Abstract: Toxic Industrial Chemicals (TICs) are a great concern for the U.S. Department of Homeland Security (DHS) since they would be easier for terrorists to obtain and use than Chemical Warfare Agents (CWAs). Hence, a wearable low cost (less than $50) multi-gas sensor is needed to alert first responders to the type and level of hazard they face. Such wearable sensors will also find use in the much bigger industrial worker safety monitoring market. In this SBIR Project TDA Research, Inc. (TDA), with Texas Tech University (TTU), is developing a simple, low cost wearable smart sensor badge that has high sensitivity and selectivity to multiple TICs at trace (low parts per million) concentrations and triggers distinct alarms. The wearable smart badge is smaller than 2 in. x 2 in. x 0.5 in. and can detect multiple TICs of interest with a low rate of false alarms. We met all the proposed Phase I technical objectives, we demonstrated a fully integrated prototype chemical sensor badge that can detect and quantify H2S and ammonia, and obtained performance data that included results for these two TICs both separately and together in the presence of other contaminants such as CO, C6H6 and smoke. We also carried out a detailed design of the high fidelity sensor badge, generated 3-D models and assessed its techno-economic merits. In Phase II we will improve the sensor selectivity and fabricate at least six prototype wearable sensor badges to demonstrate their ability to detect at least 4 of the target TICs.
