Sensors can detect disease markers in breath
A small, thin square of an organic plastic that can detect disease markers in breath or toxins in a building's air could soon be the basis of portable, disposable sensor devices. By riddling the thin plastic films with pores, University of Illinois researchers made the devices sensitive enough to detect at levels that are far too low to smell, yet are important to human health.
3D fingerprint identification system adopts recovery and matching tech
The research team of The Hong Kong Polytechnic University (PolyU) has developed a system for 3D fingerprint identification by adopting ground breaking 3D fingerprint minutiae recovery and matching technology, pushing contactless biometric technology into a new realm of speed and accuracy for use in identification, crime investigation, immigration control, security of access and forensic applications at an affordable cost.
Biometrics: the smartphone wave is reshuffling the cards
The evolution of the smartphone industry since ten years offers to biometric technologies a huge opportunity to install sensors on each human. Today biometrics technologies are rapidly integrated and evolve quickly.
Retractable touch pen compatible with both iOS and Android
The official shipment of Genius' retractable touch pen has been announced. The GP-B200 and GP-B200A are compatible with both iOS and Android-based smartphone devices. For the rest of this announcement, GP-B200 will be used to refer to both models.
The evolution of catalytic nanoparticles in 3D
Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory used a high-resolution electron microscope to study nanoscale details of catalytic particles made of nickel and cobalt-inexpensive alternatives to the costly platinum used in most fuel cells today. A paper describing the research in the journalNature Communicationsincludes 3D, dynamic images that reveal how the particles' external and internal structure and chemica...
Flexible fingerprint sensor to be showcased at TRUSTECH
A 500dpi flexible fingerprint sensor in a smart card form factor designed by FlexEnable is going to be showcased at TRUSTECH 2016 in Cannes, 29thNovember-1stDecember 2016. With biometric authentication becoming increasingly important for the smartcard industry, flexible fingerprint sensors open up new opportunities.
Indoor mobile locator ensures user privacy
Rice University computer scientists have created a system for mobile users to quickly determine their location indoors without communicating with the cloud, networks or other devices. The battery-saving scheme uses image recognition and "hashing," a method that reduces key details in a photo to short strings of numbers called hashes. To determine a location, the system hashes a photo from the user's camera and compares it against a pre-downloaded...
"To go where no map has gone before"
A 3D sky-mapping project that will measure the light of millions of galaxies has received formal approval from the U.S. Department of Energy to move forward with construction. Installation of the project, called DESI (Dark Energy Spectroscopic Instrument), is set to begin next year at the Nicholas U. Mayall 4m telescope at Kitt Peak National Observatory near Tucson, Ariz., with observations starting up in January 2019.
Black opaque conformal coating enhances PCB security
The Dymax Multi-Cure 9451 is a true black and opaque conformal coating from Intertronics that enhances security of electronic products by covering the printed circuit board and components, hiding them from visual inspection. This is an effective barrier to loss of confidentiality and possible copying or reverse engineering of proprietary designs, in addition to its ability to improve circuit reliability in harsh conditions.
Imaging technique slices materials with X-ray
Researchers at the U.S. Department of Energy's Brookhaven National Laboratory have created an imaging technique that allows scientists to probe the internal makeup of a battery during charging and discharging using different x-ray energies while rotating the battery cell. The technique produces a 3D chemical map and lets the scientists track chemical reactions in the battery over time in working conditions. Their work is published in Nature Commu...
