Scientists create sweat-monitoring underwear, break them in (video)
Biochip bracelets be damned -- nanoengineers at UC San Diego want to put sensors in your skivvies. Researchers have begun prototyping a pair of tighty-whiteys coated with the requisite carbon electrodes to make electrochemical computing a reality, as it turns out the nether regions are a prime place to measure chemicals excreted in one's sweat. Until recently, there was some question whether the enzyme sensor solution would handle the stresses of daily life, so to speak, but these briefs were up to the task -- subjected to a torturous gauntlet of bending and stretching, a treated elastic waistband was still able to adequately measure chemicals as required. Funded by the U.S. Office of Naval Research, project leaders envision "smart underwear" that measures a soldier's sweat for warning signs and automatically trigger an appropriate medical dosage. We think they might be getting a wee bit ahead of themselves, though -- we don't yet know how they handle detergent, let alone a quality color-safe bleach. Video after the break, but don't expect any footage of the underpants actually being worn.
German researchers develop biotech sensor bracelet, disposable blood lab
Biochips -- flexible, disposable plastic circuits that "compute" via chemical reaction -- have been nearing reality for over a decade, but for obvious reasons we don't always pay attention. German research institute Fraunhofer IZM has just convinced us it's high time we did. This week, the organization announced that it's on the verge of creating a lab-on-a-chip that can diagnose deep vein thrombosis from a single drop of blood, as well as a wristband that can measure body temperature, skin moisture and electromagnetic radiation using plastic chips and sensors only micrometers thick. Impressive, yes, but the real news is the production process -- these gadgets can be printed in reels and sheets. The organization imagines the tools will be so cheap they'll be disposable; rather than wait for lab results, worried individuals will just take one out, test and toss to feel confident about their bloodwork, before hopefully going back to their normal lives.
