Great story! Graphene is emerging as the universal alternative for the conductor, insulator, semiconductor and now magnetic material. Apart from being lighter, electronic gadgets using graphics are going to be faster (because of high electron mobility), more energy-efficient and smaller.
Graphene could serve as the conductor, insulator, semiconductor and now the magnetic material in future electronics. Silicon keeps on going by innovating, but the fact that carbon can substitute for metals as interconnects gives it a little cited advantage. Namely, that if all the copper conductors in a mobile device were made from graphene, then the device would be less than half the weight it is today. If everything in future handheld electronics was crafted from carbon films, they could become almost as light as styrofoam.
Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion.
