Slathering yourself with mud to avoid head-hunting aliens is great and all, but it ain't exactly the paragon of good personal hygiene. Fortunately, researchers have concocted a cleaner and less cakey defense against Predators that's more likely to be mom approved. Fresh on the heels of the microwave invisibility project at the University of Texas at Austin, French researchers have found a way to make a cloak that can hide a subject from thermal imaging devices. The concept uses alternating materials with varying rates of diffusion to move heat around and create a thermally invisible region. Conversely, the technique can be used to concentrate heat in one spot so it gets hot rapidly. Although it doesn't quite have the wow factor of Cornell's invisibility project, the thermal research may prove to be more practical because it also can be used to manage heat and improve cooling in components such as computer chips. Of course, the question now is, can it be used to cloak an entire tank?

However, as part of a marketing plan to call attention to its zero-emissions F-Cell model, the German marque swathed a side of one in LEDs to give it the ultimate in camouflage. You see, in addition to that makeshift display, a Canon 5D Mark II was mounted on the other side of the car so that video of its surroundings could be shown on the LED bodywork -- rendering the car all but invisible to onlookers, as long as they're staring at the left side, of course. Go ahead, head on down to see the magic of digital camo for yourself in the video after the break.

With gobs of fiber optics at their disposal, the researchers have devised a method to distort light in a way that makes events in time undetectable to observers. Initial success in this Pentagon-backed invisibility project has cloaked an event for 40 trillionths of a second, leading Cornell scientists to tout, "You kind of create a hole in time where an event takes place. You just don't know that anything ever happened."

The feat is performed by separating light into more fundamental wavelengths, first by slowing the red and speeding the blue. A resultant gap forms in the beam, which leaves a small window for subterfuge. Then, as the light passes through another set of fibers -- which slow the blue and speed the red -- light reaches the observer as if no disturbance had taken place at all. While the brilliant researchers ultimately imagine art thieves being able to pass undetected through museums with this method, the immediate challenge will be in prolonging the light gap. This could prove frustrating, however, due to the scattering and dispersion effects of light. As Cornell scientists dream of their ultimate heist, visual learners will most certainly want to check the video after the break.

Now, Patrick Baudisch and his team of researchers at the Hasso-Plattner Institute have moved closer to making it a reality, with a new interface that can essentially transfer an iPhone touchscreen to the palm of your hand. The device involves an Xbox-like depth camera, mounted on a tripod, that can register the movements of a person's finger across his or her palm. Special software then determines the actions these gestures would execute on a user's iPhone, before transmitting the commands to a physical phone, via WiFi radio. Unlike MIT's motion-based "sixth sense" interface, Baudisch's imaginary phone doesn't require users to learn a new dictionary of gestures, but relies solely on the muscle memory that so many smartphone users have developed. During their research, Baudisch and his colleagues found that iPhone owners could accurately determine the position of two-thirds of their apps on their palms, without even looking at their device. At the moment, the prototype still involves plenty of bulky equipment, but Baudisch hopes to eventually incorporate a smaller camera that users could wear more comfortably -- allowing them to answer their imaginary phones while doing the dishes and to spend hours chatting with their imaginary friends. Head past the break to see the prototype in action.

Or one that lets you reenact your favorite Metal Gear Solid scenes with Snake's camo turned on? Yup, a Japanese coder by the name of Takayuki Fukatsu has exploited the versatile openFrameworks to give Kinect a mode where it tracks your movement and position, but turns the dull details of your visage into an almost perfectly transparent outline. Of course, you're not actually transparent, it looks to be just the system skinning an image of the background onto the contours of your body in real time, but man, it sure is cool to look at.

In these articles, he'll explore where our industry is and where it's going -- on both micro and macro levels -- with the unique wit and insight only he can provide.

When Apple refreshed the latest version of the iPod nano, the combination of the square form factor, touch display, clip and cool clock app made me think it would make a great watch. I was not alone. I've already seen a number of vendors scrambling to create straps and wrist cases for the nano. While Apple stopped well short of calling it a watch replacement, there's no doubt Cupertino will be looking carefully to see if there's an iWatch in your future.

