From: Out-of-clinic measurement of sweat chloride using a wearable sensor during low-intensity exercise
a Measurement of sweat chloride concentration and sweat volume using a wearable sweat chloride sensor and Macroduct device. b Optical images of the sweat sensor and the smartphone app. c Schematic illustration of the wearable potentiometric sensor. d Representative sweat chloride concentration profile for an individual walking at 1.8 m s−1. e Corresponding sweat volume versus time curve. f The time corresponding to the onset of sweating (tonset) (mean ± SD). g The minimum measurement time (tm). h The sweat chloride concentration measured by the sensor. Cs is the average value obtained from ts to the end of the trial. i Sweat volume per unit area collected in a Macroduct over 30 min from the beginning of the trial. **P < 0.01.
