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 CO₂ sensor for real-time analysis of end-tidal CO₂, and environmental CO₂. The sensor shows fast and reversible response to CO₂ over 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 CO₂ detector.
