Carbon-based conductor could herald cheap, bendable electronics
Touch screens owe their magic to an electrically conductive film that sits just below the surface. In most devices, this layer is made from a compound known as indium tin oxide (ITO), which is rigid, expensive to manufacture, and requires the rare metal indium. Now, researchers have created a cheap and flexible alternative to ITO that could not only lower costs for touch screens, solar cells, and smart windows, but also enable new classes of bendable, wearable electronics.
