Graphene is a crystalline form of graphite (you, know — carbon) that’s one atom thick. It turns out to be a great conductor, and there are efforts to print flexible graphene circuits onto fabric to create wearable electronics.
Britain’s Telegraph newspaper reports on efforts at Cambridge University to print graphene circuits. This first video shows a printed piano keyboard.[youtube https://www.youtube.com/watch?v=Mbx0spQKMFQ]

It’s not all upside with graphene; as we like to say around here, if it was easy, anyone could do it. Here’s a good look at the challenges and benefits of commercial applications of graphene.
