The new touch-screen film is created and coated onto glass using plasma technology. Researchers from the University of Sydney have discovered a new material that can replace Indium to make touch screens of devices like smartphones as they believe that the world could soon run out of Indium, one of the rarest minerals on Earth. Indium is used in several high-tech devices such as touch screens, smart phones, solar panels and smart windows, in the form of indium tin oxide. This compound is optically transparent and electrically conductive, the two crucial features required for touch screens to work.
