Contact lenses have traditionally been engineered to help the visually impaired see the world around them more clearly--to attain perfect, or close to perfect, vision.

But why not super vision? Why not a lens that could superimpose holographic driving control panels over a pilot's otherwise normal view? Enable Web surfing on the go? Provide a virtual world for gamers that covers their entire field of vision instead of just a plasma screen?

Engineers at the University of Washington have been asking just that as they manufacture first-gen versions of the bionic eye in the form of contact lenses with an imprinted electronic circuit and lights.

"Conventional contact lenses are polymers formed in specific shapes to correct faulty vision," writes Babak A. Parviz, an associate professor at UW who heads a multi-disciplinary group on electronics in contact lenses, in the September 2009 issue of IEEE's Spectrum. "To turn such a lens into a functional system, we integrate control circuits, communication circuits, and miniature antennas into the lens using custom-built optoelectronic components. Those components will eventually include hundreds of LEDs, which will form images in front of the eye, such as words, charts, and photographs."… Read more

Polymer Vision's dream of an all-in-one e-book reader and portable media device has reportedly faded.

The Netherlands-based maker of the Readius folded recently, according to a report in England's Hampshire Chronicle. The company was a spinoff of Philips and had offices in Southampton in the U.K. The local paper says 50 jobs at the Southampton location were lost when the company went bankrupt on July 7.

The Readius was a strange-looking, if ambitious device. Part portable media device, part e-reader, the Readius was innovative in that it used a flexible E-Ink display so it could be folded … Read more

We all get in a big arguments over whether all-in-one devices are more convenient than discrete devices. Cooley thinks discrete devices are un-American. I think the opposite. And Molly has the logical arguments for discrete devices. We also find out a judge has ruled IP addresses can only prove a computer existed and not a person. Good on ya, Judge!

Scientists at the University of Illinois have developed polymers that change color when the material becomes overstressed.

The materials science invention could be used in things like parachute cords, climbing ropes, or added to smart coatings for bridges.

The polymers contain mechanophores--molecules that create a chemical reaction that makes the synthetic material change color when a certain amount of force is exerted upon it.

One of the polymers offered by the scientists as an example of their work is an amber-colored elastomer that turns progressively more orange as it's pulled and then finally red right before it reaches its … Read more

Hyundai's Nuvis concept features some wild ideas--such as an in-cabin Intranet linking the driver and passengers--but more specifically, it is meant to showcase the automaker's lithium polymer battery technology and show its malleability and flexibility of integration.

Scientists at the University of Southern Mississippi developed a polyurethane coating that heals its own scratches when exposed to sunlight. This breakthrough uses chitosan, a substance found in the shells of crabs and shrimp, to make scratches in polymer coating disappear.

"When a scratch damages the chemical structure, the chitosan responds to ultraviolet light by forming chemical chains that begin bonding with other materials in the substance, eventually smoothing the scratch. The process can take less than an hour," according to an article in Yahoo! Tech News.

The self-healing material can be used in the coatings that protect … Read more

I suppose most of the excitement from MacWorld Expo has died down by now, but I'd still like to talk a little about two new Mac laptops introduced at the show-- Apple's own 17" MacBook Pro, and Axiotron's Modbook Pro, a tablet computer made by repackaging the components from Apple's 15" MacBook Pro along with some new parts.

First, the Axiotron product. Externally, the ModBook Pro is radically different from the Apple notebook that provides most of its component parts.

In this publicity photo, the Modbook Pro's beveled edges are apparent. The shape … Read more

The University of Wisconsin-Madison and a Wausau, Wis., company have come up with a 37-inch, bullet and bomb-proof Humvee tire based on a polymeric web so cool looking there's no need for hub caps.

Resilient Technologies and Wisconsin-Madison's Polymer Engineering Center are creating a "non-pneumatic tire" (no air required) that will support the weight of add-on armor, survive an IED attack, and still make a 50 mph getaway. It's basically a round honeycomb wrapped with a thick, black tread.

The military wants an alternative to the current Humvee "run flat" tires, which despite … Read more

SAN DIEGO--Steve Jobs said people "don't read anymore."

Karl McGoldrick hopes the visionary Apple CEO is actually wrong for once.

That's because McGoldrick is the CEO of Netherlands-based Polymer Vision, the only company that right now is working on making e-books in a form that's actually close to traditional books--ones that are mobile, bendable, and, above all, readable.

But the device, called Readius, is not just an e-book reader--it receives e-mail, text messages, and RSS feeds, makes phone calls, and keeps calendar and contact information--in addition to downloading books and newspapers wirelessly.

It caused quite … Read more
