Purdue University creates 'bass' powered medical implant, knows where it hertz
We've seen all kinds of medical implants over the years, but none that had a musical preference -- until now. Researchers at Purdue University have created a pressure sensitive microelectromechanical system (MEMS) that uses sound waves as an energy source. The proof-of-concept has a vibrating cantilever that's receptive to sound -- or music -- in the 200 - 500Hz frequency spectrum, which is towards the bottom end of the audible range. The subcutaneous implant converts the low-frequency vibrations into energy, and then stores it in a capacitor. Once the cantilever stops vibrating, it sends an electrical charge to a sensor and takes a pressure reading, the result is then transmitted out via radio waves for monitoring purposes. The immediate real world applications include diagnosing and treating incontinence, but we're already wondering if that self-powering mp3 player implant could finally become a reality?
Qualcomm buys Pixtronix to make for better Mirasol displays?
Qualcomm's whipped out some flipping great wadges of cash in order to snap up Pixtronix for its PerfectLight MEMS-based display tech. It reportedly cost between $175 - $200 million and is expected to be merged into the company's super-low power Mirasol-based displays. Compared to the Kyobo eReader we played with at CES, PerfectLight has a wider viewing angle (170 degree), supports full speed video playback and much better RGB modulation. Depending on how successful the marriage is, it could spell the end of the final hurdles that have hampered the widespread adoption of the technology.
IMEC working with holograms, mirrored pixels to prevent 3D movie headaches
Let's face it, 3D movies are amazing but there are times when you'll walk away with a killer headache. A group of researchers at IMEC believes that holographic video might be the best way around this problem and has been working on a means of constructing holographic displays by shining lasers on microelectromechanical systems (MEMS) platforms capable of moving up and down like small, reflective pistons. Here's the cool part: each pixel would have a spring-like mechanism attached to it that could be moved by applying voltage to it. In the first stage of the technology, a laser is bounced off a MEMS-less chip containing an image, the diffracted light interfering to create a 3D picture. From here, the team can adjust the image by replacing pixels with small, mirrored platforms that can alternate their direction to create a moving projection. It gets technical after this, but you can take a gander at the video after the break for a full demo and explanation.
Knowles Electronics Mems Joystick for Samsung Galaxy Tab, Nintendo 3DS hands-on (video)
With gaming on tablets, the visual experience is often top-notch, but the controls are unfamiliar at best -- even inadequate at times. But adding a traditional joystick is impractical, especially when aesthetics is a key selling point for manufacturers. Chicago-based Knowles Electronics has a fairly practical solution, however, and hopes that some manufacturers will adopt its Mems Joystick. At just 1.6mm tall, the joystick is slim enough for a device to maintain a svelte profile, and the 40 microamps it consumes during normal operation is relatively negligible, according to company reps. Tablets are just the start -- Knowles built a series of prototypes to demonstrate a variety of potential applications. We took the joystick for a spin on a Samsung Galaxy Tab 10.1, Motorola Atrix, Nintendo 3DS and a pair of laptops. All of the joystick prototypes connected using Bluetooth or USB, and were designed specifically for this CEATEC demonstration -- sadly they won't be available for purchase, though manufacturers could implement the controller into similar products. It took only a few seconds to get accustomed to the pair of joysticks mounted to the back of the Tab. Controlling gameplay felt natural, and we definitely preferred playing with a clear view of the display. We also navigated through Google Maps, and scrolled a web page -- both experiences felt superior to moving around the touchscreen. The 3DS joystick functioned similarly to the native controller included with that device, though Knowles reps noted that it's significantly smaller, and uses less power -- and without compromise, it seems. Jump past the break for a walkthrough of the devices we saw today, but try not to fall in love -- you won't be able to use the Joystick anytime soon, if manufacturers decide to implement them at all.%Gallery-135902%
Apple is world's second-largest buyer of accelerometers, gyroscopes, microphones
The popularity of Apple's iOS devices propelled the manufacturer to the top of the consumer microelectromechanical system (MEMS) sensors market. The millions of iOS devices in the wild are chock full of 3-axis gyroscopes, accelerometers, microphones and bulk acoustic wave (BAW) duplexers. In 2010, Apple's purchase of these sensor components rose 116.7 percent year over year and climbed to a whopping US$195 million. This figure is only $5 million behind market leader Samsung, which purchased $200 million in MEMS sensors for its mobile phones and tablet devices in 2010. These numbers pushed Apple and Samsung above former leader Nintendo, which ruled the industry when the Wii and the Nintendo DS were at their pinnacle. Apple's influence in the MEMS industry is extensive, according to Jérémie Bouchaud, principal analyst for MEMS at iSuppli. Bouchaud suggests Apple created a new market for these sensors with the original iPhone, which was one of the first handsets to include an accelerometer. Apple also revived the tablet industry, which relies heavily on MEMS sensors, with the debut of the iPad in 2010.
