The actual meat of the discovery is that graphene has been successfully chipped off a block of graphite using a chemical solvent. These flakes are then filtered to remove any larger, print head-clogging chunks, and then turned into a polymer ink. Despite its amazing properties, graphene hasn’t yet found a way into our computers is because it’s currently very hard and expensive to produce, isolate, and use in silicon circuits. Cambridge’s discovery probably won’t help IBM bring 100GHz graphene circuits to market, though — but it could enable, quite literally, wearable computers.
We have the technology.
