Pop-up sensor would give robot surgeons a sense of touch

Robotic surgery is no longer the stuff of science fiction. However, these robots can’t really feel their way around — the need for super-small mechanisms rules out existing approaches to touch. That’s where Harvard researchers might come to save the day. They’ve developed a pop-up sensor whose four layers collapse to a tiny footprint (just a tenth of an inch) when necessary, but expand into a 3D sensor thanks to a built-in spring. The design is extremely sensitive, too, with a light intensity sensor that can detected mere millinewtons of force. Source: Harvard University , IEEE Sensors Journal

This Sensor Will Give Your Phone a 1080p, 60fps Front Camera

Most front-facing phone cameras suck. It’s not their fault, though: they have to be squeezed in to a tiny gap, which puts obvious limits on their geometry. Fortunately, this new Omnivision sensor squeezes a lot more performance into that minuscule frame. Read more…

Wireless ‘under the skin’ prototype implant beams instant blood test read-outs to your smartphone

A new blood-testing subdermal sensor has been developed by a team of scientists in Switzerland. While that may not sound particularly notable, this half-inch prototype can instantly beam several health metrics to smart devices over Bluetooth , monitoring cholesterol, blood sugar levels as well as the impact of medical treatments like chemotherapy using five built-in sensors. The device has already been tested on animals and while the researchers hope to begin testing soon on patients that would typically require a lot of blood tests and monitoring, the module is still several years from a commercial release. According to the EPFL ‘s video, the sensor can even predict heart attacks several hours before they occur, sensing minute changes in the bloodstream ahead of time. We’ve ‘implanted’ the explanation after the break, but if you’re looking for some more medical-minded specifics, head to the source. Filed under: Science , Alt Comments Via: BBC Source: EPFL

MIT ear-powered wireless sensor sustains its charge through sound

You wouldn’t immediately think of the ear’s cochlea as an energy source, but MIT knows that every mammal effectively has a pair of very small power plants because of the ionized environment. School researchers are trying to harness that energy through a new sensor that exploits the whole ear canal system. As eardrum vibrations naturally create a usable voltage from brain signals, the prototype can build enough charge in a capacitor to drive a very low-power wireless transmitter that relays the electrochemical properties of the ear and potentially diagnoses balance or hearing problems. The beauty of the system is its true self-sustainability: once the transmitter has been been jumpstarted with radio waves, it powers itself through the resulting transmissions. Energy use is also sufficiently miserly that the sensor doesn’t interrupt hearing. Work is still early enough that there’s a long way to go before such implants are part of any treatments, but there’s hope that future chip iterations could help fix inner ear maladies, not just report on them. Something tells us, however, that the doctor won’t ask us to take two dubstep tracks and call back in the morning.
