Creation
It was developed by Alex Zettl and a research
team at the University of California in Berkeley.
The nanoradio is normally configured as a
receiver but will soon work as an transmitter.

What does it consist of?

• The nanoradio is a tiny radio consisting of a
  carbon nanotube anchored to an electrode, with a
  second electrode just beyond its free end. At
  the core of the nanoradio is a single molecule
  that can receive radio signals.
• They first anchored a nanotube to a metal
  electrode and wired it to a battery. On the
  opposite end is a second metal electrode to
  conduct electrical energy.

How does it work?

• When voltage is applied between the electrodes,
  electrons flow from the battery through the first
  electrode and the nanotube and then jump from the
  nanotubes tip across the tiny gap to the second
  electrode.

5
How does it work?

• It then translates the electromagnetic
  fluctuations of a radio signal into the
  mechanical vibrations of a nanotube.
• Those vibrations are converted into a stream of
  electrical pulses that reproduce the original
  radio signal.

What is a Nanotube?

• A nanotube is a hollow cylindrical molecule
  usually made of carbon.
• Carbon nanotubes are the strongest and stiffest
  materials on earth
• A sheet of nanotubes can operate as a loudspeaker
  if an alternating current is applied

Design
Simply consists of a single carbon nanotube that
works as an all-in-one antenna, tuner, amplifier,
demodulator that produces sound through the
speaker.

Nanoradio Uses

• Better cellular devices
• Improve medical diagnostic equipment
• Create inexpensive wireless environmental sensors
• Play music, possibly replace the iPod
• A desecrate hearing aid that could be implanted
  into the inner ear

Its Miniature Sized!

• The nanotubes that are used to create the
  nanoradio are about 10 nanometers in diameter
• A nanometer is one billionth of a meter!
• The nanoradio could fit inside a living cell
• 100 billion times smaller than standard radios

Benefits to the Business World

• Nanoradios are inexpensive and energy efficient
  which helps our economy
• Shrinking radios would also shrink the device
  that uses them
• Improve nanotechnologies
• Better medical diagnostic equipment
• Creating a new wave of technology
