Researchers use graphene to draw energy from flowing water, self-powered micro-robots to follow?
What can't graphene do? The wonder material's been at the heart of a stunning number of technological breakthroughs of late, and now it's adding oil exploration to its long list of achievements. A team of researchers at Rensselaer Polytechnic Institute have discovered that the flow of good old H2O over a sheet of graphene can generate enough electricity to power "tiny sensors" used in tracking down oil deposits. The gang, led by professor Nikhil Koratkar, was able to suck 85 nanowatts of power out of a slab of graphene measuring .03 by .015 millimeters. The little sensors the researchers speak of are pumped into potential oil wells via a stream of water, and are then put to work sniffing out hydrocarbons indicative of hidden pockets of oil and natural gas. Of course, that doesn't have a whole lot of practical application for your average gadget consumer, but Koraktar sees a future filled with tiny water-powered robots and micro-submarines -- we can dig it.
Plick hitches an elastic ride on the DIY robotics train (video)
Man, we hope Gumby's collecting some royalty checks for this one. One part incredible-stretching toy, and one part DIY robotics kit, the Plick project takes the traditional hobbyist approach to brick-building your own bot and slaps a little rubber all around it. The industrial design prototype from Brazilian engineer Gabriel Paciornik combines programmable robotic parts with an elastic wired connection suitable for strapping your mad scientist creations to everyday objects. So, what can you make? The kit packs a variety of sensor-based circles that react to distance and sound, giving your mod-jobs the power of movement and light. It's safe to say this not-for-market toy veers far from LEGO Mindstorms NXT territory -- and that's exactly the point. Far out video demo and its 60s beach music soundtrack after the break.
Navy tests bacteria-powered hydrogen fuel cell, could start monitoring your underwater fight club
Microbial fuel cells aren't exactly new, but microbial fuel cells scouring the ocean floor? Now that's an initiative we can get behind. The Naval Research Laboratory is currently toying around with a so-called Zero Power Ballast Control off the coast of Thailand, presumably looking for treasures dropped from the speedboat of one "Alan Garner." Purportedly, the newfangled hydrogen fuel cell relies on bacteria to provide variable buoyancy, which allows an autonomous ocean sensor to move up and down water columns with little to no effort. Furthermore, it's able to get its energy from microbial metabolism (yeah, we're talking about hot air), and while it's mostly being used to measure things like temperature and pressure, it could be repurposed for more seirous tasks -- like mine detection. There's no clear word yet on when America's Navy will have access to this stuff, but if we had to guess, they've probably be using it behind our backs for the better part of a score.

Bluetooth SIG takes aim at sensor market, adds Apple and Nordic to board of directors
The Bluetooth Special Interest Group (aka Bluetooth SIG) has some fairly grand plans for the future of its wireless technology, and it's now recruited some big players to help get it there. The group announced yesterday that it's added both Apple and Nordic Semiconductor to its board of directors -- companies that it says will help it "drive Bluetooth technology's expansion into platform and sensor markets." In particular, the group is setting its sights on wireless health sensors, which it hopes to finally gain a real foothold in thanks the lower power requirements of the Bluetooth 4.0 standard, and thanks to the experience of Nordic, which has a long history of working with such devices. Full press release is after the break.
NC State builds self-healing structural stress sensor, moves on to other alliterative projects
"Sensor, heal thyself," goes an old saying, and North Carolina State University researchers have given it a new spin. Structural stress monitors can break during, say, an earthquake or explosion: just when you most need information about a building's integrity. So the NCSU crew added a reservoir of ultraviolet-curable resin; if their sensor cracks, the resin flows into the gap, where a UV light hardens it. An infrared light, which does the actual monitoring, then has a complete circuit through which to pass, and voila: stress data flows once more, aiding decision-makers. Obviously we never tire of UV-reactive gadgetry, especially for making safer buildings, and we're doubly glad to see self-healing that doesn't involve the phrase "he's just not that into you." To see the self-repair in action, check the picture after the break, and hit the source link for more info.
