Lasers May Stabilize Future Electronics
Posted in Electronic Components, Electronics, Lasers & Laser Systems, Medical, News, MDB on Thursday, 24 July 2014
Nearly all electronics require oscillators that create precise frequencies, which have, until now, relied upon quartz crystals to provide a frequency reference, like a tuning fork used to tune a piano. However, future high-end electronics will require references beyond the performance of quartz, say scientists at California Institute of Technology, Pasadena.

FDA Recognizes Two UL Battery Safety Standards for Medical Devices
Posted in Batteries, Electronic Components, Power Supplies, FDA Compliance/Regulatory Affairs, Medical, News, MDB on Wednesday, 23 July 2014
UL (Underwriters Laboratories), Northbrook, IL, announced that the FDA has recognized two UL battery safety standards as consensus standards for medical devices incorporating lithium or nickel-based batteries. The two standards are UL 2054 - Standard for Household and Commercial Batteries, and UL 1642 - Standard for Lithium Batteries (Cells).

Two of Georgia Tech's software-defined, electronically reconfigurable Agile Aperture Antennas (A3) were demonstrated in an aircraft during flight tests. The low-power devices can change beam directions in a thousandth of a second. One device, looking up, maintained a satellite data connection as the aircraft changed headings, banked and rolled, while the other antenna looked down to track electromagnetic emitters on the ground.

New stretchable technologies and soft robotics being explored by engineers at Purdue University, West Lafayette, IN, could lead to innovations such as robots with human-like sensory skin and synthetic muscles, as well as wearable electronics. But to do so, they say, you would need a low-cost, highly stretchable electrical conductor to interconnect sensors and other components.

Permanent Eye Sensor Could Track and Monitor Glaucoma
Posted in Biosensors, Electronic Components, Sensors, Medical, Patient Monitoring, Diagnostics, News, MDB on Wednesday, 25 June 2014
A team of engineers at the University of Washington, Seattle, have designed a low-power sensor that could be placed permanently in a person’s eye to track changes in eye pressure. The sensor would be placed during cataract surgery and would detect pressure changes instantaneously, then transmit the data wirelessly using radio frequency waves, they say.

'Sensing Skin' Detects Damage in Concrete Structures
Posted in Electronics & Computers, Electronic Components, Electronics, Materials, Sensors, Detectors, Test & Measurement, Communications, Semiconductors & ICs, News on Tuesday, 24 June 2014
Researchers from North Carolina State University and the University of Eastern Finland have developed new “sensing skin” technology designed to serve as an early warning system for concrete structures, allowing authorities to respond quickly to damage in everything from nuclear facilities to bridges.

“The sensing skin could be used for a wide range of structures, but the impetus for the work was to help ensure the integrity of critical infrastructure such as nuclear waste storage facilities,” says Dr. Mohammad Pour-Ghaz, an assistant professor of civil, construction and environmental engineering at NC State and co-author of a paper describing the work.

The skin is an electrically conductive coat of paint that can be applied to new or existing structures. The paint can incorporate any number of conductive materials, such as copper, making it relatively inexpensive.

Electrodes are applied around the perimeter of a structure. The sensing skin is then painted onto the structure, over the electrodes. A computer program then runs a small current between two of the electrodes at a time, cycling through a number of possible electrode combinations.

Every time the current runs between two electrodes, a computer monitors and records the electrical potential at all of the electrodes on the structure. This data is then used to calculate the sensing skin’s spatially distributed electrical conductivity. If the skin’s conductivity decreases, that means the structure has cracked or been otherwise damaged.

The researchers have developed a suite of algorithms that allow them to both register damage and to determine where the damage has taken place.
