title: A Novel Real-time Carbon Dioxide Analyzer for Health and Environmental Applications.
abstract: To be able to detect carbon dioxide (CO2) with high accuracy and fast response time is critical for many health and environmental applications. We report on a pocket-sized CO2sensor for real-time analysis of end-tidal CO2,and environmental CO2. The sensor shows fast and reversible response to CO2over a wide concentration range, covering the needs of both environmental and health applications. It is also immune to the presence of various interfering gases in ambient or expired air. Furthermore, the sensor has been used for real-time breath analysis, and the results are in good agreement with those from a commercial CO2detector.
