Flexible, Highly Conductive Ink
For the past few years, researchers have been trying to develop marketable uses of graphene, a tiny layer of carbon within graphite that conducts electricity extremely well. Vorbeck Materials recently became one of the first companies to do so with Vor-ink, a graphene ink that can be used to print circuit boards for electronics, such as store security tags and cell-phone keypads. Graphene ink is less expensive and more flexible than existing standards: The ink can be printed on a variety of materials, and the resulting circuit board can be bended or peeled off like a sticker.