Green Goose sensors monitor your life, you earn experience points (update)
We're pretty certain that once embedded wireless sensors catch on, they'll pervade every aspect of our lives, and Green Goose is building a microcosm of that eventuality in the form of a role-playing game. The five-person SF Bay Area startup has embedded custom 915MHz radios and MEMS accelerometers in a variety of tiny transmitters which you can mount to household objects -- like a water bottle, bicycle, or the toothbrush above -- which report back to the receiver with your actions and thereby increase your score. Brush your teeth on time, take your vitamins, or exercise repeatedly within a couple hundred feet of the receiver, and you'll eventually level up. (Or, optionally, muck with the sensor just right, and it'll register points anyhow.) Presently, that level isn't worth anything, but founder Brian Krejcarek says there are tentative plans to tie these points into a real game and an API to build the idea out, and he's presently looking for partner companies here at the Launch Conference in San Francisco to help roll out the sensors (which cost approximately $4 each) under branded marketing initiatives of some sort. If you don't want to wait, the company will sell starter kits starting February 28th for $24. Not bad for a head start on the future, right? Update: VentureBeat reports that Green Goose raised $100,000 in funding at the conference. Another interesting note: ReadWriteWeb reports that the sensors were originally pitched as a money-saving tool. Update 2: $100,000, not $100 million. Whoops. %Gallery-117463%
Qualcomm lays down $1 billion for new Mirasol plant in Taiwan, catering small and medium devices
Good news, digital bookworms! After months of rumoring, Taiwan's Ministry of Economic Affairs has just announced that Qualcomm will really be building a new Mirasol plant over there. Specifically, the $1 billion, seven-hectare factory will reside in the Hsinchu Longtan Science Park to mass-produce small and medium flavors of said transflective display, meaning the Snapdragon maker will, for the first time, be able to churn out something smaller than the current lone 5.7-inch model. Yep, those must be the low-power smartphone screens that Qualcomm talked about previously, which sure sound delicious. Now, what's up with our little Pixel Qi?
Hitachi's MEMS display: big aspirations in a little prototype
We know the following to be true: microelectromechanical systems (MEMS) technology can foster some very inventive gadgetry, and it's a wonderful four-turn, 45-point Scrabble word (barring special tiles and presuming an abnormally-large board). That said, the MEMS display sector is still quite small and still a ways from reaching the market (hello, Mirasol), which makes every appearance a bit more interesting than the last. Hitachi's little showing caused quite the crowds at its CEATEC booth, with a pair of 2.5-inch QVGA prototypes built using Pixtronix's PerfectLight MEMS display tech within a LCD infrastructure. The color came through on the first screen, and animations was fairly fluid (with the exception of one or two brief moments of lag). The other display on hand was monochrome with a backlight that flickered on and off as a generic desk lamp shone directly onto it. It was still legible enough without the backlight, but it definitely took some straining. Pixtronix is promising 24-bit color depth, 170-degree viewing angles, and a 75 percent power reduction over equivalent LCD displays. As for Hitachi, the company reportedly plans to release displays in the 10-inch and under market by early 2012 -- so yes, in case you were wondering, these'll be back for next CEATEC, too. Enjoy the pictures below, so you have something to look back on. %Gallery-104599%
World's smallest violin uses MEMS, plays only for you (video)
You might not have heard of microelectromechanical systems (MEMS), but there are likely a bunch in your new smartphone -- they make possible the tiny accelerometers and gyroscopes needed to detect motion as your device swings around. However, last week students at the University of Twente demonstrated a brand new micrometer-scale system: a tiny musical instrument that plucks strings (those "folded flexures" above) one-tenth of a human hair wide. Six microscopic resonators fit on a microchip, one resonator per musical tone, and series of the chips can be combined into a MIDI interface to play entire songs. Though the micronium needs to be amplified 10,000 times before they're audible through standard speakers, the instrument's the real deal -- watch it play a wide selection of tunes (including some Mario Bros) in a video after the break. One burning question remains, however: is this nano-violin open source?
