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]