Creepy new Air Force camera can identify and track you from far, far away
Sure you can do neat things like unlock your iPhone using facial recognition, but the Air Force has far grander visions for the tech. Specifically it wants a camera that can identify and track possible insurgents at a significant distance (though it's unclear how far we're talking about here) using only a few seconds of footage. It's turned to Photon-X Inc. to develop a sensor that combines spacial measurements, infrared and visible light to create a "bio-signature" that maps not only static facial features but muscle movements that are unique to each individual. The technology could also be used in targeting systems to identify enemy vehicles and integrated into robots to help them navigate and identify objects... or threatening meatbags. The Air Force even foresees law enforcement, banks, and private security firms using the cams to monitor customers and watch for suspicious activity. Similar tools have been created that use software to analyze video feeds, but they can't match the accuracy or range of this "behaviormetric" system. Normally, this is where we'd make some snide reference to Skynet or Big Brother but, honestly, we're too creeped out for jokes.
Apple patent application suggest iPod nano could become even more of a 'fashion accessory'
There's no guarantee that it will show up in the next iPod nano -- or any iPod nano at all, for that matter -- but a newly published patent application has now offered a few more hints about how Apple might make such a device even more wearable. Titled simply, "Environment Sensitive Display Tags," the patent application details how a small, wearable device could use a variety of sensors and inputs (including a camera, microphone, accelerometer -- even a thermometer) to obtain information about its surroundings and translate that into a visual element that's displayed on the screen. So, for instance, the camera could be used to create a background that matches your shirt or jacket, or the accelerometer could be used to make a screen saver react to your movements (like the rain drops illustrated above). All of which, the application suggests, could serve to make the device even more "aesthetically pleasing" as a "fashion accessory." Incidentally, the patent application also noticeably features "Games" as a menu option in some of the illustrations -- which would be new to the current variety of iPod nano -- but there's no mention of it in the actual claims. And, given that it was filed back in November of 2009, the application's authors could well have simply been working on the assumption that games would simply carry over from the previous generation.
European R&D advances 'internet of things,' hastens our Phildickian future
Why can't our refrigerator fire off an urgent email when the milk has gone lumpy? And the toilet paper dispenser warn us it's empty – before we sit down? And when will our microwaves run BitTorrent? EUREKA, the European R&D network, knows how badly you crave networked objects, and rather than mock you, it's moving to help. To that end, it has developed small, inexpensive, battery-powered sensors able to link everything from consumer electronics to environmental monitors to factory robots – creating the much-anticipated "Internet of Things." But unlike the over-hyped RFID, it's technology you'd actually use. Instead of knowing whether your keys are indeed on the RFID reader, the network could gently remind you that you left them in your car, which is now 100 miles away with someone else at the wheel, but, luckily for you, low on gas. Gaze into the so-called future of things with EUREKA's press release, conveniently embedded after the jump.
BrainGate hits 1,000 day mind-control milestone, nearly three years of pointing and clicking
Aspiring Svengalis rejoice! For BrainGate has reached a significant landmark in computational thought-control -- the 4 x 4-mm implantable chip has given a woman with tetraplegia the ability to point and click with her brain for 1,000 days. An article recently published in the Journal of Neural Engineering said the woman, known simply as S3, performed two easy tasks every 24 hours, using her mind to manipulate a cursor with 90 percent accuracy. Each day she was monitored, S3 would post up in front of a computer and continuously command the thing with her thoughts for 10 minutes. Functionality reportedly deteriorated over time, but the paper points to the chip's durability, not sensor-brain incompatibility, as the culprit. Research is currently underway to incorporate BrainGate into advanced prosthetics that could get tetraplegics like S3 up and moving again. Now, how's that for the power of positive thinking?
Microsoft unites with former exec in building a 'smart city' in Portugal
If you want better cities, goes the theory herein, you'll have to start at their very foundations. Steve Lewis, ex-Microsoftie and current CEO of Living PlanIT, has a vision for how to make our cities smarter and more sustainable, and it starts literally at ground level, with the installation of smart sensors into buildings as they're being built. The appeal of his company's ideas has already attracted some tech luminaries as partners, Cisco being among them, and now Microsoft has also been signed up -- to provide the cloud framework required to keep all those sensors talking with its Azure platform. Paredes, a Portuguese municipality, will play host to one of the first such projects, eventually providing homes for nearly a quarter of a million people and costing a staggering €10 billion ($14.1b) to complete. To understand the synergistic benefits of having your life monitored by an omniscient Urban Operating System sentinel, skip past the break for a press release and explanatory video.
