Abstract

A shear horizontal surface acoustic wave (SH-SAW) sensor coated with polyaniline (PANI) was investigated in this study. The SH-SAW phase and attenuation were measured using a network analyzer. The sensor presented a sensitivity of 0.23 deg/ppm at 25°C. The minimum detection level was estimated to be 0.07 ppm at 25°C. Otherwise, the response of the SH-SAW sensor immediately followed the ammonia gas concentration. Hence, the SH-SAW coated with PANI exhibited an excellent response for detecting ammonia at room temperature.
