Scientists create world’s smallest nanotube radio

A team of U.S. scientists have created the world’s first nano detector that translates radio signals into sound, according to a BBC report.

“Though we have only demonstrated the critical component of the entire radio system out of a nanotube (the demodulator), it is conceivable in the future that all components could be nanoscale, thus allowing a truly nanoscale wireless communications system,” wrote University of California team members Peter Burke and Chris Rutherglen regarding their incorporated nanotube detector, which wirelessly transmitted a piece of music from a host iPod music player to a nearby speaker.

The team’s breakthrough will appear in November via the American Chemical Society’s Nano Letters, and the notable achievement is also likely to prick the ears of watching companies and consumer industry players interested in evaluating the real-world potential of nanotube technology in everyday electronic devices.

While there are many real-world possibilities to be garnered from microscopic radio technology, related industry challenges regarding the miniaturisation of components such as power supplies, processors and sensors, are presently the main stumbling block to progress.

“Scientists are looking at carbon nanotubes to miniaturise all other technologies as well,” Kris Sangani of the Institution of Engineering and Technology told the BBC. “If you can combine miniaturisation with cost control; that type of technology would be ubiquitous.”
