Ultrasensitive Chip-Based Sensors
An optical whispering gallery mode resonator was developed that can spin light around the circumference of a tiny sphere millions of times, creating an ultrasensitive, microchip-based sensor for multiple applications.
Briefs: Electronics & Computers
Pressure sensors play an important role in engine maintenance and monitoring systems by diagnosing problems before they happen. To capture the most accurate data, however, these sensors must be...
Briefs: Power
Government infrastructure facilities such as water treatment facilities, power plants, laboratories, and the like may be targets for terrorist attacks. Similarly, oil pipelines, power grids,...
Briefs: Test & Measurement
Pointing precision is a critical element of instrumentation for optical communications and ranging in space, affecting laser design, link power budgets, and SWaP. While star trackers possess pointing...
Briefs: Energy
Existing nanosensor technologies depend on an external power source (typically a battery) to operate. Chemical and biological sensors based on nanowire or nanotube technologies exhibit...
Briefs: Manufacturing & Prototyping
Liquid droplets are used in many applications, from printing ink on paper to creating microcapsules for drug delivery. Inkjet printing is the most common technique used to...

Plasma Generator Using Spiral Conductors
NASA's Langley Research Center has developed a patented SansEC sensor technology for use in many different areas, including tall structures and wind turbines. The SansEC technology is a proven wireless sensing platform capable of measuring the electrical impedance of physical matter in proximity to the...
Briefs: Manufacturing & Prototyping
Jet engines can have up to 25,000 individual parts, making regular maintenance a tedious task that can take more than a month per engine. Many components are located deep inside...
Briefs: Mechanical & Fluid Systems
A novel foot-pedal-operated system and device were developed to control translational and rotational movement of an object in three-dimensional (3D) space. The Foot Pedal Controller system enables operators to control...
Briefs: Sensors/Data Acquisition
For patients missing a hand, one of the biggest challenges to regaining a high level of function is the inability to rotate one's wrist (pronate and supinate). These are essential movements...
Briefs: Imaging
Engineers at Duke University have developed a way to extract a sequence of images from light scattered through a mostly opaque material — or even off a wall — from one long...
Briefs: Imaging
A new method of X-ray scanning will allow for the visualization of many more biological molecules, providing critical information about what is inside molecules to scientists who...
Briefs: Nanotechnology
Ultrashort optical pulses are becoming more and more relevant in a number of applications including distance measurement, molecular fingerprinting and ultrafast sampling. Many...
Briefs: Medical
Researchers have developed a new ultrasound transducer that could dramatically lower the cost of ultrasound scanners to as little as $100. Conventional ultrasound scanners use piezoelectric crystals to...
