Checking blood glucose levels used to intend a finger prick and a test-strip, but researchers on the University of Tokyo are offering one other approach: a glowing skin implant . After being injected with the 1 mm wide filament, it monitors your blood sugar by glowing when your level changes. In response to existing glowing glucose sensor technology, this hydrogel fiber is regarded as more accurate and stable than its predecessors, plus it requires no oxygen to operate. To this point, it’s worked in mice for as much as 140 days. Note to future human patients: don’t eat a candy bar before you visit bed unless you desire your arm looking like a nightlight.
