Scientists from Universidade Nova de Lisboa in Portugal have developed the world’s first paper based transistor. More accurately, it is a field effect transistor (FET) with a paper “interstrate” layer. This invention rivals that of the oxide based thin film transistors (TFTs) produced on glass or crystalline silicon substrates and provides the same level of performance as TFTs, according to the scientists. This advancement could lead to advanced paper based displays as well as smart labels and green disposable electronics in the not too distant future.

The development process entailed fabricating the device on both sides of the paper sheet. Using this method, the paper acts simultaneously as the electric insulator and as the substrate. From the results, the electric characterization of the devices revealed that the performance from the hybrid FETs outshined the amorphous silicon TFTs.
TFOT recently covered new strong, light, and stretchy materials developed at the Swiss Federal Institute of Technology in Zurich, Switzerland. TFOT also covered nanowires that make bendy solar cells developed at A*STAR Institute of Microelectronics in Singapore. Also, be sure to check our extensive look at the future of electronic paper. Additional information on the new paper transistors can be obtained at the Universidade Nova de Lisboa’s website. |

I feel this is a very good invention. Even an all-electronic paper telephone or an internet device eventually could be made mostly out of this and like materials! |
