Swedes invent "talking paper"
Using pressure-sensitive ink and printed speakers, new “talking paper” is essentially an interactive billboard. “When you approach the billboard and put your hand on a postcard that shows a picture of a beach, you can hear a very brief description of that beach,” suggests project lead Mikael Gulliksson. The electronics are sandwiched between a heavy-duty cardboard backing and the decorative front layer, so it’s not precisely the flimsy thin stuff we think of as paper, but we could soon see pop star posters which whisper sweet nothings to us in our sleep.
