Integrated Deployable Microsensors for Chemical Detection

Objective: Develop low size, weight, power, and cost (SWaP-C) microsensor for chemical threats that can be easily distributed and networked to support integrated early warning. Description: Design and fabricate a low SWaP-C microsensor that can be easily distributed across the battlespace would provide integrated early warning of chemical threats. A chemical threat microsensor will be designed to detect chemical weapons agents (nerve and blister classes) and pharmaceutical based agents in vapor and aerosol forms, in near real time. The sensor will maximize use of innovative sensing modalities to provide class-based, presumptive chemical threat detection in less than 10 minutes. The sensor will be readily deployable through multiple means, including unmanned vehicles, projectiles, or hand emplacement to enhance rapid response and decision making. The sensor will collect and feed high density data in near real time to support mission command systems and create a CBRN common operating picture. The sensor will self-calibrate and continuously operate in a complex operational environment. The final system will employ rapid and networked signal processing algorithms to exchange data with network operators. The final system should have a total mass less than 250 grams and a diameter no greater than 5 centimeters for the complete system, including power source (if applicable), and shall operate 24 hours or longer on a single charge with intermittent detections.
