In situ analysis of sweat provides a simple, convenient, cost-effective, and noninvasive approach for the early diagnosis of physical illness in humans and is particularly useful in family care. In this study, a flexible and skin-attachable colorimetric sweat sensor for multiplexed analysis is developed using a simple, cost-effective, and convenient method. The obtained sweat sensor can be used to simultaneously detect glucose, lactate, urea, and pH value in sweat, as well as sweat loss and skin temperature. Only 2.5 μL of sweat is enough for the whole test, and the sweat loss and chemical-sensing results can be read out conveniently by naked eyes or a smartphone. In addition, body temperature can also be detected with an additional electrical circuit. Our sweat sensor provides a new, cost-effective, and convenient approach for in vitro diagnosis of multiple components in sweat, and the easy fabrication and cost-effectiveness make our sensor commercializable in the near future.

简单、可贴附在皮肤上的多功能比色汗液传感器

原位汗液分析为人类身体疾病的早期诊断提供了一种简单、方便、经济高效且无创的方法，在家庭护理中特别有用。在这项研究中，使用一种简单、经济高效且方便的方法开发了一种用于多重分析的灵活且可附着在皮肤上的比色汗液传感器。获得的汗液传感器可用于同时检测汗液中的葡萄糖、乳酸、尿素和pH值，以及汗液流失和皮肤温度。整个测试只需2.5 μL的汗液就足够了，汗液流失量和化学感应结果可以通过肉眼或智能手机方便地读出。此外，还可以通过附加电路检测体温。我们的汗液传感器提供了一种新的、具有成本效益的、
