Abstract :
Palladium (Pd) nanowires were synthesized by electro chemical deposition technique. Pd nanowires were transferred onto a ZnO/36deg LiTaO3 surface acoustic wave (SAW) transducer with an approximate operating frequency of 100 MHz. This operational frequency approximately corresponds to the device´s highest conductometric sensitivity. These devices were investigated for hydrogen (H2) sensing at the room temperature. It was observed that the device exposure to the H2 gas resulted to a measurable increase in the device operating frequency
