Graphene electronics produced on ink-jet printer

Daily Mail : Researchers at the University of Cambridge in the UK have created a graphene-based ink and used a modified Epson printer to produce thin-film circuits, writes Ted Thornhill for the Daily Mail. To create the ink, they dissolved microscopic flakes of graphite in N-methylpyrrolidone. Although printed electronics aren’t new , the Cambridge team replaced the metal nanoparticle inks with graphene, which is lighter, cheaper, more conductive, and more stable. The flexible electronics created from such ink-jet printing could be used in touch screens, photovoltaic devices, and electronic textiles. The group describes the technique in a paper submitted to the arXiv e-print server.
