US scientists have successfully developed the “world’s smallest radio”. These are the nano-sized devices that are many thousand times smaller than the diameter of a human hair that can translate radio wave into sounds. The super tiny device is made of carbon nanotubes that is only a few atoms across, which is almost 1,000 times smaller than the current radio technology.
The super tiny radio has been tested for transmitting classical music wirelessly from an iPod to a speaker several metres away from the iPod. Scientists claim those extremely tiny carbon nanotubes would be great to make cluster or network of nanoscaled devices that would be very useful in medicine, commerce and on the battlefield.
