An Enhanced Quarter-Sized Optical NEMS Based Methyl Salicylate Sensor System (MS3)

Building on our successful Phase I work our Phase II objectives are to complete development and integration of our two proposed sensors into an unprecedented self-confirming MeS detection system further refining our ability to meet key requirements identified in Phase I. More specifically, we will develop a NEMS based MeS sensor system complete with a telemetry system and/or a remote logging, data collection, and analysis system. We will also construct and validate a referee system for testing and calibration of the system. Test results will be analyzed and sensor sensitivity plotted relative to the referee system. Based on test results, the sensor system will be optimized for performance. The system will be verified during multiple trials in a Man-In-Simulant Test chamber and the overall suitability of the equipment and test protocol will be evaluated. This detector will have the ability to operate at ambient pressure, function accurately in a rapidly fluctuating high humidity environment, and operate from 0 to 40 degrees Celsius. It will be placeable in a number of strategic body regions to track leak patterns, and not inhibit free movement of the test subject beneath the garment. The sensor system will support several hours of continuous operation.
