Graphene is a sheet of carbon, just one atom thick, which is
electrically sensitive to mechanical deformation and contact
with water. Not only this, but it is highly effective at
repelling water too. It’s also far cheaper to obtain than
Indium, which is used in Indium Tin Oxide (ITO) for current
capacitive touch screen technology. Therefore there is a benefit
to the environment too, by reducing the demand for industrial
mining operations. As explained in our other feature about
Nokia’s Nano-Tech, Graphene is a structure made from Carbon
atoms bonded together in a planar hexagonal pattern. By
definition, sheets of Graphene are only one atom thick, but have
amazing properties. At Nokia World 2011, we found a customised
Nokia 700, whose screen had been given the Hydrophobic coating.
We were told that the Graphene layer is 97% transparent. Indeed,
the screen looked just as crisp as an ordinary 700. This is an
improvement over current ITO technology which is 90%
transparent. A Nokia 700 sporting a Hydrophobic coat
