Ipod may have called one of their models nano, but truly nano-sized radios have been tipped as one of the 10 emerging technologies of 2008.
A nano radio consists of a single molecule (a carbon nanotube) which can receive radio signals. The radio works by translating the electromagnetic oscillations of a radio wave into the mechanical vibrations of a nanotube, which are in turn converted into a stream of electrical pulses that reproduce the original radio signal. Of course this means that the first transmission it was successfully tested with was ‘Good Vibrations’ by the Beach Boys.
The nano radio could be incorporated into tiny wireless devices, or even used in medicine to travel around the body, responding to radio signals, perhaps delivering drugs to targeted areas.
