A self-powered device worn as a wristwatch has been developed by researchers and scientists to monitor the wearer’s body chemistry. The device can do numerous calculations, such as monitor dehydration and understand injury recovery. “This technology allows us to test for a wide range of metabolites in almost real-time,” commented Michael Daniele, a co-corresponding author of a paper on the project. Metabolites are used to measure and monitor someone’s metabolism, allowing the device to detect an issue or improve an athlete’s training. Participant’s sweat has already been used to monitor glucose, lactate, pH and body temperature.
