A NORTH-EAST inventor is to show off to the world the first piano keyboard made out of textiles.

David Lussey, who lives near Richmond, North Yorkshire, invented the keyboard from a revolutionary new type of plastic compound which he created last year.

He will now show off the keyboard to the International Invention Fair in London which starts on Wednesday.

Mr Lussey, who set up Peratech, in Morton Way, Darlington, to exploit the commercial possibilities of the plastic compound, said: "This will be the first demonstration of the unusual things that this plastic can do - which is make textiles touch sensitive.

"The main problem with some musical instruments is the dimensions. With this keyboard you can roll it up and put in your pocket."

The plastic compound is put into a cloth which has the drawing of a keyboard on it.

Presses of the cloth then send signals to an amplifier, which interprets the signals and feeds them into an attached speaker which creates the music.

Mr Lussey's invention will be among hundreds at the Internat-ional Invention Fair, part of the BBC Tomorrow's World Live Event at London's Earls Court from Wednesday to Sunday, July 2.
