Fig. 6: Real-time monitoring of electrolytes during prolonged exercise and the influence of different interventions.

a Schematic diagram of the layered assembly structure of the “Lego Bricks” wearable dehydration monitoring sensor. b Two different interference measures are taken to influence the dehydration that occurs in subjects during prolonged exercise. c Real-time change curve of Na+ concentration of subjects during approximately 150 min exercise (top: subjects supplementing with electrolyte water. Bottom: subjects supplementing with electrolytes-free pure water). d Changes in Na+ concentration before and after electrolyte water supplementation and (e) electrolyte-free pure water when subjects are dehydrated (n = 3). The error bars represent the standard deviations of the measured data.
