Received January 28, 1999; after revision April 15, 1999

The sensor proposed comprises an acousto-electronic element on surface acoustic waves with layers of materials sensitive to the specified chemical element applied onto the operating surface between complementary Golay-coded transducers. The sensor selectivity is governed by the combination of material properties and structure.
