Sweat sensor monitors metabolites to detect gout, metabolic and other disorders

Caltech’s Wei Gao has developed a wearable sensor that monitors metabolites and nutrients in blood by analyzing sweat. Previously developed, less sensitive, sweat sensors mostly target electrolytes, glucose, and lactate. Gao develops devices based on microfluidics, which minimize the influence of sweat evaporation and skin contamination on sensing accuracy.  Previous microfluidic-based wearable sensors were mostly fabricated with a […]

Silk patch measures 6 biomarkers in sweat

Wenya He, Yingying Zhang, and Tsinghua and Northwest School colleagues ¬†have developed a silk-based wearable patch which measures glucose, ascorbic acid, lactate, potassium, sodium ions and uric acid concentrations in sweat. Sensors are embedded in a woven graphite-silk fabric. Conductivity is enhanced using graphite doped with nitrogen atoms. The flexible patch is applied to the […]
