E-Skin Powered by Sweat Can Monitor Health

A researcher has developed an electronic skin that is applied directly on top of real skin. The e-skin, made from soft, flexible rubber, can be embedded with sensors that monitor information like heart rate, body temperature, levels of blood sugar, and metabolic byproducts that are indicators of health, and even the nerve signals that control muscles. It does so without the need for a battery, as it runs solely on bio-fuel cells powered by one of the body’s own waste products.
