High Tech Temporary Tattoo

Princeton professor Michael McAlpine has invented a temporary tattoo that can detect things like bacterial infections, allowing for real-time detection and monitoring. Made of graphene, gold wires, and strings of silk, with a miniature antenna, the tattoo would be applied like a temporary novelty tattoo, and send signals to a computer when the substance in question is detected. The tattoo fades quickly, but with the recent grant he received, Prof. McAlpine hopes to increase the staying power of the tattoo and begin testing in hospitals.