US Army to deploy Individual Gunshot Detector, essentially a radar for bullets
Latest in our series of "when video games turn real," here's the US Army's newest addition to the wargadget arsenal. The Individual Gunshot Detector, produced by QinetiQ, is an acoustic monitor attuned to tracking down the source of gunshots just by their sound. It has four sensors to pick up the noise of incoming fire, and its analysis of those sound waves produces a readout on a small display that lets the soldier know where the deadly projectiles originated from. The entire system weighs just under two pounds, and while it may not be much help in an actual firefight -- there's no way to distinguish between friendly and hostile fire -- we imagine it'll be a pretty handy tool to have if assaulted by well hidden enemies. 13,000 IGD units are being shipped out to Afghanistan later this month, with a view to deploying 1,500 each month going forward and an ultimate ambition of networking their data so that when one soldier's detector picks up a gunfire source, his nearby colleagues can be informed as well.
Sensor-laden surfboard collects gnarly statistics, finally quantifies 'tubular, dude!'
Oh, sure -- it ain't the first time an array of data-collecting sensors have found their way into a surfboard, but the goal with this one is quite different than the one crafted last year at UC San Diego. Tecnalia and Pukas have cooperated in order to build a board with a downright astounding amount of sensors within: there's an embedded PC, gyroscopes, accelerometers, a compass and even GPS, all of which combine to generate a ridiculous amount of data from a ride and its rider. Every ounce of the collected information is stored in a flash memory stick, and after a session is wrapped, all of those bits and bytes are beamed over WiFi to a more potent computer for analysis. The software system to visualize and process the data has been developed in ROS, and with that, researchers can not only judge performance, but also see which techniques were superior. There's a video of the board in action just past the break, but sadly, no pre-order page has emerged just yet. Hint, hint.
Japanese researchers weave capacitive touch into large-area textiles, want to make them wearable (video)
Conductive fibers, yo, they're the future. Japan's AIST is back with yet another quirky idea, this time integrating capacitive touch sensors into 1-micron thick nylon fibers. The results is a big old cloth that can sense your loving touch and inform nearby computers of what you're up to. Initial uses envisioned by the research outfit include implementation in hospitals to monitor bedridden patients, but the ultimate goal is to make this extra-sensitive array a wearable accoutrement. Wouldn't that be lovely?
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%
Health care and aeronautics industries agree that FCC should set aside bandwidth for dedicated remote patient monitoring system
Mobile body area network (MBAN) technology has the potential to be a boon to the healthcare system of the future by enabling remote patient monitoring through disposable wireless devices -- meaning fewer doctor visits for everyone and great news for latrophobes. Until now, MBAN was opposed by the Aerospace & Flight Test Radio Coordinating Council (AFTRCC) because it utilizes the same radio bands that aircraft manufacturers do when they're testing new planes. AFTRCC didn't want all that medical chatter "polluting their spectrum" but decided to get on board with MBAN when the health care industry promised to create a way to stop signals that disrupt aeronautical traffic. MBAN is a part of the FCC's National Broadband Plan and purports to use short-length radio waves (not unlike Bluetooth) in the 2300 and 2400 MHz range to transmit physiological info to treating physicians -- as opposed to other patient monitors that use web-based communications. MBAN would initially be used in hospitals but could later find its way into residential use by employing home entertainment systems (Wii Fit integration, here we come!) to collect and transmit data. With the FCC expected to decide on the final rules for MBAN later this year, the Intel Health Guide may have some company in the at-home patient monitoring business. We can only hope that the next time the aeronautic and health care industries combine forces, it will take the form of jetpack-wearing doctors making house calls.
