A Ph.D. student at the University of Toronto is using the same transfer paper currently affixing temporary tattoos to kids -- in conjunction with a common screen-printing technique -- to develop a medical sensor that keeps tabs on a person's exertion by monitoring the skin's pH levels.
Similar devices, which are called ion-selective electrodes (ISEs), are already common among athletic trainers and medical researchers to help spot fatigue, dehydration, or even metabolic diseases. But they tend to be bulky and don't stick well to sweaty skin.
The new sensor stays put and doesn't look so, … Read more
Android smartphones make great personal media players, but because of the lock screen, pausing your music can take a few seconds. EasyMute is an Android app that allows you to quickly pause your music by simply putting your hand over the proximity sensor, even when your phone is locked.
Optionally, you can configure easyMute to lower the volume to a preset level. After installing easyMute, just tap the Enable easyMute button to turn it on.
EasyMute works with most Android music players, such as Google Music and even Pandora.
That's it. Keep in mind that, in order for easyMute … Read more
For those wondering why Apple did not include an ambient light sensor in its latest iPod Touch, a purported e-mail exchange between a top executive and a customer -- ahem -- shines some light on the subject.
Apple news site iDownloadBlog posts what it says is a back and forth between Apple Marketing Chief Phil Schiller and a customer talking about the lack of a sensor in Apple's recently released fifth-generation iPod model.
According to Schiller's message, which remains unconfirmed, the device is "just too thin" to fit one:
The ambient light sensor does just what … Read more
You're biking along, minding your own business. You reach an amazing downhill stretch. You pick up speed. You're really cranking along. Oh no! A hippopotamus wanders onto the trail! You swerve and end up faceplanting in the bushes.
Don't fear, your helmet will dial your emergency contacts and give your location. The ICEdot Crash Sensor is a stick-on sensor that mounts onto your helmet. It connects to your smartphone via Bluetooth. When it senses an impact, it sounds an alarm and starts a countdown clock on the crash sensor app. You have a set amount of time to turn it off.… Read more
Old McDonald had a farm. E-I-E-I-O. And on his farm he had a cow with a wireless intravaginal temperature sensor. E-I-E-I-O.
Swiss farmers are helping to test a new system that sends them alerts when their dairy cows are in heat. Stresses and supplements have led to cows showing fewer visual signs of being in heat. That's where technology is stepping in.
The system from Swiss company Anemon consists of a wireless sensor (installed where the sun don't shine) and a transmitter box that attaches to the cow's collar. An accelerometer in the transmitter collects activity data.
When the cow reaches an optimal temperature (also know as "feeling frisky"), the transmitter text messages the farmer to arrange for a bull rendezvous or artificial insemination. … Read more
COLOGNE, Germany -- A decade ago, a cataclysm rocked the photography business as digital image sensors replaced fim.
It turns out that was just the beginning.
At the Photokina show here, it was clear a second wave of change is sweeping through the industry. Cameras produced during the first digital photography revolution looked and worked very similarly to their film precursors, but now designers have begun liberating them from the old constraints.
Three big developments are pushing the changes: a new class of interchangeable-lens cameras, the arrival of smartphones with wireless networking, and the sudden enthusiasm for full-frame sensors for … Read more
A close-up photo shows the Sony brand name on the 8-megapixel sensor at the heart of the camera.
It's not a big surprise: Sony is very competitive with image sensors these days, and former Sony CEO Howard Stringer let slip earlier this year that Sony was supplying camera technology to Apple.
But the iPhone 5 has two cameras, of course. The lesser one, a front-facing camera for videoconferencing … Read more
Intel Capital has invested in a company that provides motion-sensing technology, hinting at possible future user interfaces for personal computing devices.
Grenoble, France-based Movea said this week that it has secured 6.5 million euros (about $7.9 million) in funding from Intel Capital.
"We look forward to...increasing our involvement in the MEMS and motion sensing space in general," said Erik Jorgensen, investment director for Intel Capital, in a statement. "We believe the role MEMS plays in technology, particularly on the mobile side, is going to continue to increase at a rapid pace."
MEMS, or … Read more
If you're not afraid to swallow your technology, you may want to check out new tech cleared by the Food and Drug Administration this week that lets you ingest a digital sensor powered by stomach acid that alerts your doctors about your health and your treatment habits.
The technology consists of a tiny, silicon-based sensor that, at 1mm wide (roughly the size of a grain of sand), can be consumed via pills and pharmaceuticals and pass through the body much like high-fiber food.
According to the developer, Proteus Digital Health, once the sensor is swallowed, stomach fluids that come into contact with it provide enough power to relay a signal that documents exactly when it was taken. This data is transmitted to a battery-powered patch worn on the skin that detects the signal and records the exact time the sensor was swallowed.… Read more
