Some swedish researches have developed a way to print “loudspeakers” “keyboards” and other multimedia tehnology on simple paper. This new gadget that maybe will be awailble for all peoples is called the “talking paper”.
In one day, in the future peoples will be informed and students will learn from interactive papers with sounds using the tehnology called “talking paper”.
But the researchers, who have shown how to use printable ink instead of wires or other embedded devices like chips in greeting cards to communicate signals on paper, concede that without a way to print the interactive paper cheaply, their invention may never leave the lab.
The current prototype uses an electronically conductive ink that responds to pressure, by a finger or hand, for instance. It also uses printed speakers created with the conductive ink spread over a material — in this case aluminium foil — which covers an empty cavity to form a diaphragm. The areas covered by the conductive ink are linked at the edge of the paper to wires, which relay the signals to a chip embedded with audio files.
The system works like this: When you touch, say, a picture of a new CD recording, the pressure of your hand or finger sends a signal, which is captured by the wire at the end of the paper and forwarded to the chip. The chip, in turn, activates an audio file, which is streamed through the printed speaker also connected to the wire and conductive ink system.
The best part of this project is that the talking paper can be recycled or thrown away, and the companyes that will product this kind of paper will not meat the ECO friendly guis.
