Check it, nerds. A team over at the Universidade Nova de Lisboa has reportedly figured out a way to use paper (yes, paper) as an interstrate component of a Field Effect Transistor (FET). In testing, the group "fabricated the devices on both sides of the paper sheet," thus causing the paper to act as the "electric insulator and as the substrate" simultaneously. Remarkably, results showed that performance actually rivaled that of best-in-class oxide thin film transistors, giving revived hope for the realm of disposable devices like paper displays, labels, intelligent packaging, tracking tags, etc. The findings are scheduled to be published this September, after which we're sure any firms interested in taking this stuff commercial will be putting their best foot forward.

We've been following this trend of making stuff invisible for some time now, and the short of it is that invisibility doesn't really quite work as much as we'd like it to for now. But a new result from Northwestern University may be the closest to true "invisible" electronics that we've seen thus far -- honestly, they're really just transparent. A group of scientists, led by Tobin J. Marks, a professor of chemistry, materials science and engineering at Northwestern, have just published a paper in Nature Materials that says that it's possible to produce "transparent, high-performance transistors" on glass and plastics. Dr. Marks said that it was conceivable to be able to construct "displays of text or images that would seem to be floating in space," -- such as a heads-up display of a map built into your windshield, or a visual aid built into a set of goggles for soldiers -- and that new displays based on this technology could be commercially available via his new startup Polyera within 18 months. Heck, if we could use an upgraded version of our bedroom window as a ginormous display to watch TV or movies on, we'd toss our 30-inch LCDs and/or plasma screens in a second.

Our visions of cheap electronic paper may finally come to fruition, if scientists at Stanford University and the University of California, Los Angeles have their way. A joint team from the two universities just published a paper in the journal Nature, which outlines a new technique for mass producing single-crystal organic transistors (previously, the transistors had to be made by hand). According to the researchers, they can print transistors on silicon wafers and flexible plastic, meaning that soon it may be possible to print external inexpensive sensors for commercial products like future generations of LCDs. Exciting times, people, exciting times.

Although you may have never given a thought to what transistors do to repair themselves when certain sectors fail, there are a few organizations who make it their life's work. Researchers from the National Science Foundation, the Semiconductor Research Corporation, and the University of Michigan have a mission to complete before their grant money runs dry: to create semiconductors that can heal themselves without the burdensome redundancy currently used. The goal here, which could seem a tad superfluous until you consider these chips operate in things like airplanes and medical devices -- you know, fairly critical applications -- is to design a semiconductor that runs more efficiently and can be counted on to function no matter how crucial the situation. By designing a chip that can auto-detect a problem, then shift the resources to a functioning area while the chip diagnoses and repairs the issue with help from "online collaboration software," you'll get a slimmer semiconductor that suffers no noticeable loss in performance while self-repairing. If this circuitry talk has your wires all crossed up, here's the skinny: more dependable chips will make everyone's life a bit easier, and if the team's plan is free of defects, we can expect to see prototypes within the next three years.
