Swedes make talking paper breakthrough

Billboards shout 'buy me'

By Nick Farrell: Friday 08 June 2007, 06:46
A BUNCH of Swedish boffins has worked out a way of putting touch sensors and speakers onto paper.

Mikael Gulliksson, a researcher at Mid Sweden University said the technology could be used to make billboards talk.

Paper surfaces of the two meter high billboards respond to peoples' touch by playing clips from music albums, or spoken dialogue.

The whole lot is made out of paper and ink which is connected to a power supply.

Speakers are made by printing electromagnets out of conductive ink and stretching the paper over a cavity like a speaker cone.

The electromagnets vibrate in response to a current, creating a sound

What will they think of next?
