Trendhunter readers know that tattoos may be able to react to emotions. Now scientists want to find a way to evolve body art from showing only emotional responses, to a display that can be pre-programmed to show a specific display when activated. This concept would be used for nano-medicine, allowing medical professionals to access data from your skin.
"This 'dermal display' (featured on the winter 2006 cover of Cryonics magazine) would consist of about three billion light-emitting nanorobots capable of rearanging themselves to spell out words and numbers and produce animations for the display," says OhMyNews. "To turn on and control the display, you simply tap it with your finger."
