NASA Langley Research Center in Hampton, VA solicits inquiries from companies interested in obtaining license rights to commercialize, manufacture and market the following technology. License rights may be issued on an exclusive or nonexclusive basis and may include specific fields of use. NASA provides no funding in conjunction with these potential licenses. THE TECHNOLOGY: Scientists at NASA Langley Research Center have developed a wireless, open- circuit SansEC [Sans (without) Electrical Connections] sensor that can detect the presence of chemicals without being in contact with the chemical it is detecting. This unique thin-film sensor is used in conjunction with a chemical reactant that detects the presence of the chemical. Because of the way the sensor operates, the reactant can be separated from the sensor itself and placed in caustic or harsh environments, and can still work to detect the specific chemical it was designed to discern. The ingenuity of the thin-film design with the elimination of all wires, connections, and electronic components enables the sensors to be produced cost-effectively. This is an application of the NASA award-winning SansEC sensor, which is damage resilient and environmentally friendly to manufacture and use. The sensors use a NASA award-winning magnetic field response recorder to provide power to the sensors and to acquire physical property measurements from them. The SansEC sensor is an open circuit without electrical connections, which functions as an electrical simple harmonic oscillator when exposed to a harmonic magnetic field. Its response is dependent upon the measured physical property. It consists of a uniquely designed thin-film electrically conductive geometric pattern that stores energy in both electric and magnetic fields. When wirelessly interrogated using the NASA-developed Magnetic Field Response Recorder (U.S. Patent Number 7,159,774), the sensor becomes electrically active, and a chemical reactant works in tandem with the thin-film trace. If the chemical is present, it causes a change to the reactant, resulting in an alteration to the sensors magnetic field response attributes. The Magnetic Field Response Recorder notes this change electronically. U.S. patent 8,673,649.
