Paper Abstract

In an unattended implanted or mobile ground sensor scenario, the microcantilever platform is well suited: sensor power consumption has been demonstrated at the nanowatt level and, as a microelectromechanical system, the platform is inherently compact. In addition, the remarkable sensitivity, low cost, scalability, and versatility of microcantilever sensors make this technology among the most promising solutions for unattended ground sensing of chemical and biological agents, as well as explosives. The University of Nevada, Reno, and Nevada Nanotech Systems, Inc (NNTS) are currently developing a microcantilever-based detection system that will measure trace concentrations of explosives, toxic chemicals, and biological agents in air. A baseline sensor unit that includes the sensor array, electronics, power supply and air handling has been designed and preliminary demonstrations of the microcantilever platform have been conducted. The envisioned device would measure about two cubic inches, run on a small watch battery and cost a few hundred dollars. This first design is tailored to shipping container monitoring, but is a broadly applicable device for passive or active monitoring scenarios.
