摘要
Embedded piezoresistive microcantilever (EPM) sensors may be constructed for various sensing applications. In each application, a custom sensing material that responds volumetrically to the desired analyte is designed. Here, we constructed EPM sensors for chlorine gas (Cl-2) detection. The sensing materials used consisted of polymer matrices combined with NaI crystals. Sensors constructed from a silicone-based matrix exhibited the strongest response to Cl-2, with detection limits in an outdoor exposure setting of approximately 20 ppm.
