Researchers at NASA’s Johnson Space Center (JSC) have patented an instrument for detecting ice and other superstrates on or near a sensor, for example a layer of ice on a road, bridge, or airplane wing. The technology can identify the presence or absence of a superstrate, as well as its type. Unlike other methods, this innovation can be built to conform to the profile of the surface it is monitoring (such as an airplane wing) so that it will not affect the aerodynamic profile. The instrument is composed of a microstrip transmission line, a mounted substrate, multiple measurement cells within the transmission line, and a microwave transmitter/receiver for interrogating the sensor cells. The innovation can operate wirelessly and be miniaturized to the size of a quarter. JSC has received patent number 6,995,572 for this technology.
Johnson Space Center has received patent protection (U.S. 6,985,606→) for this technology.
This technology is being made available through JSC’s Technology Transfer and Commercialization Office, which seeks to transfer technology into and out of NASA to benefit the space program and U.S. industry. NASA invites companies to consider licensing this technology for commercial applications.
