基 金：supported by the National Key R&D Program of China(No.2018YFA0108100) the National Natural Science Foundation of China(No.62104009) Experiments on human sweat were conducted in accordance with the approved protocol from the institutional review board at Peking University Third Hospital,Beijing,China(No.M2021610)
主 题：time sequential sensing uric acid Tesla valves laser engraving technology
摘 要：The concentration of biomarkers in sweat can be used to evaluate human health,making efficient sweat sensing a focus of *** flow channel design is often used to detect sweat velocity,it is rarely incorporated into the sensing of biomarkers,limiting the richness of sensing *** this study,we report a time sequential sensing scheme for uric acid in sweat through a sequential design of Tesla valve *** electrodes for detecting uric acid and directional Tesla valve flow channels were fabricated using laser engraving technology to realize time sequential *** performance of the channels was verified through *** time sequential detection of uric acid concentration in sweat can help researchers improve the establishment of human health management systems through flexible wearable devices.
