Abstract

We propose a new configuration for SAW chemical sensing. A polymer coated SAW delay line device provides the coupling for synchronization of two stable self-sustained limit cycle oscillators. The dependence of synchronization frequency on the SAW delay time has been made the basis for chemical sensing. The analysis has carried out under conditions of weak phase coupling [1]. The dependence of synchronization modes on coupling parameters is analyzed. The sensitivity of a synchronization branch for vapor sorption induced delay perturbations is analyzed. This analysis shows the possibility of realizing high performance SAW sensors by this approach.
