Abstract :
SAW device is widely used in the various passive sensing application such as temperature, mechanical force and other various measurements. The SAW devices have relatively high the temperature dependency, thus in some applications, the multiple SAW sensors are used for the temperature compensation. In such a case, the communication between the sensor and controller is highly important. This paper describes the one channel communication with multiple SAW resonators for the measurement applications. The final target of this research is to investigate the near magnetic field wireless passive sensing capability using the continuous wave for higher response speed.
