The Incredible Shrinking Radio Thu Oct 18, 1:15 PM ET A new wireless radio receiver thousands of time slimmer than a human hair could lead to radios far smaller than those of today. Researchers at the University of California, Irvine, created a carbon nanotube "demodulator" that can translate AM radio waves into sound waves. In a recent demonstration, the researchers used it to transmit classical music wirelessly from an iPod to a speaker several feet away. Carbon nanotubes are man-made microscopic mesh rods composed entirely of carbon atoms. Their incredible strength and other unique properties have led scientists to investigate them for use in everything from nano-electronics and space elevators to scaffolds for growing customized bone. A demodulator converts an AM radio signals into electrical signals that can be fed into a speaker to produce sounds. The new device is about 100 times smaller than similar technology used in commercial wireless radio receivers, said study team member Peter Burke.
