Talking Paper

Swedish scientists have developed a type of paper that can actually talk to the reader. Using conducive inks which are sensitive to pressure, the paper can be used for advertising and other practical applications, such as reading for the blind. One scientist suggested using the technology on cigarette packs so smokers would hear a warning whenever they go to get a cigarette.

The prototype display features travel locations so that when a viewer pushes on a postcard, a brief description of the locale is given. The technology is expensive and scientists are hoping to not only find cheaper methods of production but also downsize the paper so that it is more useful.

Possibly the coolest thing is that the speakers are also printed. They are placed in one layer, made of the same conducive inks, over a hollow area which creates a diaphragm.
