• Description:
  In this report, we summarize the work aimed at developing a prototype for a compact, person- wearable monitor for real-time detection of NO2. The prototype monitor developed by Platypus Technologies consists of a sensing element that exhibits an optical response when exposed to gas streams containing NO2, and an electronic system that reads the state of the sensing element and produces a visual alarm if NO2 is detected. The sensing element can detect the presence of NO2 at concentrations between 0.5 - 10 ppm in less than 1 minute. Moreover, we demonstrate that the LC sensor does not exhibit false-positive responses in the presence of non-target gases, and remains sensitive to NO2 even in the presence of non-target gases, or under a wide range of relative humidity levels (0 - 80% RH) and temperatures (0 - 35 degrees C). In addition, we built an electronic monitor to accommodate individual LC-based sensing elements, read the state of the sensing elements and alarm if NO2 has been detected. This prototype personal monitor was successfully tested in a laboratory and in a simulated lab environment, where its wearability and fast detection of NO2 were tested. Despite the tremendous technological developments achieved under this contract, further work is required to refine the current prototype and bring this technology to market.
