All living creates produce light by default, so do humans. Now researchers from US, China, Korea and Singapore collaborated have collaborated in order to create ultra-thin flexible LED sheets which can be implemented underneath the human skin allowing for medical monitoring and other biomedical applications.
The flexible ultra-thin LED sheets are arrays of 0.5 ?m thick and 100 x 100 ?m square, much smaller then current commercially arrays. It is first printed on a rigid glass substrate and then transferred to an inexpensive biocompatible polymer. Researches successfully tested these small and flexible LED arrays on the fingertip of a glove while immersing it in water, they also implemented it underneath the skin of an animal model.
How long before we see humans walking with commercials on their forehead implemented LED screens?

Thanks DLbingo, Very similar. We urge our contributors to add references as much as possible. Apparently we missed out on this one. What do you think Marco?
I had a 99-word coverage on this: http://www.99fallingapples.com/design-concept/want-a-shining-tattoo-led-under-your-skin/
