Technology Marketing Summary

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. 

Description

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.

Benefits
  • 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
Applications and Industries
  • Explosives or taggants
  • Chemical and biological warfare agents, and precursors or by-products of CBRNe manufacture
  • Exhaled gas constituents for health diagnostics and drug detection
  • Toxic Industrial Chemicals (TICs) and Materials (TIMs)
  • Volatile organic compounds (VOCs) and other airborne and waterborne pollutants
  • Food freshness and safety

Wireless radiation sensor
Disclosed is a sensor for detecting radiation. The sensor includes a ferromagnetic metal and a radiation sensitive material coupled to the ferromagnetic metal. The radiation sensitive material is operable to change a tensile stress of the ferromagnetic metal upon exposure to radiation. The radiation is detected based on changes in the magnetic switching characteristics of the ferromagnetic metal caused by the changes in the tensile stress.

Wireless sensor for detecting explosive material
Disclosed is a sensor for detecting explosive devices. The sensor includes a ferromagnetic metal and a molecular recognition reagent coupled to the ferromagnetic metal. The molecular recognition reagent is operable to expand upon absorption of vapor from an explosive material such that the molecular recognition reagent changes a tensile stress upon the ferromagnetic metal. The explosive device is detected based on changes in the magnetic switching characteristics of the ferromagnetic metal caused by the tensile stress.

Wireless sensor
Disclosed is a sensor for detecting a target material. The sensor includes a ferromagnetic metal and a molecular recognition reagent coupled to the ferromagnetic metal. The molecular recognition reagent is operable to expand upon exposure to vapor or liquid from the target material such that the molecular recognition reagent changes a tensile stress upon the ferromagnetic metal. The target material is detected based on changes in the magnetic switching characteristics of the ferromagnetic metal caused by the changes in the tensile stress.