From Microsoft's Smart Personal Object Technology devices to watches that ran Palm OS, vendors have tried and failed to push high-tech watches every few years. I personally think the watch space and the larger invisible space hasn't been exploited properly beyond the core feature of telling time. Here's why.

The latest advance in theory comes to us from Michigan Tech, which says it can now cloak objects in the infrared spectrum. Previous attempts using metallic metamaterials could only bend microwave radiation, the study claims, but using tiny resonators made of chalcogenide glass arranged in spokes around the object (see diagram at left) researcher Elena Semouchkina and colleagues successfully hid a simulated metal cylinder from 3.5 terahertz waves. While it's hard to say when we might see similar solutions for visible light, even a practical application of infrared cloaking could put your night vision goggles to shame, or perhaps block covert objects from being detected by those newfangled terahertz x-rays.

Apple wants to do that for buttons, too. Cupertino's latest patent application is for pressure-sensitive, capacitive touchscreen materials it could build right into the surface of its aluminum-clad devices, and identify with laser-cut, micro-perforated holes that let light shine from within. According to the filing, the technology could potentially be used to eliminate existing buttons in favor of a smooth, solid slab, and / or integrate new ones into surfaces that weren't previously considered for use. Engineers imagine light-up controls on a laptop's lid that could be used while closed for things like USB charging and media playback, and local heat and sound sensors that selectively light up interface opportunities when users are in close proximity. Not bad, Apple. As long as you let us keep our nice, springy keyboards, we're all for revolutionizing the rest of modern input.

Keeping up with the times, scientists investigating potential methods for rendering physical objects invisible to the human eye have now moved to the full three-dimensional realm. The Karlsruhe Institute of Technology has developed a photonic metamaterial that can make things disappear when viewed from all angles, advancing from previous light refraction methods that only worked in 2D. It sounds similar to what Berkeley researchers developed not too long ago, and just like Berkeley's findings, this is a method that's still at a very early stage of development and can only cover one micrometer-tall bumps. Theoretically unlimited, the so-called carpet cloak could eventually be expanded to "hide a house," but then who's to say we'll even be living in houses by that time?

It's latest aural innovation was tucked quietly away within its booth, disguised as an advertorial for the show itself. Essentially, the banner you're peering at above is a one millimeter thick speaker that's made from cloth, and it definitely has the potential to revolution billboards and possibly even portable media devices. As you can clearly hear in the video just past the break, the flat sound waves emitted from the cloth cannot be heard unless you're standing directly in front of it; even separate audio files playing back just a few feet away didn't overlap with what we heard coming directly at us. There's no telling if Yamaha will ever take this public, but if it does, there are about forty billion ad agencies in the greater New York area that would like to speak to it.

Miruko is the creepiest gaming device we've seen in a while -- but it's also downright awesome. A robotic interface boasting WiFi and a built-in camera, it's designed to be worn and used in augmented reality, real life gaming situations, able to detect things -- like monsters -- that are invisible to the human eye. Once the robot detects the presence of said monster (or zombie), it fixes its gaze on the object, allowing the gamer to follow its line of sight and then.. you know, destroy it -- using an iPhone camera. It's also capable of locating and locking in on specific objects and faces, making it really useful in hunting down whatever imaginary creatures that have been following you lately. Check the coolness in the video after the break, but keep in mind -- we've been able to see the invisible monsters all along.

The ever-evolving tale of the invisibility cloak makes us want to hang our heads in our hands sometimes, so fraught with frustrations does it seem. Well, another chapter's been added to the tome: researchers at the Hong Kong University of Science and Technology have devised a way to extend the invisibility principle, allowing an illusion to sit in place of the invisible object. So, say you wanted to use an invisibility cloak to mask the presence of your bottle of beer on the table, the new concept -- or 'shroud of lies' as we call it -- would enable you to make it appear that there was a glass of water sitting there, in place of the beer. So how does that work, exactly? Normal, every day invisibility cloaks bend light around a central cavity, whereas the team has now worked out mathematical rules for bending light in other ways, allowing a material to be designed to bend light in the exact way a spoon would, so that the light hitting the material would distort, making it look like a spoon was there. Theoretically, all of this is rather simple and quite sound, though it turns out that there are numberless mechanical obstacles standing in the way of producing such devices. The new illusion-producing device would have to be capable of working without interfering with the invisibility cloak itself (which, if you recall, also can't properly be said to exist). There's no word on when any of this will ever come to fruition of course, but we remain always hopeful.

