Paper Abstract

The ultimate problem for trace detection is sampling. More sensors are needed in more places to successfully tackle the sampling problem-especially for low vapor pressure explosives that are difficult to detect from a distance. To solve this problem, compact, inexpensive, and robust systems are needed that have not sacrificed sensitivity or selectivity to achieve their goals. In response, Nevada Nanotech Systems, Inc (NNTS) is developing microcantilever-based Self-Sensing Array™ (SSA) technology that will measure trace concentrations of explosives, toxic chemicals, and biological agent signatures in air. Ultimately, this technology could enable a device that would measure about two cubic inches, run on a small watch battery and cost a few hundred dollars. This paper compares the selectivity of SSA technology to other detection technologies using the metric of orthogonal channel capacity (OCC).
