Transparent TFT for Temporary Tattoos

USC researchers have demonstrated a low-temperature (and therefore relatively inexpensive, apparently) process for printing transparent TFTs on flexible material able to bend up to 120 degrees which allows for embedding LED to build see-through displays. The prototype disc shown above is 5 inches in diameter and contains around 20,000 nanotube transistors. The researchers suggest the technology could be used for e-paper, smart tags, and artificial skin, as well as an affordable heads-up display that could be put into car windshields. Our suggestion? Couple it with transparent playing cards for the ultimate poker-cheating experience.
