Sweat Sensor (1 of 2) (IMAGE) University of Cincinnati Caption The University of Cincinnati developed a sensor that stimulates sweat under a tiny patch even when its wearer is cool and resting. The sensor can provide the same information found in blood except noninvasively and for hours, allowing doctors to track things like illness, dehydration or a medicine's absorption over time.
