A wearable patch for continuous analysis of thermoregulatory sweat at rest

Abstract

Low secretion rates and evaporation pose challenges for collecting resting thermoregulatory sweat for non-invasive analysis of body physiology. Here the authors present wearable microfluidics-based patches for continuous sweat monitoring at rest that enable detection of pH, Cl−, and levodopa for dynamic sweat analysis related to routine activities, stress events, hypoglycemia-induced sweating, and Parkinson’s disease.
