This paper presents results on measurements of surface
acoustic wave (SAW) sensor, using polymer liquid crystal layer. The
sensitivity and response time for different test probes have been studied.
The sensitivity of the order of 4 Hz/ppm or higher, towards such compounds as
N,N-dimethylacetamide (DMA), dimethyl methylphosphonate and dibutyl
sulphide, was found. The results show that the very high sensitivity towards
DMA results from interaction of DMA with structurally ordered liquid
crystalline material
