One of the most enjoyable features found in Apple’s (NASDAQ:AAPL) iPhone and many other smartphones is the capability to interact with these devices by simply touching the screen with your finger. This capability is made possible thanks to a thin coating of a transparent material called indium tin oxide.
However, this vital touchscreen material is in short supply and may even run out sometime in the next decade reports GigaOM. The dwindling indium supplies are reflected in its rising price. The price of indium increased by 25 percent between 2010 and 2011 according to U.S. government data.
This has led device manufacturers like Apple to begin exploring the use of alternative materials that can be used in place of indium. Two potential alternative materials are carbon nanotubes and silver nanowires.
