Researchers from Cardiff University’s School of Engineering created the device, which is about half the size of a standard smartphone. As the BBC reports, a diabetic sticks the device to a patch of skin via the adhesive on the back and then the device uses microwaves to read the blood glucose levels in the user’s body. Since the microwaves emitted from the device can read blood glucose without the need to break the skin, diabetics could save themselves the pain of up to six pinpricks a day that are needed to traditional blood glucose monitors.
“It uses microwaves, but the levels are very, very low. Nowhere near the levels used in domestic cooking,” Professor Adrian Porch, one of its creators, told the BBC. “Think about a mobile phone, we’re about a thousand times less than that level.”MG
