A team of researchers at Cambridge University has used modern miracle material graphene to reinvigorate the old inkjet printer, using graphene ink to print electronic transistors.
And the equipment in the test was surprisingly ordinary. The researchers used a modified Epson Stylus 1500 inkjet printer fitted with a standard Epson S020049 cartridge, filled with ink containing the graphene. The paper used was a bit special -- they printed their Thin Film Transistors on "HMDS coated and O2 plasma treated Si/SiO2". Which doesn't appear to be in stock at Viking Direct.
The end result is a safer form of ink for printing circuits which, thanks to the unique properties of graphene, ought to allow smaller, more efficient circuits to be printed in future. [Arxiv via The Register]
