Hasta La Gadget!

This Dragon Skin armor has been knocking about since 2007, but now that piezoelectrics and intelligence have been thrown into the mix we couldn’t stop ourselves from taking a peek at it. The armor’s strength is derived from a reptilian arrangement of overlapping ceramic and titanium composite discs, which simultaneously block incoming rounds and dissipate the impact to a wider area. What’s interesting about the new design is the two piezoelectric sensors attached to each end — one of them transfers a low voltage of power through the armor in the form of vibration, which the other picks up, and the reported energy loss is interpreted as armor degradation. Gnarlier still is the ability of these sensors to generate electricity from bullet impacts, which can then themselves give you an indication of what sort of bullet hit you. Capable of being applied to soldiers and vehicles alike, this could make the real act of soldiering a whole lot more like a video game (minus the whole “infinite respawn” thing), with HUDs showing you how much “shield” you have left. You can see an old(ish) video of the original armor after the break.

Nokia’s no stranger to the patent application process here in the United States, and while we’ve certainly seen some strange ones emanating from its R&D labs, this one looks like something that should be implemented on the double. Explained as a “user interface for controlling an electronic device,” the multitouch solution would essentially allow you to pinch, zoom and rotate objects as usual, but it would also employ an array of pressure sensors in order to give your motions a sense of severity. If executed properly, one could theoretically envision the use of a strong push to simulate a double tap (for example), or as a means to activate a secondary function that generally requires another button press or the use of a ‘Function’ key. Hit the read link for all the mumbo jumbo, but be sure to keep your expectations within check. Or not.

Another season, another Texas Instruments coprocessor for us to wonder about. For what feels like ages now, TI has been pumping out silicon that promises to bring high-def recording capabilities to cellphones, but by and large, most everything has been stuck at VGA or below. Oh sure, we’ve seen our first batch of 12 megapixel cameraphones, but it’s not like those things are replacing DSLRs en masse. Bitterness aside, the OMAP-DM525 coprocessor is supposedly capable of bringing 20 megapixel imaging to handsets along with 720p video recording, while the OMAP-DM515 hits the ceiling at 12 megapixels. Of course, the DM525 won’t actually be ready for volume production until sometime next year, but here’s hoping a sample or two slips out at CES.

Need an excuse to get some cardio into your life? Can’t live without ye old internet? Thanks to Matt Grey and Tom Scott, the answer to your weight loss woes is pictured above. The aptly-titled Webcycle is essentially a sensor-laden fitness bike that requires users to pedal faster in order to snag more throughput. An Ubuntu-based laptop is wired up to an Arduino and an array of sensors that allow more bits and bytes to seep through based on how hard the rider is working. A simple slow pedal is all it takes to load mobile pages and text-heavy sites, but if you’re hoping to actually watch the video after the break, you’ll certainly need to kick things up a notch. Pure brilliance, we say.

[Thanks, Yoda]

Just as it’s starting to seem like MEMS motion sensor technology is gaining more widespread use, we’re now hearing rumblings of activity from the developers of its eventual successor: NEMS (Nano-Electro-Mechanical Systems). To contextualize this discussion (and to give laypeople a shot at understanding), MEMS sensors are the magic behind the Wii MotionPlus as well as a stunning tech demo recently conducted on a Toshiba TG01. The nascent nano version promises even greater sensitivity, and now scientists from TU Delft in the Netherlands claim they have successfully measured the influence of a single electron on an 800nm-long carbon nanowire. Just detecting such an event is a feat in itself, while the ability to measure its effects can be used in a huge range of ways: from transportation and medicine to ultra-sensitive gaming controllers. While accurate comparisons between the Dutch breakthrough and current generation sensors cannot yet be drawn, we can confidently say that this marks an important step toward making our dreams of playing a nanoscale piano a gargantuan reality.
