Abstract
While the threat of chemical and biological weapon deployment has increased alarmingly in recent years, the sensitive and specific detection of chemical warfare (CW) agents remains a significant challenge. To achieve maximum effectiveness, small inexpensive sensors are required for deployment in a user-wearable badge format. Satisfying these demanding requirements necessitates a novel approach to CW agent sensing. A particularly attractive approach is to exploit the powerful detection capabilities of conductive polymers, plastic materials whose electrical properties can be engineered to change in a sensitive and controlled manner upon exposure to specific chemical species. Chemical specificity is achieved by constructing an array of polymer sensors whose composite response provides a unique sical Sciences Inc. (PSI) proposes to develop a simple, inexpensive microsensor system for ultrasensitive, specific detection of CW agents. The system consists of a replaceable array of conductive polymer sensors coupled to a readout device. The microsensor will be credit card-sized, and ruggedized for battlefield deployment.In Phase I a prototype microsensor system will be constructed to demonstrate detection of agent simulants in the presence of battlefield interferents. The Phase I results will be utilized to complete a preliminary design of the Phase II system.
