Two carbon based flexible ink-jet printer circuit solutions in a month! "Graphene printed via ink-jet, ups mobility" (Peter Clarke) on 11/28/2011 in EETimes and now this news. Interesting how related parallel solutions to a problem can appear in such close proximity. I can't wait to see all the applications. I wonder when the first ink jet printer cartridges will be available for us to fabricate our own circuits on our home printers.
