You all probably know the 'Twitter implant' from the Nano Supermarket. Scientist at the University of Princeton now created the first working prototype.
The implant is actually a sensor which could be tattooed on a tooth. The tattoo could diagnose an infection and transmit that information to a medic. This would be useful for military personnel to determine wether or not a wound becomes infectious.
Although the tattoo does not exactly twitter your coffee intake, it is a big step in monitoring over distance. I wonder which Nano Supermarket product would be next to become reality?
