Wearable sweat sensors have spearheaded the thrust toward personalized health monitoring with continuous, real-time, and molecular-level insight in a noninvasive manner. However, effective sweat sampling still remains a huge challenge. Here, we introduce an intelligent Janus textile band that bridges the gap between self-pumping sweat collection, comfortable epidemic microclimate, and sensitive electrochemical biosensing via an integrated wearable platform. The dominant sweat sampling configuration is a textile with Janus wettability, which is fabricated by electrospinning a hydrophobic polyurethane (PU) nanofiber array onto superhydrophilic gauze. Based on a contact-pumping model, the Janus textile can unidirectionally and thoroughly transport sweat from skin (hydrophobic side) to embedded electrode surface (hydrophilic side) with epidemic comfort. On-body experimentation reveals that the sensitive detection of multiple biomarkers including glucose, lactate, K+, and Na+ is achieved in the pumped sweat. Such smart Janus textile bands can effectively drain epidermal sweat to targeted assay sites via interface modifications, representing a reinforced and controlled biofluids analysis pathway with physiological comfort.

集成式智能Janus纺织品手环，用于自抽汗采样和分析。
可穿戴的汗液传感器以无创方式连续，实时和分子水平的洞察力引领了个性化健康监测的潮流。然而，有效的汗液采样仍然是一个巨大的挑战。在这里，我们引入了智能Janus纺织带，通过集成的可穿戴平台弥合了自吸汗水收集，流行的微气候舒适性和敏感的电化学生物传感之间的差距。汗液采样的主要配置是具有Janus润湿性的纺织品，该纺织品是通过将疏水性聚氨酯（PU）纳米纤维阵列静电纺到超亲水性纱布上制成的。根据联络抽出模型，Janus纺织品可以单向且彻底地将汗液从皮肤（疏水侧）转移到嵌入式电极表面（亲水侧），并具有流行的舒适性。人体实验表明，灵敏检测多种生物标记，包括葡萄糖，乳酸，钾+，而Na +在汗液中达到。这种智能的Janus纺织带可以通过界面修饰有效地将表皮汗水排至目标分析部位，代表具有生理舒适性的增强和受控生物流体分析途径。
