Abstract
A method for fabricating a sensor system includes providing a surface acoustic wave (SAW) tag on a substrate including a detector bank of reflectors at one end to generate a detector SAW responsive to an interrogation signal, a reference bank of reflectors at an opposite end of the substrate to generate a reference SAW responsive to the interrogation signal, and a transducer between the detector and reference banks of reflectors for receiving the interrogation signal and transmitting the detector and reference SAW from the detector and the reference banks of reflectors in response. A hydrogen gas sensor is formed on the substrate in a propagation delay path (delay path) between the detector bank of reflectors and the transducer to modulate propagation parameters of the detector SAW in response to sensing hydrogen gas. The forming includes depositing a SnOfilm then depositing a Pd film onto the SnOfilm.
