‘Wonder material’ graphene is so tough a sheet as thin as cling film can support an elephant and there’s nothing that can match its conductivity – now scientists have found a way of printing it.
The researchers, from Cambridge University, made flexible electronics from graphene using a humble home printer, bringing devices such as wearable computers a step closer.
The scientists created a graphene-based ink and used a modified Epson printer to produce the thin-film circuits.
Amazing properties: Graphene is the world¿s thinnest, strongest and most conductive material
Printed electronics aren’t a new technology but at the moment they use metal nanoparticle inks, which oxidise after a couple of years and lack the efficiency of silicon-based circuits.
