Swedish Researchers Build Cardboard Piano


Jun 3, 7:19 AM (ET)



STOCKHOLM, Sweden (AP) - It's a mover's dream and sure to capture the fancy of anyone who tickles the ivories: a grand piano made only of cardboard that sounds almost like the real thing.


But don't expect to find one at your local music store just yet. Researchers with Swedish packaging company SCA have only built a few, and those are still being used for tests.


The cardboard piano uses integrated circuits that are pressed onto paper instead of silicon chips or circuit boards. It's based on technology developed to make paper products that change color or include radio-frequency tags for inventory control.


Ulf Carlsson, SCA's head of development and research, said the cardboard piano features all 88 keys. Press one, and the circuit beneath it sends a signal to an external loudspeaker, which plays the appropriate sound.


"It sounds almost like the real thing, but it is much cheaper - and lighter," Carlsson said.


There are no immediate plans to market the piano. Rather, Carlsson said, it's being used to show off the development of next-generation printing techniques.
