We haven't seen all that many OLED lighting options, but a group of researchers from the University of Michigan and Princeton University say they could be on the verge of changing that situation, with them now boasting of a new breakthrough that could greatly increase the efficiency of OLEDs. The key to that, it seems, is a combination of an organic grid and some tiny dome-shaped micro lenses that guide the trapped light out of the devices. As the researchers point out, with current OLEDs, only 20% of the light generated is actually released, but they say this new method could boost the efficiency by a full 60%, or about 70 lumens per watt of power. Of course, they're also quick to point out that all of this is still quite a ways away from becoming practical for commercial purposes, although they seem to be optimistic that the eventual production cost for these new and improved OLEDs will be competitive with existing ones.

We love a good anime-inspired mechanical exoskeleton just as much as the next person, but most social contexts don't exactly smile upon lazy nerds doing their best impression of an AT-ST walker. That's why we're rather intrigued by this pneumatic and highly wearable soft exoskeleton put together by some folks at the University of Michigan. The suit is a hybrid system with electronics responsible for pumping the leg around, and a roboticist from the Science University of Tokyo is working on a version for the upper extremities.

While we imagine most Wolverines are focusing their efforts on gathering up the requisite tailgating gear for the onset of fall, a team of researchers at the University of Michigan are busy finding ways to decipher encryption codes "within seconds." The crew has apparently discovered that by "using pulses of light to dramatically accelerate quantum computers," these systems could not only crack "highly encrypted codes" in moments versus years, but it could also "lead to tougher protection of [sensitive] information." Additionally, the findings rely on "quantum dots and readily available, relatively inexpensive optical telecommunications technology to drive quantum computers," which could lead to quicker implementation of quantum level applications. Hackers, meet your dream machine.

Finally all this research into artificial limbs and human strength augmentation -- as if we'd want to lift stuff -- has resulted in a robotic exoskeleton that doesn't help your muscles do more, but instead allows them to do less. It was designed by researchers at University of Michigan, and is currently being tested on healthy subjects. The ankle exoskeleton is fitted with electrodes which are attached to the wearer's leg muscles and allow the robotics to anticipate muscle movement and perform the action itself. At first a healthy user's gait is disrupted by this extra boost, but after about 30 minutes the person learns to use their own muscles less and have the exoskeleton do most of the walking. We figure similar tests done on a blogger would result in total adaptation in about 7 seconds. Of course, the plan down the road is to use these pneumatic artificial muscles to sense the weaker electrical signals being sent by certain people with spinal injuries or neurological disorders to allow them to move with full strength or to rehabilitate old muscle movements, but that testing has yet to begin, and for now the achievements of this project are purely for the lazy at heart.

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.
