Measuring Your Sweat, A Health Monitor And Diagnostic Device Is The Future Of Wearable Technology
Scientists are creating a wearable gadget that stimulates and collects sweat via a patch the size of a band-aid, and then analyzes it using your smartphone. Sweat, the cooling system of your body, is made almost completely of water, with tiny amounts of other chemicals, including ammonia, urea, salts, and sugar. Remarkably, these chemicals along with the small molecules and peptides they contain can reveal what is going on inside your body. For this reason, scientists are trying to harness sweat through some form of wearable technology and turn it into a new way to measure and monitor your immediate health. “Sweat contains a trove of medical information and can provide it in almost real time,” wrote Dr. Jason Heikenfeld, associate professor of electronic and computing fsystems, University of Cincinnati, in an article for IEEE Spectrum. Since, well, nearly forever doctors have been extracting fluids from our bodies in order to evaluate some aspect of our health. How many blood tests, ur...
