In collaboration with the University of Tennessee, Y-12 has developed a new low-cost sensor technology, known as ChIMES (Chemical Identification by Magneto-Elastic Sensing), that uses target response material (TRMs) as actuators in magneto-elastic sensors. TRMs can come from many classes of chemical and biochemical compounds, with many degrees of selectivity. TRMs with strong affinities for specific targets can be used individually, while TRMs with distributed selectivity can be formed into arrays with an artificial neural network or other artificial-intelligence-based tools used for analysis and interpretation. The magneto-elastic components are amorphous ferromagnetic alloys with high permeability and very low coercively. When a TRM encounters a target, it imposes forces that change the magnetic properties of the alloy in ways that can be detected with an excitation-detection coil set.
Patent Abstract: 
The sensor can detect anything for which TRMs can be identified or developed. It is capable of untethered communication through a nonmetallic or thin metallic barrier. The sensor can be miniaturized and energy-efficient enough for power with on-board batteries.
Shape, size, and appearance can be tailored to a specific need -It is suitable for both overt and covert applications and can detect multiple and variable targets simultaneously with modular TRMs -The sensor is much less expensive than techniques like gas chromatography
