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.