Purdue's 'self-calibrating' MEMS could produce the most accurate sensors yet
Micro electromechanical systems, or MEMS, aren't anything new. But Purdue University's Jason Vaughn Clark has ideas that are far grander than those we've seen already. Mr. Clark has purportedly developed a new take on an old spin, with electro micro metrology (EMM) enabling engineers to "account for process variations by determining the precise movement and force that's being applied to, or sensed by, a MEMS device." These self-calibrating machines are the first to do so without any external references, which would allow nanotechnologists, crime forensics researchers and a whole host of others to determine what actually happens at a microscopic level. In theory, the gurus working on this stuff long to improve the accuracy of atomic force microscopes and to eventually create a diminutive AFM-on-a-chip, which -- according to Clark -- could "open the door to the nanoworld to a much larger number of groups or individuals." We're waiting.
iFixit and Chipworks teardown the iPhone 4's gyroscope
You didn't think the folks at iFixit would simply teardown the iPhone 4 and call it a day, did you? They've now gone the extra mile and done a detailed teardown of the iPhone 4's gyroscope with a little help from Chipworks. That's of course a MEMS (or microelectromechanical system) gyroscope and, according to Chipworks, nearly identical to an off-the-shelf STMicroelectronics L3G4200D gyroscope, which is actually what they used for the teardown. What's more, they also went even further and put another gyroscope (not used in the iPhone 4) under an electron microscope just to illustrate how incredibly complex and minute the structure of MEMS gyroscopes are. Head on past the break for a glimpse of that, and hit up the link below for the complete teardown.
Arterial tandem: coronary drill gets cleared for use, MEMS sensor distinguishes between kinds of plaque
We know discussing things involving "arteries" and "coronary plaque" generally don't do much for one's appetite, but being the holidays and all, we honestly can't think of a more fitting way to remind you not to pig out this evening. Up first is a MEMS-based sensor designed by downright enlightened researchers at the University of Southern California, which is used to "distinguish between stable and unstable atherosclerotic plaques in coronary arteries." The idea here is to more easily determine whether a patient needs immediate surgery or simple lifestyle changes in order to remedy artery issues, though the process is still awaiting clinical approval before it can be used en masse. In related news, Pathway Medical has just received European clearance to sell its Jetstream G2 NXT coronary drill overseas (or "peripheral atherectomy catheter," as it were), which does exactly what you'd expect it to: clear clogged blood vessels in the treatment of PAD. If you're not already grossed out, feel free to tap the links below for more information on head past the break for a couple of video demonstrations. Mmm, honey ham!
STMicroelectronics' 3-axis MEMS gyroscope gives a new level of control to your mobile
Man, talk about timely. We heard right around 11 months ago that MEMS gyroscopes would be hitting an array of handsets in 2009, and while it's looking like that estimate will be just a touch off, you won't catch us kvetching with "early 2010." STMicroelectronics has just announced its new 3-axis MEMS gyroscope, which promises 360 degree "angular-rate detection for high-precision 3D gesture and motion recognition in mobile phones, game controllers, personal navigation systems and other portable devices." The gyro is said to provide two separate outputs for each of the three axes at the same time: a 400dps full-scale value for slow motion, and a 1,600dps full-scale value to detect and measure speedy gestures and movements. We're told that samples of the tech are available now with mass production scheduled for Q1 2010; and yeah PSP, it's totally cool if you keep sweating. NGage is about to be back... with a vengeance!