US Air Force enlists super blimp for Blue Devil surveillance initiative
Way back in September 2009, we reported on an omnipotent war blimp from Lockheed Martin, now it looks like a similar dirigible could be hovering 20,000 feet above Afghanistan by this fall. (It's not clear whether or not the two blimps are one and the same, but Lockheed's craft was slated for an Afghan debut in 2011.) As part of the $211 million Blue Devil initiative, the US Air Force plans to pack the bloated beast -- which sports seven times the carrying capacity of the Goodyear blimp -- with up to a dozen interchangeable sensors and a supercomputer for processing data. It will then hover for stints as long as a week, collecting, assessing, and relaying important surveillance data to ground troops in a matter of seconds. It's a tall order, but Air Force officials hope that an on-board wide-area airborne surveillance system (WAAS), which uses 96 cameras to generate nearly 275TB of data every hour, and a supercomputer hosting the equivalent of 2,000 single-core servers will fit the bill. The aircraft isn't complete quite yet, but barring unforeseen obstacles, like a run-in with a giant needle, it should be up in the air starting October 15th.

iPhone headset socket hijacked to power DIY peripherals (video)
Apple's proprietary dock connector may keep would-be peripheral manufacturers at bay, but if you want to build your own iOS companion devices, there's another way. You might have noticed that the Square credit card reader uses Apple's 3.5mm headset jack to transmit power and data at once, and gadgeteers at the University of Michigan are busy open-sourcing the same technique for all the DIY contraptions you can dream of. Project HiJack has already figured out how to pull 7.4 milliwatts out of a 22kHz audio tone, and built a series of prototype boards (including working EKG, temperature, humidity and motion sensors) that transmit data to and from an iOS app at up to 8.82 kbaud -- using just $2.34 worth of electronic components. See the basic principles at work in the video above, and -- as soon as the team updates Google Code -- find out how to build your own at the links below.
New carbon nanotube aerogel is now the world's lightest solid material
Frozen smoke (read: aerogel) -- not to be confused with the stuff your Grandma uses to flavor her turkey -- is the world's lightest solid material, and it just keeps getting lighter. Researchers at the University of Central Florida have created a new form of the super material, known as multi-walled carbon nanotube (MWCNT) aerogel, that has a density of just four milligrams per cubic centimeter and can be used in sensors to detect pollutants and toxic substances, chemical reactors, and electronic components. Aerogels, which are known as the world's most effective insulators, have been around since the early 20th century, but most of these are fabricated from silicon dioxide. In order to produce the new aerogel, researchers removed the liquid from a "wet gel of well-dispersed pristine MWCNTs," creating a honeycomb structure with walls just 100-nanometers thick. The resulting material is an impressive and resilient electrical conductor that looks and acts less like frozen smoke and more like a burnt marshmallow. And now, you know. Check out the coverage link below for video.
Pioneer engineers Android-powered cyclocomputer, might remind Landis to stop doping
Think Android has reached its limit when it comes to applications? Think again. Pioneer has conjured up a new cyclocomputer, and compared to the antediluvian rivals available on the market today, this one looks like a bona fide supercomputer. It's designed for mounting on the bike's handlebars, where riders can then see speed, cadence, heart rate, and power at a glance. The device is engineered to play nice with the ANT+ wireless specification, and it can also pull data from optional crank sensors that can be installed to monitor one's pedaling force. Furthermore, it's equipped with GPS, and we're guessing it's a prime candidate for running Google's own My Tracks app. There's no time table for release, but we're guessing the International Cycling Union will have one out in no time... one that continuously tests riders for illicit substances, of course. Video's after the break, if you're down for more.
DARPA's MSEE to develop new mathematical language, race of sentient machines
The hyper-ambitious folks at DARPA are totally over the current state of military data collection, and they're pretty sure they know how to fix it: teach sensors how to think. Well, they've got an idea how to fix it, but they've put out a call for mathematician to do the dirty work. The Mathematics of Sensing, Exploitation, and Execution (MSEE) program seeks a unified mathematical language that cane teach sensors not only to collect data, but to interpret, and act on it too. The aim is to eliminate the "data deluge" that comes from ever-increasing streams of information, like cellphone intercepts and video drone feeds, allowing analysts to focus on the important stuff. Currently the onus falls on humans to interpret the overwhelming amount of information collected by military sensors, but DARPA is confident that the right algorithm could have machines interpreting the world as early as 2014. Which gives you right around three years to fulfill every fantasy you've ever had.
