Thermal regulation in warm clothing is essential for enhancing human comfort in cold environments. However, traditional warm clothing lacks the ability to adapt to dynamic changes in the human body's microenvironment. Here, we present an adaptive warm cloth, featuring a filling made of a natural bacterial cellulose membrane that responds to human sweating. The cloth's thickness automatically adjusts from 13 millimeters (under low humidity and no sweating conditions) to 2 millimeters (under high humidity and sweating conditions), expanding the thermal regulation capability by 82.8% compared to traditional warm clothing with an unchanged thickness of 13 millimeters. Modeling results further suggest that deploying this adaptive warm clothing across 20 cities in China could extend the duration of the no thermal stress zone by an average of 7.5 hours. Combining exceptional thermal regulation, high stability, and scalability, this clothing represents a notable supplement to existing thermal management technologies.
保暖衣物中的热调节对于提高人体在寒冷环境中的舒适度至关重要。然而，传统的保暖衣物缺乏适应人体微环境动态变化的能力。在此，我们展示一种自适应保暖衣物，其填充物由天然细菌纤维素膜制成，可对人体出汗做出反应。该衣物的厚度会自动从13毫米（在低湿度和无出汗条件下）调整至2毫米（在高湿度和出汗条件下），与厚度不变为13毫米的传统保暖衣物相比，热调节能力提高了82.8%。建模结果进一步表明，在中国20个城市部署这种自适应保暖衣物，可使无热应激区的时长平均延长7.5小时。这种衣物兼具出色的热调节、高稳定性和可扩展性，是现有热管理技术的显著补充。
