Researchers boast of progress with printed electronics

There's certainly no shortage of researchers working on printable electronics these days, but a group from the EU-funded CONTACT project is now boasting of a "major step" towards being able to print electronics on everyday materials. At the moment, they seem to be focused primarily on printing organic TFT displays directly onto glass plates, which apparently required the use of some aggressive solvents that "attack" the organic materials between the TFT and liquid crystal layers. Their current Labratester 1 printer (pictured above) apparently still has some problems precisely lining up each layer, however, but they say that'll be fixed with the addition of some optical cameras in the Labratester 2 machine they're now working on. Eventually, they say the system could be used to easily and cheaply print displays directly on watch faces or glasses, or even print other electronics onto paper or other fabrics.

Researchers develop scalable circuit printing technique

As if there weren't enough "almost theres" in the world of printable circuits, now we've got yet another team developing their own iteration of a printing press for electronics. The group, which includes scientists from DuPont and Organic ID, has reportedly "fabricated a printing plate used to print the source-drain level of an array of thin-film transistors," essentially solving some of the low-resolution constraints seen on prior competition. The goal is to eventually posses the ability to "print large, flexible circuits using machines similar to printing presses," and while it seems to be a ways from commercialization, initial testing and comparisons to more traditionally-created transistors have produced glowing results.
