TRANSISTOR radios were manufactured by american researchers which is smaller than a grain of sand that can outplayed regular radios. scientists from the university of illinois used tiny strands of carbon atoms,known as carbon nanotubes, to make such a small radio.
scientists ensnared technical problems by using quartz wafers to make the device. on being tested , the nano radio easily picked up signals from a near by station.the reception was far better than silicon based radios. The strands used to make the nano radio was made of thousands times smaller than human hair.
The ultimate aim of the research was to develop high performance semiconductors from nanotubes said professor john rogers.
Tiny ants they’d listen to “Layla” and “Good Vibrations” At least, those were the two songs played through a nano-radio made out of a single carbon nanotube fibre — a radio that could fit ‘in the palm of an ant’, according to the US National Science Foundation (surely, that is any one of six palms? Or would it be four palms and two feet?
