World's Smallest Radio Uses Single Nanotube to Pick Up Good Vibrations


October 31, 2007

nanoradio Wielding a single carbon nanotube 10,000 times smaller than a human hair, University of California, Berkeley, and Lawrence Berkeley National Laboratory physicists have constructed the smallest radio yet. The nanotube vibrates at radio frequencies to receive the signal, then acts as both amplifier and demodulator. With only a battery and sensitive earphones, it can pick up AM or FM. With such a small receiver or transmitter, you could put a tracking collar on a bacterium. Full Story
