Due to their small size and ruggedness, SAW sensors have been widely used as part of wireless sensing system especially in inaccessible and inhospitable environments. SAW sensors find applications as physical, chemical and bio- sensors and also as ID tags. The passive wireless SAW sensing system mainly consists of a passive SAW sensor and an interrogation unit which sends a burst signal to the SAW sensor and processes the sensor response.
The main objectives of this work were to design and fabricate the interrogation unit which is a burst transceiver and also to design, model, simulate and fabricate SAW devices. Significant results obtained from the burst transceiver and simulation as well as fabrication results of SAW devices will be presented together with some of the challenges faced.
