Cityzen smart shirt tracks your health, recharges during washing

By
Rightly or wrongly, the French are known for clothing designs that are often less than practical. Now, however, French company Cityzen Sciences has won the CES 2014 Inclusive Innovation in Everyday Health award for its development of a Smart Sensing fabric woven with integral micro-sensors – these add the practical benefit of monitoring the health and fatigue levels of the wearer.
The Smart Sensing fabric reads body heat, respiration rate, heart rate, and motion through location via GPS. "The fabric can be made into any clothing; gloves, shirts, pants, you name it," said Gilbert Reveillon, Cityzen's international managing director.
The new smart fabric combines sensors, fabric, distributed computation, and a small battery-powered transmitter into a unit that links in real time to a smartphone. The phone runs an app that stores and analyzes data from the fabric, showing if the person wearing the garment is tired, stressed, or in the path of an imminent heart attack. Obvious applications are for people who find themselves in extreme conditions, such as athletes, first responders, and soldiers.
Smart Sensing fabric, which costs perhaps 30 to 40 percent more than ordinary material, can be safely laundered and ironed. Additional sensors can be added to the fabric, as compatible versions are developed. Such information as blood oxygen, tidal volume (the amount of air flowing in and out of the lungs when breathing normally), and perhaps eventually blood glucose levels could make such fabrics vital systems in monitoring people's day-to-day health.
Perhaps the cleverest part of Smart Sensing fabric is still under development. Cityzen is working on a recharging system for the fabric, that receives most of its energy when the clothing is washed. This is a perfect use for a motion-driven recharging system – can you think of a better environment for collecting mechanical energy than a washing machine?
Smart Sensing fabric is expected to reach the commercial market later this year. More information is available in the video below.

Solar car hits U.S. in round-the-world jaunt

By
Last October, the SolarWorld GT solar-powered car set out from Darwin, Australia on a drive around the world. It has since driven 3,001 kilometers (1,865 miles) across Australia, logged 1,947 km (1,210 miles) crossing New Zealand and been shipped across the Pacific Ocean. This Friday, it will embark on the U.S. leg of its journey, as it sets out across America from the University of California, Santa Barbara.   The SolarWorld GT is the result of a collaboration between solar panel manufacturer SolarWorld, and Bochum University of Applied Sciences in Germany. The four-wheeled, two-door, two-seat car gathers solar energy through photovoltaic panels built into its roof, with its solar generator offering a peak performance of 823 watts. Custom hub motors are located in both of the front wheels. The vehicle manages an average speed of 50 km/h (31 mph), with a claimed top speed of 100 km/h (62 mph). In order to demonstrate that solar powered cars needn't be a radical...

Biocomputer, Alternative To Quantum Computers

By
A team of international scientists from Canada, the U.K., Germany, the Netherlands and Sweden announced Friday that they had developed a model biological supercomputer capable of solving complex mathematical problems using far less energy than standard electronic supercomputers. The model “biocomputer,” which is roughly the size of a book, is powered by Adenosine triphosphate (ATP) — dubbed the “molecular unit of currency.” According to description of the device, published in the  Proceedings of the National Academy of Sciences , the biocomputer uses proteins present in all living cells to function. It uses a strategy similar to that of quantum computers, which use qubits — the quantum computing equivalents of bits — to perform “parallel computation,” wherein  computers are able to process information quickly and accurately by performing several calculations simultaneously, rather than sequentially. In the case of the biocomputer, the qubits are replaced with ...

Qualcomm showcases the Snapdragon S4 ahead of Mobile World Congress

By
We’ve already heard about Qualcomm’s latest processor, the Snapdragon S4 , which will be quad-core and utilize LTE. Qualcomm took the time to give us some details ahead of Mobile World Congress. The new SoC now supports up to three cameras (two in the back for 3D and one front-facing), 20-megapixels, and recording video at 1080p (30fps). We can also expect zero shutter lag, 3A processing (autofocus, auto exposure and auto white balance), and improved blink/smile detection, gaze estimation, range finding and image stabilization. Last but not least, it supports gesture detection/control, augmented reality , and computer vision (via Qualcomm’s FastCV). Hit the break for a couple of videos featuring image stabilization and gestures.
