http://www.removehunger.com/ Techeye team has come up with a new touchscreen display that doesn't require rare and expensive raw materials such as indium.
Indium-tin-oxide (ITO) is normally used for the wafer-thin electrode under the glass surface of a touchscreen display - it's excellent at conducting slight currents and lets the colours of the display show through clearly.
Unfortunately, the stuff is in very short supply, making a readily-available alternative something of a holy grail for the industry. The US Geological Survey reckons that the world supply will be exhausted by 2020 at the latest.
But the Fraunhofer team says it's found an alternative that's just as good - and vastly cheaper. Its main components are carbon nanotubes and low-cost polymers