First we hear that Li-ion cells are set to magically double in capacity, and now we're learning that a new form of invisibility cloak is totally gearing up for its Target debut. As the seemingly endless quest to bend light in such a way as to create a sheath of invisibility continues, the University of Illinois at Urbana-Champaign's Nicholas Fang has reportedly developed a metamaterial that acts as a type of acoustic superlens. In theory, at least, this approach would rely on phreaking with sound rather than light in order to intensely focus ultrasound waves; by doing so, one could hypothetically "hide ships from sonar." To be fair, this all sounds entirely more believable than hiding massive vessels from human sight, but we're still not taking our skeptic hat off until we see (er, don't see?) a little proof.

Hate to say it, but we're beyond the point of hope here. We just won't ever, ever see a real-deal invisibility cloak during our relatively brief stint on Earth. That said, researchers at Purdue University are doing their best to prove us wrong, recently developing a new approach to cloaking that is supposedly "simple to manufacture." Unlike traditional invisibility cloaks, which rely on exotic metamaterials that demand complex nanofabrication, this version utilizes a far simpler design based on a tapered optical waveguide. A report from the institution asserts that the team was able to "cloak an area 100 times larger than the wavelengths of light shined by a laser into the device," but for obvious reasons, it's impossible to actually show us it happened. Regardless, for the sake of the kiddos above, we're hoping this stuff gets commercialized, and soon.

Inspired by the ideas of theoretical physicist John Pendry at Imperial College, London, two separate groups of researchers from Cornell University and UC Berkeley claim to have prototyped their own cloaking devices. Both work essentially the same way: the object is hidden by mirrors that look entirely flat thanks to tiny silicon nanopillars that steer reflected light in such a way to create the illusion. It gets a bit technical, sure, but hopefully from at least one of these projects we'll get a video presentation that's sure to make us downright giddy.

The crew at Technologizer was able to listen to a sneak preview of the startup's Edge Motion technology, and if the demo is indicative of the end result, we could be onto something special. Much like NXT's SoundVu tech that seemed to fizzle out about as quickly as it hit the scene in 2005, this system creates a so-called invisible speaker by "using arrays of motors to wiggle the edges of a clear membrane." Gurus at the company are hoping to have it integrated into panels of TVs by the end of this year, though it'll be a bit longer before the same can happen on space-constrained laptops.

Most recently, a new metamaterial made from over 10,000 individual pieces of fiberglass has been used to cloak a bump on a flat mirrored surface -- the material prevents microwaves from being scattered, giving the RADAR (we're guessing it's a RADAR) the impression that the surface is flat. This has many possible applications, such as cloaking sources of interference to cellular communications. Unfortunately, the implication we most desire -- rendering us invisible during high society jewel heists -- has yet to become reality.

The prototype disc shown above is 5 inches in diameter and contains around 20,000 nanotube transistors. The researchers suggest the technology could be used for e-paper, smart tags, and artificial skin, as well as an affordable heads-up display that could be put into car windshields. Our suggestion? Couple it with transparent playing cards for the ultimate poker-cheating experience.

Made with transparent oxide film and electrodes on clear glass or plastic circuit boards, the group believes commercial production could begin in 3 to 4 years and could be cheaply manufactured (current backers of RRAM include Fujitsu, Sharp, Samsung and others). They're hopeful the new technology will pave the way for transparent devices such as monitors and televisions. No images of the transparent chip have been published -- but they're not much to look at, anyway.

