Akustica intros AKU2103 HD microphone for laptops
Akustica, which makes its mark building acoustic system-on-chip solutions, has recently introduced what it calls the "world's first HD microphone that enables HD voice quality in laptop PCs and other broadband mobile devices." The firm's AKU2103 is a digital-output microphone with a "guaranteed wideband frequency response," which means that you can sleep easy knowing that your built-in mic complies with the TIA-920 audio performance requirement for wideband transmission. This MEMS device crams the mechanical transducer, output amplifier, and sigma-delta converter onto a single chip of silicon, and touts near-immunity to RF and electromagnetic interference as well as to power supply modulation. The surface-mountable unit measures in at just four- x four-millimeters in size, and while pricing details aren't available to the masses just yet, Akustica plans on sampling the AKU2103 in Q3 of this year.

Water reactive sheets could become critical part of MEMS
While we've seen mention (and patent applications) of origami-based gadgetry before, the latest gizmo to incorporate crafty folding also melds it with a water reactive plastic in order to create diminutive shapes that "could be used to make certain microscopic 3D structures in large quantities." Gurus from ESPCI and the Paris Institute of Technology have teamed up to concoct specialized plastic sheets which react in curious ways to wee water droplets, and while the process itself seems more interesting than useful, the bigger picture could enable this technology to become a staple of microelectromechanical systems used in printing heads and video displays. Interestingly enough, the scientists were even kind enough to create a time lapse video of the morphing process in action, so be sure to tag the links below if you're even remotely interested in seeing a two-dimensional triangle mystically convert into a pyramid.[Via NewScientistTech]
Autonomous robotic fleas could create distributed sensor network
We've seen a fair bit of mesh networking approaches lately, and thanks to a unusual project going on at the University of California, Berkeley, the next great ad hoc network could be started by a horde of bugs. Sarah Bergbreiter has developed an "autonomous robotic flea has been developed that is capable of jumping nearly 30 times its height," thanks to what could possibly be hailed as the "world's smallest rubber band." Interestingly, the creator hopes that the minuscule bugs could eventually be used to "create networks of distributed sensors for detecting chemicals or for military-surveillance purposes." The Smart Dust initiative could eventually be expanded to grow wings, but for now the solar-powered bugger will stick to hoppin' via a "microcontroller to govern its behavior and a series of micro electromechanical systems (MEMS) motors on a silicon substrate."[Via BoingBoing]
NanoPass needles set to vaccinate sans pain
Given the choice, even we'd take the pills over the vaccination, but a new Israeli startup is hoping to ease the fears so commonly associated with needles. NanoPass Technologies is working to develop its "proprietary intradermal drug delivery technology," which supposedly deliver injections without the painful side effects by actually not reaching the nerve endings of the skin. Based on MicroPyramids, which are manufactured by MEMS (Micro Electro Mechanical Systems), the pure silicone crystals are used in extremely diminutive microneedles for intradermal injections, and the tip of the device measures less than one-micrometer in diameter. The company touts its pain-free technology (sound familiar?) as a breakthrough that is "non-intimitdating," which should reduce the likelihood of fainting both youngsters (okay, and adults) face when dealing with needles, and is even said to be easier to administer. Unfortunately, we've got no good news proclaiming that these will be replacing intramuscular and subcutaneous methods later this week, but the $6.5 million in funding that the company has acquired should go pretty far is helping its cause.

Researchers craft microscale robotic hand for surgeries
It's no surprise that humans are doing less and less of the dirty work while they simply control robotic creatures that are actually doing the internal repairs, but a UCLA researcher has devised a ridiculously tiny "microhand" to handle even the smallest surgery-related tasks. The hand, which is said to be a "feat of microscale mechanical systems (MEMS)," measures just one millimeter across when closed into a fist, features four "fingers" made of six silicon wafers each, and touts four gas-powered balloons acting as the muscles at the wafers' joints. As you may expect, the gas lines that run to the balloons inflate and deflate the joints, causing the fingers to grasp and release as needed. The primary purpose is to eventually use the technology in new forms of "minimally invasive surgery," and although the microhand is likely years away from practical use, they're already in cahoots with robotic firm to develop a "slightly larger" rendition with an onboard camera for live action video feeds.[Via MedGadget]
InvenSense shrinks gyroscopic chip for cameraphone image stabilization
Soon you may not be able to blame your crappy cameraphone pics on the quality of your handset's imaging equipment, thanks to a tiny new dual-axis gyroscope built using MEMS technology that will be employed for image stabilization on future, multi-megapixel phones. Built by San Jose's InvenSense Corp., the IDG-1000 is a single-chip silicon device as small as a baby's fingernail, or five times smaller than competing solutions based on so-called piezo-type technology. Volume shipments of the new chip are scheduled to begin this fall, so don't be surprised if you see one incorporated into Samsung or LG's next entrant into the ongoing battle for cameraphone resolution supremacy.[Via The Raw Feed and EE Times]
