The first "completely integrated, extremely bendable circuit" was just demonstrated to the world. The team behind the research is led by John Rogers of the University of Illinois at Urbana-Champaign. The process bonds circuit sheets measuring just 1.5 micrometers (50 times thinner than human hair) to a piece of pre-stretched rubber. That allows the circuits to buckle like an accordion when pulled or twisted without losing their electrical properties. Unfortunately, the materials used thus far are not compatible with human tissue. In other words, no X-ray vision implant for you. X-ray contacts perhaps... quantum-computers now, please Mr. Scientists? Watch a circuit buckle in the video after the break.

Just as Dell calls it quits on the PDA market and flexible displays become more and more common, it makes sense to see a concept device that takes advantage of both opportunities. The Flexi PDA, although still stuck on the drawing board, would present a rubber hinged handheld that could fold open much like a book, giving users a device that's a bit smaller and deeper than current alternatives. Additionally, the casing could easily be ruggedized in order to add water, dust, and shock proofing abilities for those with less delicate work spaces. As expected, this novelty would also pack a QWERTY keyboard, double as a cellphone, and triple as a media player should it ever hit the market, but for now we'll just have to settle with the above picture and a faint hint of hope.

It was just about this time last year that Vivitar snuck out of the woodwork to unveil a few ho hum shooters at PMA 2006, and now the firm is making a literal splash with its 6200W at this year's event. Deemed one of the company's first offerings since the recent acquisition by Syntax-Brillian, the six-megapixel compact touts underwater shooting abilities (up to ten meters), a practically worthless 4x digital zoom, SD card support up to 1GB in capacity, 16MB of built-in storage, PictBridge support, and a two-inch color LTPS display. Wrapped in "rubber armor," this rugged beast should take the abusive conditions of YMCA pools and oceanside fun with ease, but considering there's a complete lack of a flash onboard, we'd suggest snapping your photos whilst barely submerged. While there doesn't look to be a hard release date set just yet, it should reportedly hit shelves for around $233 whenever it lands.

In the run-up to the Iraq war there was a lot of concern that Saddam Hussein might use chemical weapons against our servicemen and women on the battlefield. One of the big problems to keep in mind while combating chemical weapons is that there aren't really any good options for what to wear (a bigger concern than you might think). One option is to don a butyl rubber suit, which keeps nearly everything bad out, but keeps the soldier's sweat in. Unfortunately, trapping heat has some nasty consequences, which can lead to heat stroke or in the worst scenario, death. Scientists at the University of Colorado have just devised a solution to make butyl rubber breathable by combining it with liquid crystals to create 1.2 nanometer-wide pores, which allow sweat to go out, but prevent larger, nastier stuff from getting in. The researchers also add that there may be a way to use this same technology to get that pesky NaCl out of salt water. From the little that we know about textiles science, this sounds like a beefed up version of Gore-Tex -- that reminds us, we'd like our breathable rubber suits in black, please (it'll go with the most of our gadgets that way).
