
