Wow! Printing 90nm and below using a modified standard inkjet printer. That should get them the Nobel Prize. Surely there must be an error of several orders of magnitude in this? Even 90um width is still impressive.
Combine this with home 3D printers and one day some percentage of the manufacturing infrastructure could be replaced. Throw in Arduino and other open-source designs and things really get interesting.
I agree that the technology has a way to go, but that said, it has been a long time since I such a potential game changing technology as Graphene. Only time will tell if it fulfills its promises.
Cool stuff thought.
@PeterClark: timely article... the Printed Electronics conference starts at Santa Clara tomorrow. I was privy to a news brief by Dr. Cathleen Thiele of IDTechEx who says Vorbeck Materials Inc. will have their patented Graphene-based electronic ink will appear in major retail stores sometime in late 2011 (we are there almost!). I will keep you posted most likely with an article on EE Times (if you are going to attend, please let me know, we can meet F2F!).
