Abstract

Wearable electronics have attracted great attention in recent decades. However, excessive sweat accumulation on skin often has a significant effect on the signal stability, comfort, and safety of electronic skin in practical applications. Herein, a skin-comfortable Janus electronic textile (e-textile) that integrates unidirectional liquid transport and passive radiative cooling properties is developed. This e-textile is fabricated through laser ablation and single-side plasma treatment of carbon nanotubes (CNTs) doped with polydimethylsiloxane (PDMS). The resulting e-textile features a conical pore structure and asymmetric wettability, enabling unidirectional sweat transport from the skin surface to a superhydrophilic silk layer, thereby maintaining a dry and comfortable skin microenvironment. The Janus e-textile achieves a solar reflectivity of 69.2% and a mid-infrared emissivity of 98.3%, reducing the temperature by approximately 5.0 °C compared with a cotton fabric under solar intensity, demonstrating a superior radiative cooling performance. Moreover, the Janus e-textile exhibits stable resistance changes under cyclic stretching and bending, accurately detecting subtle movements across various body parts while reliably acquiring electromyography (EMG) signals. This work positions the Janus e-textile as a pioneering solution for next-generation wearable technologies, integrating thermal and moisture management with advanced resistive strain sensing and EMG capabilities for applications in sports, rehabilitation, and health monitoring.
