Embedded piezoresistive microcantilever (EPM) sensors may be constructed for a variety of sensing applications. In each application, a custom sensing material is designed that will respond volumetrically to the desired analyte. Here, we have constructed EPM sensors for the detection of chlorine gas (Cl2). The sensing materials used consisted of polymer matrices combined with sodium iodide crystals. Sensors constructed from a silicone-based matrix exhibited the greatest response to Cl2, with detection limits in an outdoor exposure setting of approximately 20 parts per million.
