The First Paper-Based Transistors

Roland Piquepaille found news of research out of Portugal that has resulted in the first paper-based transistors (the original article is less informative than Roland's blog). More precisely, they've made the first field effect transistors (FET) with a paper interstrate layer. According to the research team, such transistors offer the same level of performance as 'state-of-the-art, oxide-based thin film transistors produced on glass or crystalline silicon substrates.' Possible applications include disposable electronics devices, such as paper displays, smart labels, bio-applications or RFID tags. The research will be published in IEEE Electron Device Letters in September.

Paper batteries?

Maybe they could go with paper batteries? Google "paper batteries" for a hundred other links to the same and related stories/technologies.

Not paper transistors dammit

The INTERSTRATE layer is paper now. In a normal FET, the whole thing has a doped silicon substrate functioning as the grid and body, with a (say) metal oxide semiconductor in between as an insulator (interstrate) (MOSFET). They replaced the MOS with paper. It's still a hunk of silicon.

Not the first

The first transistors on paper have been published in 2005:

There is also a paper by the same authors, which I can not find right now.
