Microsensor for the Detection of Hypergolic Chemicals

GINER, Inc. proposes to design, develop and demonstrate a screen printed, thick-film electrochemical Monomethyl Hydrazine (MMH) and Nitrogen Dioxide (NO2) microsensor module (multi sensor cell with integrated potentiostatic control, signal processing, wired and optional wireless, data transmission circuit) that combines real time, rapid and simultaneous detection of 0 to 200 ppm of MMH and NO2 in one sensor substrate complete with its own battery power source. The microsensor will have a small footprint, low (less than 1.0 mA) power consumption and low cost (less than $200 for quantities larger than 5000 units), and will have a rapid response to MMH and NO2 changes inside a missile canister. The microsensor module will operate in a continuous (optional ON/OFF) mode displaying and sounding an alarm when either the rate of target chemical concentration change exceeds a pre-set value indicating a significant leak, or when the concentration of the target chemical exceeds a pre-set high threshold value regardless of the rate of change. Successful completion of the Phase I program will demonstrate feasibility of the proposed microsensor module for accurately and reliably detecting 0 to 200 ppm of MMH and NO2 and display alarms.
