According to New Scientist Magazine, researchers have developed a light-emitting ink.
A team at Dai Nippon Printing in Tokyo, Japan, has used a conventional screen-printing technique to deposit a thin layer of the ink, a luminescent gel, onto a surface. The gel consists of a ruthenium compound that emits a bright light when a voltage is applied to it, along with an electrolyte and silica nanoparticles.
Stop, stop– you had me at “ruthenium compound.” But don’t get too excited:
So far, the ink is only able to emit reddish hues when activated, although the researchers are working on other metal compounds that emit green and blue light…The screen-printing technique allows only rough pixels to be generated, and so the images produced currently are fuzzy.
Y’know, I’m so disappointed in 2009. When I was a kid, I thought by now my T-Shirts would display full video with sound! This theory was based entirely on the imaginary 2015 technology in Back to the Future Part II.
That photo strongly resembles a flux capacitor, so maybe there’s still a chance.
