Introduction

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.
