摘要
Experimental results are presented for a surface-acoustic-wave gas sensor. At 150 degree C a pronounced selectivity towards NO//2 was observed. The transduction of a chemical signal concentration into a physical signal (SAW phase velocity) is discussed in terms of the effect of mass and conductivity changes on sensor response.
