Check out the World’s Tiniest Radio

The world’s smallest radio is here! According to a new study, the carbon nanotube- a hollow tube-shaped molecule 10,000 times smaller than human hair- can perform all the basic functions of a radio when it's wired up to a few other simple parts, a new study shows.

When a radio wave of a specific frequency impinges on the nanotube, it begins to vibrate vigorously. An electric field applied to the nanotube forces electrons to be emitted from its tip.

This nanotube radio is over 10,000,000,000,000,000,000 times smaller than the Philco vacuum tube radio from the 1930s.

The single nanotube serves, at once, as all major components of a radio: antenna, tuner, amplifier, and demodulator. (Berkeley physics research)
