Sponsored by the Office of Naval Research's (ONR) TechSolutions program, the Flashing Light to Text Converter (FLTC) features a camera that can be mounted atop a signal...

Briefs: Photonics/Optics

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...

Briefs: Propulsion

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.

Briefs: Photonics/Optics

The underwater environment may appear to the human eye as a dull-blue, featureless space. However, a vast landscape of polarization patterns appear when viewed through a camera that is...

Briefs: Transportation

Marine-grade stainless steel is valued for its performance under corrosive environments, and for its high ductility — the ability to bend without breaking under stress. But conventional...

Briefs: Materials

An eel-like robot was developed that can swim silently in salt water without an electric motor. Instead, the robot uses artificial muscles filled with water to propel itself. The...