Samsung and Uni-Pixel team up for better, cheaper TMOS displays
Uni-Pixel has developed a new display technology that could succeed LCD and LED displays, and if all goes according to plan we might see something come to market as soon as next year. Opcuity uses one layer of MEMS film in in a TMOS (multiplexed optical shutter) device for results that are said to be ten times brighter and sixty percent cheaper to manufacture than LCDs (which use five layers). Since TMOS displays are very similar to LCDs, existing manufacturing lines can be used -- lowering start-up costs and rescuing older assembly lines in the process. According to the company's CFO, the manufacturing process "subtracts from existing LCD lines--you just need to remove some equipment that is no longer needed." Samsung and Uni-Pixel have teamed up to produce 4-inch displays using the technology, but who knows? Maybe Microsoft Research's interactive office will become a reality sooner than you think.[Via OLED-Info]
Mizzou's nuclear battery to power things smaller than your brain can imagine
Oh yeah, everyone loves the extended battery, but are we really kosher with the added bulge? A team of boffins at the University of Missouri certainly aren't, as they've spent the last good while of their lives researching and developing a new nuclear battery that could be used to power devices much smaller than, well, most anything. The radioisotope cell, as it's called, can reportedly "provide power density that is six orders of magnitude higher than chemical batteries," and while some may question the safety of this potentially volatile device, the liquid semiconductor (used instead of a solid semiconductor) should help ease concerns. The current iteration of the device is about the size of a penny, and it's intended to power a variety of MEMS systems. Now, if only these guys could find a way to make a standard AA last longer than a week in our Wiimote, we'd be pleased as punch.[Via BBC, thanks Jim]
Funai Eco Scan projector adds multitouch capabilities to your bedroom wall (video)
Here's hoping every pico projector outfit on the planet is paying attention to what's going down at CEATEC, otherwise they can pretty much forget about competing with what Funai is boasting. Seen here in Japan, this prototype projector utilized a Nippon Signal MEMS scanner and a great deal of top-secret technology in order to actually add multitouch capabilities to whatever surface is lucky enough to receive the projected image. You read right -- if you use this PJ to beam up an image on your bathroom wall, school whiteboard or any other surface, you can count on that surface having multitouch capabilities while the image is live. Once projected, users simply twist and turn the image in order to have it modified in real-time, and while there are obviously far more enterprise-based uses for this than consumer-based uses, there's no denying the awesomeness. Have a peek of the beamer in action after the break, and expect it to go commercial sometime in 2010 (if we're lucky).[Via Tech-On!]%Gallery-75060%
NEMS takes step forward, MEMS looking nervously over shoulder
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.
Toshiba TG01 gets third-party motion sensor for large picture viewing, not virtual golf
Looking for a way to further push the Snapdragon processor while constrained with a 4.1-inch screen, the Japanese-based Usuda Research Institute and Systems Corp has tacked on a MEMS motion sensor to Toshiba's T-01A, also known as the TG01, for motion-based navigation around what it's touting is a 2,000-inch picture. According to Nikkei, this "MotionPlus" like adapter has been shown to work alongside the camera, potentially paving the way for some AR application like we've seen with Tegra. It's hard to tell from the videos just how accurate it is, but we'd love to see this go official -- after a few cosmetic improvements, of course. Check out footage of the dongle in action after the break.[Via WMPoweruser]
InvenSense gloats about world's first 6-axis MEMS-based motion sensing solution
We tell ya, some proud folks work at InvenSense. After boasting last year about its Wii MotionPlus-powering IDG-600 motion sensor, the company is set to gloat once more at E3 this year. The cause for celebration? Its 6-axis motion processing solution, which it's calling a world's first. Said solution weds its IME-3000 3-axis accelerometer with its IDG dual-axis family of gyros in order to produce a wicked small 6-axis motion sensor. In theory, at least, this creation is small enough to add MotionPlus-like capabilities to smartphones and other ridiculously small devices, with even TV remotes holding the promise of one day letting you "roll through" the EPG. Currently, the only big-name devices utilizing 5- or 6-axis motion functionality is Logitech's MX Air Mouse and the aforementioned MotionPlus accessory, but obviously InvenSense is hungry for more. Too bad that DSi already launched, right?
Samsung's MEMS shutter could massively improve high megapixel cameraphones
We won't go so far as to say that SE and LG are waiting for this here technology to go commercial -- after all, we're still years (at best) away from that -- but considering that the ninth iteration of your favorite smartphone is likely destined to boast a 453 megapixel camera, we're thrilled to see someone working to make those captures worth looking at. Over in Japan, Sammy is teasing a new MEMS shutter that measures just 2.2 millimeters in diameter and would essentially allow cameraphones to grab blur-free images even with ultra-high megapixel sensors. Feel free to dive into the read link if you're into technobabble; otherwise, just be sure to pay attention in around a decade when this stuff actually has a bearing on your life.
