Portable fat breathalyzer indicates if you’re burning fat

By - July 25, 2013
While there's no shortage of breathalyzers capable of detecting if you’ve had one too many drinks, a prototype device developed by researchers at NTT DOCOMO Research Laboratories analyzes your breath to detect if your body is burning fat. Besides letting users know if that exercise regime is actually shedding some pounds, its creators say the portable sensor could be helpful for diabetics and those trying to lose weight manage their daily diet.

Piezo-resistive fibers enable "blood pressure watch" with continuous monitoring

By - June 13, 2013
Blood pressure is one of the main vital signs, measuring the pressure of the blood upon the walls of blood vessels as it is pumped around the body by the heart. High blood pressure, or hypertension, places increased stress on the heart and can be an indicator of other potentially fatal health problems, such as stroke, heart attack, and heart failure. Most people will have had their blood pressure tested using a sphygmomanometer on a visit to the doctor, but a new wristband device is set to provide a more convenient and continuous way to keep a watch for signs of trouble.

Graphene-based image sensor to enhance low-light photography

By - May 30, 2013 4 Pictures
A team of scientists at Nanyang Technological University (NTU) in Singapore has developed a new image sensor from graphene that promises to improve the quality of images captured in low light conditions. In tests, NTU claims it has proved to be 1,000 times more sensitive to light than existing complementary metal-oxide-semiconductor (CMOS) or charge-coupled device (CCD) camera sensors in addition to operating at much lower voltages, consequently using 10 times less energy.

Tiny, personal blood testing laboratory gets under your skin

By - March 19, 2013 7 Pictures
Blood tests usually involve drawing some blood out of the body. Now scientists from the Ecole Polytechnique Fédérale de Lausanne (EPFL) have developed an implant that allows blood to be analyzed from within the body, with results then transmitted wirelessly to a computer. While still at the experimental stage, the device could make it easier for health care providers to monitor the chronically ill and provide more personalized treatment to cancer patients. Read More

SMARTwobble objectively measures improvements in balance

By - January 30, 2013
With the notable exception of the Wii Balance Board introduced with Wii Fit in 2007, balance and wobble boards generally aren’t the most technological pieces of equipment. Dr Jonathan Williams, a physiotherapy lecturer at Bournemouth University in the U.K. has added sensors and wireless technology to the humble wobbleboard to objectively measure improvements in patients’ balance.

Tattoo-based medical sensor puts a happy face on detecting metabolic problems

By - December 5, 2012
Next time you see an adult with a stick-on tattoo, don’t laugh – that person might have a metabolic problem, or they could be a high-performing athlete who’s getting their training schedule fine-tuned. No, really. A team lead by Dr. Joseph Wang at the University of California, San Diego, has created a thin, flexible metabolic sensor that is applied to the skin ... and it takes the form of a smiley-face tattoo.
