Skin-sniffing wearable keeps tabs on your health | This tiny device could reveal an awful lot about your physiological health, just by measuring the gases you emit through your skin
Did you know you emit a variety of gases through your skin all day long? These vapors, which include carbon dioxide, water vapor, and volatile organic compounds such as ammonia, can reveal vital information about your metabolic status, disease states, and overall health. Now, there's a wearable…
Researchers at Northwestern University in Evanston, Illinois, including the prolific inventor John A. Rogers, have evolved their previous device that analyzed sweat to come up with one that's designed for monitoring Epidermal Molecular Flux (EMF). That last bit is important, because it opens up the device's applications to track infections and wound healing in patients with delicate, sensitive, or damaged skin, including babies, the elderly, and people suffering from diabetes. "The beauty of our device is that we found a completely novel way to assess the status of delicate skin without having to come in contact with wounds, ulcers or abrasions," explained Northwestern’s Guillermo A. Ameer, who co-led the study published in the journal Nature this week.
