Nano Tube Radio
When I saw this on my local television newscast a few nights ago, I was surprised to see how far we have actually come to making a working device so tiny. Perhaps this is just a preview of things yet to come. The future looks very exciting. I can see microscopic sized devices running in fingernail sized wearable technology. I remember reading about carbon nanotubes as a young boy in sci-fi novels. To actually hear news of it in my lifetime is personally exciting to me.
So check this out! Nano Technology just got a whole lot more exciting!
We have constructed a fully functional, fully integrated radio receiver, orders-of-magnitude smaller than any previous radio, from a single carbon nanotube. The single nanotube serves, at once, as all major components of a radio: antenna, tuner, amplifier, and demodulator. Moreover, the antenna and tuner are implemented in a radically different manner than traditional radios, receiving signals via high frequency mechanical vibrations of the nanotube rather than through traditional electrical means. We have already used the nanotube radio to receive and play music from FM radio transmissions such as Layla by Eric Clapton (Derek and the Dominos) and the Beach Boy's Good Vibrations. The nanotube radio's extremely small size could enable radical new applications such as radio controlled devices small enough to exist in the human bloodstream, or simply smaller, cheaper, and more efficient wireless devices such as cellular phones.
