FCC wants to set aside wireless spectrum for medical body area devices, our hearts are literally aflutter
The FCC has been making a big push towards freeing up the airwaves for medical uses, and it just took one of its biggest steps on that front by proposing to clear space for wireless body area networks. Agency officials want to let devices operate in the 2.36GHz to 2.4GHz space so that patients can stay at home or at least move freely, instead of being fenced in at the hospital or tethered to a bed by wires. Devices would still need the FDA's green light, but they could both let patients go home sooner as well as open the door wider for preventative care. Voting on the proposal takes place May 24, which leaves our tech-minded hearts beating faster -- and if the proposal takes effect, we'll know just how much faster.
Humans wearing radios could form massive wireless networks of the future
Researchers at Queens University in Belfast, Northern Ireland, are studying how to create an infrastructure out of human beings interconnected by wearing sensors, gateways and radios, resulting in a "body-to-body" network. Because human beings are so easy to come by, the networks could potentially be massive as well as high in bandwidth. The team is now studying how human bodies and movement can affect radio signals, and the general operations of body area networks, which aren't new. Concurrent research is being done at Carnegie Mellon to study how thousands of sensors can communicate with each other effectively. Long term, actual functioning body-to-body wireless networks could render cellular base stations unnecessary in heavily populated areas. Of course, that's all well into the future, but hit up the source for more details.
Qualcomm's Peanut challenges ZigBee, Bluetooth for control of your personal area network next year
Perhaps dissatisfied with the glacial pace of Wibree, Qualcomm's working on an ultra-low-power, short-range wireless transfer tech of its own -- it's called Peanut, and executives claim it only needs "fractions of a milliwatt of power" to push data at several megabits per second. Computerworld got the scoop on the new low-power radio at EmTech@MIT 2010, and reports that Qualcomm's had these goobers in the oven since 2006 and is looking to trump the likes of ZigBee and Bluetooth by this time next year. Assuming, of course, the Peanut standard doesn't require a molasses-like committee of its own to attain formal approval.
Sensium wireless digital band-aid begins clinical trials
It hasn't been a year since it was first announced, and now clinical trials have begun for Sensium. Billed as a "digital plaster," the thin patch contains a power source and sensors for monitoring heart rate, temperature, and perspiration -- all of which can then be sent to your doctor via smartphone / PDA. Sure, it might not have the inherent drama of the rack of loud, blinking machines we're used to seeing in ICUs, but on the other hand it is cheap, disposable, and has a battery life of several days. The device is based on the company's AMx semiconductor IP platform for Body Area Networks, so if you work at a hospital or are a supplier for a large medical concern, hit the read link to see if you can get in on the clinical trials. If not, we're sure that Adafruit will figure out how to build one with an Arduino any day now. PR after the break.
Sony Ericsson's motion activated MH907 headset could change things forever (update: or not)
See that? That's the device that will forever change the way you to listen to music. At least that was the promise made in the teaser running up to today's press event. The buttonless MH907 buds are the world's first "Motion Activated" headphones with Sony Ericsson's "SensMe Control" tech: bung them into your ears to automatically start listening to music, remove one bud to pause. The buds are activated by body contact and mimick the way we control sound now. What's cool is that the headphones seem to use your body as an electrical conduit (a Body Area Network) based on this quote from the webinar:"Requires conductive surface to activate the controls - i.e. your ears, hence it won't turn things on in your pocket by just squeezing the ear buds"If so, this is a first consumer application of this technology that we can recall. Available globally this week for any Fast Port equipped phone for just €39. Video fun after the break.Update: SE has further clarified that the technology is capacitive in nature. In other words, removing an ear bud isn't breaking the flow of current between buds (and across your noodle) -- it's destroying the dynamic capacitor formed by the touch of human skin. Right, this is technology we've seen before in capacitive touchscreens and trackpads. %Gallery-73591%
Wearable ECG uses patient's posture for encryption, transmits data over Body Area Network
Though its fun to think of the Body Area Network as another way for cheap employers to get out of paying for properly wiring your workspace, the most obvious uses for this technology would seem to be in the realm of health care. To this end, the National Institute of Information and Communications Technology (NICT) in Japan has developed an ECG that can be worn 24 hours a day, wirelessly transmitting electrocardiographic data as well as measuring changes in body surface temperature and posture. The data can even be transmitted securely using cryptographic keys dynamically generated by the patient's posture and biological data (which are unique to each user). We'll let you guys ponder the cypherpunk ramifications of this technology in the comments -- and be sure to check out the additional pic we have for you after the break.
ETRI's Body Area Network prototype: prints through your body
Besides working on non-exploding batteries and Flexible OLEDs, Korea's ETRI is hard at work on the underlying technology of their Body Area Network (BAN). Yes, that would be the human body area network, like the Bluetooth PAN only much more personal. Really though, it's just another variation of Microsoft's (and someday even Sony's) patented technology which uses the human body as the electrical conduit between devices. So assuming you wanted to print a document from ETRI's prototype wearable above, you just start the job on the device, touch the Touch-And-Play (TAP) enabled printer and voila, out pops your hard copy. Sweet... and creepy, but still pretty sweet. Assuming of course, that ETRI has met their data transfer goals of 1MB/s by now -- otherwise, you'll look pretty silly poking the printer as you strain under the weight of that modest 2.4Kbps data rate achieved last year. Just remember, never confuse the work of Korea's Electronics and Telecommunications Research Institute with the that of the Korea's Advanced Institute of Science and Technology -- no one likes a splitter. Now kick back, grab a sack of wolf nipple chips and check the pics after the break.