We're only at the nano scale folks so you'll have to keep those high school fantasies of an invisibility-cloaked romp through the girls' locker room tucked away for now. Still, two teams of US government funded researchers under the direction of Xian Zhanga at UC Berkeley say that they've developed a material which can bend visible light around 3D objects, effectively making them disappear. While similar to the negative refractive properties of materials developed back in 2006, UCB's so-called meta-material is easier to work with and absorbs far less light than those earlier products. As such, the material could scale to the size of invisibility cloaks to hide objects such as tanks or mischievous boy-wizards. However, that day is a long ways off. In the short term, the meta-material will most likely find use in the far less interesting (to consumers, anyway) application of building better microscopes. Hey, Xian, picture of your invisible material or it didn't happen... oh, wait.

Unlike Brickhouse Security, we won't go so far as to call this thing "invisible," but when placed in the ear, all but the most eagle-eyed among us are likely to overlook it. The elaborately named Secret Service Invisible 2-Way Micro Headset comes with an easily hidden wireless transmitter that plugs into any mobile with a 2.5-millimeter audio output. Once rigged up, the wearer can have someone listen in on conversation in a room while also receiving input from said listener. Unfortunately, this likely Jack Bauer-approved gizmo demands a practically ludicrous $649.95, so it looks like we'll be sticking to brute force and walkie talkies here. Check out a demo video after the jump -- but be sure and kill the speakers first, alright?

While not the first bunch to try and mesh invisibility with military equipment, the British Army is reportedly staying busy by "testing technology it claims makes tanks and troops invisible." Apparently, the (previously) uber-secret trials were conducted by the Royal Engineers and scientists from QinetiQ, and if eyewitness reports are to be believed, they were able to "make a vehicle seem to completely disappear." The illusion (read: we're no closer to actual invisibility cloaks) was reportedly created by utilizing "cameras and projectors to beam images captured from the surrounding landscape onto a specially-adapted tank coated with silicon to maximize their reflective qualities," and if things go as planned, these elusive machines could make their way onto the battlefield "within five years." 'Course, it's not like anyone will have visual proof of that, but we suppose that's just the nature of the beast.

Put simply, users who snap pictures of landmarks and MMS them back to the database can receive "an image with extras added to it." Dubbed Spellbinder, the invisible graffiti project uses image-matching algorithms to analyze the image and send back tagged snapshots of the location a user just photographed. Additionally, location projects and "virtual games" are also being looked into, which should thoroughly please both the social networking fanboys and hide-and-seek lovers alike.

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.

Gunnar Dolling and his colleagues at the University of Karlsruhe in Germany have created a metamaterial with layers of silver sandwiching a thin sliver of nonconducting magnesium fluoride on a glass sheet, and once an array of square holes were etched in, his tests showed that the "structure had a negative refractive index of -0.6 for light with a wavelength of 780-nanometers," besting the previous record of 1,400-nanometers. While the scientific babble may not mean much to you, the long and short of it is that this discovery could "lead to further breakthroughs in invisibility cloaks, which could hide objects from the human eye" and make escaping your troubles quite a bit easier. Moreover, the technology could be used in "superlenses" to see details "finer than the wavelength of visible light," but Dolling is reportedly more interested in studying the effects of his discovery than attempting to build any mystical devices, which is probably for the good of mankind, anyway.

Yes, it's been theorized and in development before. But now, what our friends across the pond have only imagined, scientists at an American university have actually built. A group of brainiacs at Duke University have built a device (based on the Imperial College London theory) that can deflect microwave beams so the beams flow around an object almost as if nothing was there, with not too much distortion (but only in two dimensions). In order to do this, the group built a series of concentric circles made up of "metamaterials," or "artificial composites that can be made to interact with electromagnetic waves in ways that natural materials cannot reproduce." Don't get too excited yet, as scientists warn that this is merely a "baby step." The next step is to make the cloak work in three dimensions, and make improve the cloak's effectiveness. And even still, we're a long way off from making something completely disappear from visibility, which "would have to simultaneously interact with all of the wavelengths, or colors, that make up light." said David R. Smith, a member of the research squad. Hey Duke team, if you ever need human test subjects, we'd definitely be willing to volunteer.
