Gyroscopes are devices that help vehicles, drones, and wearable and handheld electronic devices know their orientation in three-dimensional space. Originally, gyroscopes were sets of nested wheels, each spinning...

The global bearings market is expected to grow significantly due to increasing commercial and industrial machinery and manufacturing activity. Bearings are used in virtually...

Many of today's silicon-based electronic components contain 2D materials such as graphene. Incorporating 2D materials like graphene — which is composed of a single-atom-thick layer of carbon atoms...

Typical direct-injection engines, such as diesel engines, can produce soot due to fuel-rich combustion conditions. Filters and catalytic converters are currently used to reduce soot and harmful...

Trained rescue dogs are the best disaster workers — their sensitive noses help them track down people buried by earthquakes or avalanches. But dogs need breaks. A new measuring device is always...

Engineers and software developers are seeking to create technology that lets users touch, grasp, and manipulate virtual objects while feeling like they are actually touching something in...

A process has been developed that enables the production of a 2-mm flat camera. The lens is partitioned into 135 tiny facets, similar to the eyes of an insect. The facetVISION camera is...

Printable metal tags have been developed that could be attached to everyday objects to turn them into “smart” Internet of Things (IoT) devices. The tags are made from...

Medical image registration is a common technique that involves overlaying two images, such as magnetic resonance imaging (MRI) scans, to compare and analyze anatomical differences in great...

Heat treatment, also known as annealing, is a common step in the semiconductor fabrication process. A buildup of radiation-induced localized charge within the...

The first laser based on the wave physics phenomenon called bound states in the continuum (BIC) has been developed. The technology could revolutionize the development of surface...

NASA's Langley Research Center has developed the SHEARLESS composite boom with a final cross-section shape that is lenticular and is flexible enough to...

NASA's Glenn Research Center has developed a novel solid oxide fuel cell (SOFC) with five times the specific power density of currently available SOFCs. This highly efficient SOFC can operate on a...

The detection and localization of gas releases, such as methane from leaking natural gas pipelines or nitrogen oxides from failing electrical equipment, require high sensitivity to the target gas and insensitivity...

It is relatively easy to measure small movements of large objects, but is much more difficult when the moving parts are on the scale of nanometers, or billionths of a meter. The ability to accurately...

Spectrometers are widely used for applications such as chemical analysis, remote sensing, quality control, environmental monitoring, spaceborne measurements, and optical measurements. Most spectrometers...

NASA Langley Research Center has developed a novel optical grating device that dynamically modulates light and is capable of controlling the spectral properties and propagation of light...

The Inductive Non-Contact Position Sensor is a highly accurate sensor for motion control applications. The sensor was designed to monitor the precise movements of an optical inspection system that...

Today's photovoltaic power systems are generally comprised of a single photovoltaic module or multiple modules connected by combinations of series and parallel circuits as a photovoltaic array....

There are challenges involved when using magnetically responsive materials to achieve the one-way flow of light in a photonic chip, including the ability to place compact magnets on a chip. In...

A blue-light imaging method was developed that can be used to obtain visual data from large test fires where high temperatures could disable or destroy conventional electrical and mechanical sensors. The...

Gas turbine blades of conventional rotorcraft turboshaft engines are optimized to operate at nearly a fixed speed and a fixed incidence angle. If the operating condition of the engine changes, then the flow...

Most naturally occurring materials have a disordered atomic structure that interferes with the propagation of both sound and electromagnetic waves. When the waves come into contact with these...
