The world's smallest radio launch

The world's smallest radio is coming soon, after US scientists have introduced a detector that is thousands of times smaller than human hairs, which can turn radio waves into sound.

According to Peter Burke and Chris Rutherglen, two researchers at the University of California, Berkeley, this is the first time that a nanometer scale microscope has been successfully integrated into a complete radio system. .

Made of carbon nanotubes with a width of just a few molecules, the detector is about 1,000 times smaller than the current radio technology. According to the principle, the detector sends radio waves into electrical signals, charging the speakers to produce sound.

The team used it to wirelessly transfer classical music from an iPod to a speaker located a few meters away.

This is compelling evidence that in the future, all of the components that make up the radio can be miniaturized to allow for the creation of true nanowire communication systems.
