The post about the Animated Tattoo yesterday was for April Fools as most people figured out however have a look at this Programmable Tattoo! If you are interested in a bit of a read have a look at the patent.

"For under-the-skin implants, the thinner and more flexible the better. A "nano-skin" polymer film was recently shown by scientists at Rensselaer Polytechnic Institute (RPI). This flexible polymer infused with billions of carbon nanotubes is seen as making possible incredibly thin and flexible displays. Nanotubes are excellent electrical conductors and several research organizations are exploring their use in flexible screen displays.

When suspended between the electrically charged grids the ink spheres can be made to display as either white, black or gray. Digital ink uses very low power and displays an image even when the power is turned off. Each sphere is about the diameter of a human hair and contains positively charged white particles and negatively charged black particles suspended in a clear fluid."

Philips is working on something called SKIN:Tattoo, it looks very interesting!

"Tattoos and physical mutilation are amongst the oldest forms of personal expression and identity. Subcultures have used tattoos as a form of self representation; a visual language communicating personality and status. Philips Design examined the growing trend of extreme body adornment like tattoos, piercing, implants and scarring. 

The Electronics Tattoo film expresses the visual power of sensitive technology applied to the human body. The film subtly leads the viewer through the simultaneous emotional and aesthetic transformations between two lovers."
