Personal Multi Analyte Sensor Badge for Toxic Industrial Chemicals

Sensera, Inc. proposes to develop a passive TIC multi analyte sensor badge. The badge is based on a detailed investigation of the properties of the analyte vapors and can be made in several configurations to suit the intended analytes. It can also be madeto have dual transduction capability. The badge will give a rapid general alarm with provision for further on site characterization of the threat.During Phase I, we will develop a promising library of reagents suitable for different sensor badge configurations. We will also conduct preliminary studies on various transduction modes. For the Phase I option, we will study in detail the use of liquidcrystals for visual indication and the design of the circuit for electronic monitoring. During Phase II, the design of the sensor badges will be optimized and actual units will be fabricated and tested. The proposed TIC detection badge has commercialapplications in both the industrial and civilian sectors. They include: hazardous material emergency response units, environmental pollution monitoring and cleanup, firefighter applications, hazardous gas detection in commercial and residentialapplications, and industrial monitoring of chemical plant operations.
