The world's tiniest radio is a step closer to reality.
US scientists have
unveiled a detector thousands of times smaller than the diameter of a human hair
that can translate radio waves into sound.
According to a University of
California team, the study marks the first time that a nano-sized detector has
been demonstrated in a working radio system.
Made of carbon nanotubes a
few atoms across, it is almost 1,000 times smaller than current radio
technology.
Peter Burke and Chris Rutherglen incorporated the microscopic
detector into a complete radio system.
