Orthogonal Sensors for Trace Detection
R2-B1

Summary of technical approach

  • Our thermodynamic sensor works much the same way as a micro-calorimeter; except we measure the heat effect associated with the interaction of target molecules with a metal oxide catalyst.
  • Our conductometric sensor platform measures the change in electrical resistivity of the same metal oxide catalyst when explosive molecules adsorb on the surface of the catalyst.

Relevance to the Homeland Security Enterprise

The sensor is designed to detect trace explosives efficiently and accurately. The built-in redundancy of this sensor platform can reduce the frequency of false positives, a desirable attribute for any passive detection system.
