Maybe you still remember the tattoo which helps to monitor a diabetic’s glucose level. A permanent solution. Now Japanese scientists from the University of Tokyo created a new way for diabetics to monitor their levels.
Instead of putting needles in your body, either to measure your levels or to get the special tattoo, you can also get a special 1mm glowstick inserted underneath your skin. This glowstick will glow whenever your glucose levels will increase. This hydrogel fiber is considered more accurate and stable than its predecessors. It even does not require oxygen and will work for 140 days (in mice that is).
Parties with a diabetic will never be the same.
