Sensor

Sensors sprinkled throughout the home beam information at a set frequency. Wiring wrapped ...

Smart homes of the future will automatically adapt to their surroundings using an array of sensors to record everything from the building’s temperature and humidity to the light level and air quality. One hurdle impeding the development of such intelligent homes is the fact that existing technology is still power hungry and today’s wireless devices either transmit a signal only several feet, or consume so much energy they need frequent battery replacements. Researchers have now developed sensors that run on extremely low power thanks to using a home’s electrical wiring as a giant antenna to transmit information.  Read More

The LiveRider mount and wireless receiving dongle

The popularity of Apple’s iPhone and iPod touch hasn’t just resulted in an explosion of apps available from the iTunes Store, it’s also spawned a stack of hardware accessories designed to extend the capabilities of said devices. Most common are the seemingly endless array of docks, or cases that increase the devices’ battery life. New Potato Technologies has decided for something a bit different with its LiveRider – a bike mounting system that turns your iPhone/iPod touch into a wireless cycling computer.  Read More

Today's automobiles are jam-packed with numerous sensors and warning systems to help drivers stay safe. Much of the feedback from such systems is provided visually, but there's so much going on that drivers may well be approaching overload. Researchers from Yale's School of Engineering have opted for a different mode of physical stimulus by installing tiny vibrating motors inside a driver's seat to advise of the approach of other vehicles.  Read More

Non-contact sensors monitor patient heartbeats from a meter away

When rest is important to a patient, being rigged up to a heart monitor or disrupted whilst they sleep and having a cold stethoscope placed on their chest isn’t ideal. To get around this problem, a team of scientists at the University of Sussex, UK have successfully developed sensors that are able to detect a heartbeat up to a meter away. The Electric Potential Sensors (EPS) are the world’s first electrical sensors able to monitor heartbeats accurately whilst patients relax in their bed, or rest at home. This breakthrough device gives medical teams and health workers the chance to administer patient-friendly monitoring with minimum impact on mobility or personal space.  Read More

The sensor uses maglev to analyze sample density

When one thinks of magnetic levitation, or maglev, one generally thinks of insanely fast floating trains or possibly even levitating cans and bottles. Well, scientists are reporting the development of a new use for the technology as an inexpensive sensor for analyzing food, water and other beverages.  Read More

Glucose molecules such as this can cause serious problems for diabetes sufferers

Diabetes is an enormous global problem... and it is on the rise. Despite decades of research and advances in technology, the methods of accurately measuring glucose in the body are still quite primitive. A new type of blood glucose monitor being developed at MIT could not only eliminate the need for finger pricks, but could also offer more accurate readings by way of a “tattoo” of nanoparticles injected below the skin.  Read More

3R's A200 is a microscope in your pocket

At the Printable Electronics Exhibition in Tokyo, 3R Systems was showing off their newest model of pocket microscope, the A200. Unlike the previous Vitiny model, which shot at 300,000 pixels, the A200 has a 2 megapixel (2,000,000) CMOS sensor and kicks out images of about 1600 x 1200 pixels.  Read More

A diagram illustrating how the Cell-All system would work

Our smartphones can already surf the Net, take photos and videos, play games, and even make phone calls, so why not... have them smell the air? That what America’s Homeland Security Science and Technology Directorate would like to see happen. The Cell-All initiative would see cell phones equipped with a sensor capable of detecting deadly chemicals. In the event of a terrorist chemical attack, the device could conceivably save numerous lives.  Read More

The tiny 0.3MP Mini Digi camera fits on your keyring

Japanese manufacturer Green House has just released one of the most compact cameras you're ever likely to see. But you'll have to get in really close because the Mini Digi is so tiny that you might just miss it! Amazingly, it measures 2.5 x 1.8 x 1.2 inches, and weighs just under an ounce. So, for photographers who don't want to take their hefty DSLRs with them all the time, attaching a Mini Digi to your keychain could be a fun alternative.  Read More

AwareFashion shirt, with in-built electronics, has cuffs that illuminate when it detects a...

The days of the silence being broken during a live theater performance by some ridiculous ringtone buried inside an inaccessible handbag or jacket pocket may be as long-gone as the “brick phone” thanks to this smart-shirt for theater ushers. Designed by Richard Etter, the special shirt called AwareFashion detects mobile communications devices in its vicinity that haven’t been switched off.  Read More
