Wearable sweat skin sensor

This wearable sweat analyzer is more sophisticated than other sweat devices that have come before.  “[University of California at Berkeley] scientists equipped the sensors with spiraling microscopic tubes, otherwise known as microfluidics, which wick sweat from the user’s skin. The sensors track how quickly the sweat travels through the microfluidics, which is a measurement of how much a person is sweating, or their sweat rate. The microfluidics also contain chemical sensors that detect electrolytes like sodium and potassium, as well as metabolites like glucose.”  The developers believe this device could be used to monitor diabetes, dehydration and fatigue, among other things.           MORE
