From the world of technology comes another mind blowing innovation that simply sweeps you off your feet. The programmable tattoo appears on the skin through nanotubes. The sensory conductors are the size of human hair and displays images on the skin, they are displayed when the power is on and keep appearing even when the power is off. Check out the images to get a rough idea about the mechanism that makes such tattoos work. These programmable tattoos are developed by scientists at Rensselaer Polytechnic Institute. The best that human technology can offer, these programmable tattoos are any man’s dream.
