Skin-interfaced microfluidic system with personalized sweating rate and sweat chloride analytics for sports science applications.

ABSTRACT: Advanced capabilities in noninvasive, in situ monitoring of sweating rate and sweat electrolyte losses could enable real-time personalized fluid-electrolyte intake recommendations. Established sweat analysis techniques using absorbent patches require post-collection harvesting and benchtop analysis of sweat and are thus impractical for ambulatory use. Here, we introduce a skin-interfaced wearable microfluidic device and smartphone image processing platform that enable analysis of regional sweating rate and sweat chloride concentration ([Cl^-]). Systematic studies (n = 312 athletes) establish significant correlations for regional sweating rate and sweat [Cl^-] in a controlled environment and during competitive sports under varying environmental conditions.
