Print your own transistors?

First paper-based transistors | Emerging Technology Trends | ZDNet.com

The research team said that there is currently “an increased interest in the use of biopolymers for low-cost electronic applications. Since cellulose is the Earth’s major biopolymer, some international teams have reported using paper as the physical support (substrate) of electronic devices. But, until now, no one had ever used paper as an interstrate component of a FET.”

Wll, not really. As far as the illustration seems to show, they’re still doing much of the fab the old-fashioned way, and just using the paper for sort-of insulator/separator and for structure. Which is still way cheaper than using silicon, unless you do cost per transistor or something…
