(Inside Science) -- The quest to track health information without drawing blood has inspired wearables like Fitbit and Apple Watch, but it's also pushing engineers to develop thin sensors that adhere to the skin like a bandage. Some of these devices can struggle to stay sticky, especially when faced with profuse sweating, but a group of engineers recently developed a new type of electronic skin, or e-skin, that can track vital signs and other information even during intense exercise.
Today's most popular wearables are great for everyday consumers' casual use. But they are thick and rigid, and, therefore, they cannot conform to the curvature of the skin. This has led to less accurate measurement of the vitals, said Hanwool Yeon, a materials engineer at MIT and one of the lead authors of the paper published in Science Advancesin June. With its thinness and clinginess, e-skin can close that gap and improve the quality of the measurements of heart rate, body temperature and more.
