NASA's Langley Research Center, in collaboration with Michigan State University (MSU), has developed a microphone array that...
Briefs: Test & Measurement
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,...
Briefs: Semiconductors & ICs
It is often desirable to sense the angular position of a rotating part. Numerous kinds of rotation sensors have been developed over the years; one type is a capacitive sensor, where a capacitance...

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...
Briefs: Nanotechnology
When hit with light, semiconductors (materials that have an electrical resistance in between that of metals and insulators) generate an electric current....
Briefs: Defense
Optical fibers have been traditionally produced by making a cylindrical object called a preform — essentially, a scaled-up model of the fiber — and then heating it. Softened material...

Algorithm Enables Drones to Work in a Coordinated Approach
An algorithm was developed that enables a team of unmanned aerial vehicles (UAVs) to communicate and work toward a common goal. The tool could be used to improve security or capture images simultaneously over a large area.
Briefs: Data Acquisition
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...
Briefs: Sensors/Data Acquisition
To further develop semiconductor technology, the field of molecular electronics is seeking to manufacture circuit components from individual molecules instead of silicon. Because of...

Faster Photons Could Make Data Totally Secure
Transferring data using light passed along fiber optic cables has become increasingly common over the past decades, but each pulse currently contains millions of photons. That means that in principle, a portion of these could be intercepted without detection. Secure data is already encrypted, but if an...
