Kryshtal R. G., Kundin A. P., Medved A. V., et al. Liquids recognition by means of a sensor on surface acoustic waves of shear-horizontal polarization
Basic possibility of recognition of liquids by means of the single sensor on surface acoustic waves with shear-horizontal polarization is shown experimentally. No multi element sensor arrays were used in our work in contrast with the convenient recognition methods used in electronics nose or electronics mouth systems. Pulse characteristics measured at actions of some liquids are presented thus showing working capacity of the proposed sensor. Some experimental data demonstrating high enough reproducibility of measurement results is given. Some possibilities of application of molecularly imprinted polymers as selective layers in our sensors are discussed.
Keywords: liquids sensor, surface acoustic waves with shear-horizontal polarization, piezoelectric, sensors array, molecularly imprinted polymer, selectivity, morpholin, inverse fast Fourier transform, S-parameters.
