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...

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...

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...

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 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...

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...

Researchers have developed a new propulsion concept for swimming robots that exploits temperature fluctuations in the water for propulsion without the need for an engine, propellant, or power supply.

Robots that are adapted to respond to physical human-robot interaction (pHRI) traditionally treat such interactions as disturbances, and resume their original behaviors when the...

When heated, popcorn can expand more than 10 times in size, change its viscosity by a factor of 10, and transition from regular to highly irregular granules with surprising force. These unique qualities can...

NASA's Langley Research Center, in collaboration with Michigan State University (MSU), has developed a microphone array that...

NASA's Marshall Space Flight Center is offering opportunities for its new fiber optic mass flow sensor system. Capable of measuring multi-phase flows in a pipe, the technology is minimally invasive,...

A process for engineering next-generation soft materials with embedded chemical networks that mimic the behavior of neural tissue lays the foundation for soft active matter with highly...

Wearable technologies are exploding in popularity in both the consumer and research spaces, but most of the electronic sensors that detect and transmit data from wearables are made of hard,...

A device and method have been developed to conduct compression and tensile tests on soft materials such as flocculated sediments, biopolymers, biological materials, and food stuffs. The device...

The measurement of mechanical behavior in very small samples whose dimensions are on the order of microns and below can offer advantages over conventional macroscopic testing in many instances. Motivations for investigating...

The Army uses robots that are structurally rigid, making them impractical when performing military operations in highly congested and contested urban environments where covert maneuvering is critical...

Researchers have developed an inkjet printing technique that can be used to print optical components such as waveguides. Because the printing approach can also fabricate...

The unique capabilities of soft robots are to bend, deform, stretch, twist, or squeeze in all the ways that conventional rigid robots cannot. Today, it is easy to envision a world in...

In the early years of manned flight, wing warping was used for lateral control of an aircraft. This technique consisted of a system of pulleys and cables used to twist the trailing edges of the wings in...
