Tell-tale Tattoo

Want a tattoo your parents would approve of?

This is Sandra Tsing Loh with the Loh Down on Science.

For diabetics, tracking blood sugar is important – but annoying. Finger-pricking is painful. Patches that monitor blood sugar are expensive and can come unstuck. Is there a better way?

Enter Ali Yetisen from the Technical University of Munich and his international team. They have developed a way to track blood sugar that’s as awesome as it is convenient!

Their edgy new idea? Tattoos!

Their special ink contains sensors that can measure blood sugar. The tat changes color based on blood sugar level. A smartphone can read the color and convert it to an exact number!

Hassle factor – zero. Cool factor – priceless!
