The Geek Squad might not like this development, but we're excited about it. Engineers at the University of Illinois have developed a self-healing system for electronics that they say can restore conductivity to failed circuitry in "mere microseconds."

Today's ever-denser chips face more reliability problems due to the increasingly sophisticated demands on electronic devices. When one circuit within an integrated chip fails, the whole chip, and even the whole device (and your pressing deadline, of course) can go down with it.

"In a multilayer integrated circuit, there's no opening it up," Nancy Sottos, a professor of materials science and engineering at the University of Illinois at Urbana-Champaign, said in a statement. "Normally you just replace the whole chip. It's true for a battery too. You can't pull a battery apart and try to find the source of the failure."

To get around the need for external intervention and diagnostics (which may not be readily available for spacecraft or defense-based aircraft, for example), the researchers adapted a previous technique they'd developed for self-healing polymer materials.

They placed tiny microcapsules (as small as 10 microns in diameter) filled with liquid metal on top of a gold line functioning as a circuit. When the circuit cracks, the microcapsules break open, releasing the liquid gallium-indium alloy into the gap and restoring electrical flow--up to 99 percent in most cases. The liquid does its bidding in less time than it takes to blink. … Read more

A Taiwanese chipmaker is suing Apple over the use of multitouch technology in several products, including the iPhone, iPod Touch, and forthcoming iPad.

Elan Microelectronics filed a complaint with the International Trade Commission Tuesday, accusing Apple of violating an Elan-owned patent that covers "touch-sensitive input devices with the ability to detect the simultaneous presence of two or more fingers."

Elan claims the iPhone, iPod Touch, MacBook, and Magic Mouse are in violation of Elan's patent, No. 5,825,352, and when the iPad goes on sale this Saturday, it will be too. Elan has asked the ITC … Read more

You walk into your local Bev Mo' or Safeway and you see that some chap with a posh name has given the Chateau Vers Les Colines 90 points.

So it must be worth the $59.99.

But why trust the chap- he's probably half cut when he tries half the wines he recommends- when you can put your faith in the electronic tongue?

Apparently, scientists are now developing an electronic sommelicker that will hopefully prove, like all old Popes and new technologies, infallible.

The tongues are built onto something called a multisensor (oh, you're techies, you'll know … Read more

With all the development of alternative energy today, it was bound to come to this: Introducing solar-powered brainwaves.

Well, not exactly. But this "electroencephalogram device" does use sunlight as well as body heat as a power source for a variety of functions, which researchers hope will include everything from playing video games to monitoring hospital patients, according to Dvice. The lightweight headset, developed by Belgian scientists at the Interuniversity Microelectronics Center, tracks electrical impulses generated by thought or action.

There are many other systems in development to monitor brainwaves in a similar fashion, but this one is focused … Read more
