A sweat-sensing skin patch that connects wirelessly with a smartphone may soon be able to track health during exercise and warn against dehydration. In a new study of 21 healthy volunteers, the soft and stretchable device successfully collected sweat and captured key markers, ranging from sweat rate to glucose and pH.
