R&D Magazine – Duke University engineers have developed a novel sensor that is more efficient, versatile, and cheaper for potential use in such applications as airport security scanners and collision avoidance systems for aircraft, cars, or maritime vessels.
The material itself is a thin laminate with row-upon-row of tiny squares etched onto copper, each one of which is tuned to a different frequency of light. The material is flexible and durable enough to be attached to a wall, wrapped around corners or even laid on the floor like a rug, making it an inexpensive alternative for a variety of sensing applications. more> http://tinyurl.com/azlvdrj
