Researchers from Purdue University developed a new transparent electrode made from silver nanowires and graphene. ITO, which is currently used for transparent electrodes in touch displays is expensive, non-flexible, brittle and rare. Silver Nanowires is a promising material to replace ITO - and it is already being commercialized for LCD and OLED displays.

The researchers say that coating the silver nanowires with graphene sheets changed the resistance of the electrodes - which dropped to only 22 ohms per square (which is five times better than ITO which has a sheet resistance of 100 ohms per square).
