Presented here are the results concerning a hydrogen sensor based on a novel bilayer structure in a Surface Acoustic Wave dual-delay line and electric systems. The sensor material consists of two layers produced in two different vapour deposition processes. The first one is a metal-free pthalocyanine (H2Pc) layer, whereas the second is a ~20 nm thin palladium (Pd) film. This structure was simultaneously formed in a one of the SAW dual delay lines and on the interdigital electrodes of the glass substrate for electric measurements. In such a bilayer structure detection of hydrogen in a medium concentration range (from 1% to 4 % in nitrogen) is possible, even at room temperature. Preliminary measurements of this two bilayer structures has been performed simultaneously in the same chamber for this same measurements conditions. A good correlation of results between these structures has been observed.
