Abstract
This work gives an overview of existing approaches to wireless strain and temperature measurements that employ passive sensors based on two types of SAW devices; reflective delay lines and one-port resonators. The performance of these two types of sensors is compared from the point of view of the achieved sensitivity, resolution, read range, interrogation time and power. A quantitative comparison of the wireless interrogation methods is presented.
