Moisture and thermal comfort are critical for long-term wear. In recent years, there has been rapidly growing attention on the importance of the comfortability in wearable electronic textiles (e-textiles), particularly in fields such as health monitoring, sports training, medical diagnosis and treatment, where long-term comfort is crucial. Nonetheless, simultaneously regulating thermal and moisture comfort for the human body without compromising electronic performance remains a significant challenge to date. Herein, a thermal and moisture managing e-textile (TMME-textile) that integrates unidirectional water transport and daytime radiative cooling properties with highly sensitive sensing performance is developed. The TMME-textile is made by patterning sensing electrodes on rationally designed Janus hierarchical gradient honeycombs that offer wetting gradient and optical management. The TMME-textile can unidirectionally pump excessive sweat, providing a dry and comfortable microenvironment for users. Moreover, it possesses high solar reflectivity (98.3%) and mid-infrared emissivity (89.2%), which reduce skin temperature by ≈7.0 °C under a solar intensity of 1 kW m. The TMME-textile-based strain sensor displays high sensitivity (0.1749 kPa) and rapid response rate (170 ms), effectively enabling smooth long-term monitoring, especially during high-intensity outdoor sports where thermal and moisture stresses are prominent challenges to conventional e-textiles.
湿度和热舒适性对于长期穿着至关重要。近年来，可穿戴电子纺织品（电子织物）的舒适性的重要性受到了越来越多的关注，特别是在健康监测、运动训练、医学诊断和治疗等领域，长期舒适性至关重要。尽管如此，在不影响电子性能的情况下同时调节人体的热舒适性和湿度舒适性，迄今为止仍然是一项重大挑战。在此，开发了一种热湿管理电子织物（TMME织物），它将单向水传输和日间辐射冷却特性与高灵敏度传感性能相结合。TMME织物是通过在合理设计的具有润湿性梯度和光学管理功能的双面分层梯度蜂窝结构上图案化传感电极制成的。TMME织物可以单向泵出过多的汗液，为用户提供一个干燥舒适的微环境。此外，它具有高太阳能反射率（98.3%）和中红外发射率（89.2%），在1kW m的太阳强度下可使皮肤温度降低约7.0°C。基于TMME织物的应变传感器显示出高灵敏度（0.1749kPa）和快速响应速率（170ms），有效地实现了平稳的长期监测，特别是在高强度户外运动期间，热应力和湿度应力是传统电子织物面临的突出挑战。
