The new wonder metal, graphene, is being looked at as a building block for communications and electronic devices on the level of what the transistor was sixty years ago.
Graphene is a one-atom thick, mesh-like (think hexagonal honeycomb or chicken wire), semi metal that will add more battery-life into a smartphone among other breakthrough ideas like bendable displays. It is also ten times stronger than diamonds so its resiliency is perfect for use in a smartphone or any other device that requires super-ruggedness.
