SURFACE ACOUSTIC WAVE SENSOR SYSTEM FOR USING OSCILLATION METHOD AND SENSING METHOD USING THE SAME

摘要

Provided is a surface acoustic wave sensor system, in which multiplexers are connected to input and output terminals of a plurality of surface acoustic wave devices through one feedback loop, and thus one oscillation channel is configured. Such a surface acoustic wave sensor system can prevent errors caused by deviations between oscillators, and thus sensitivity and reproducibility can be improved.
