UC Berkeley team creates world smallest radio

The San Jose Mercury News reports UC, Berkeley researchers have created and listened to tunes on a "nanoradio" one ten-thousandth the diameter of a human hair. The scientists heard their first FM broadcast of Derek & The Dominos’ "Layla" and the Beach Boys’ "Good Vibrations" transmitted from across a room.


Team leader Alex Zettl says the nanoradio, a single nanotube, works as an all-in-one antenna, tuner, amplifier and demodulator for both AM and FM. In a regular radio, an antenna captures radio waves from different stations. The nanoradio detects radio signals as it vibrates thousands to millions of times per second in tune with a radio wave.
