Abstract: A surface acoustic wave (SAW) impedance sensor was constructed by combining a 61 MHz SAWresonator with the conductive electrodes.Responses of such SAWimpedance sensor were investigated for different electrolyte solutions arid nonaqueous solutions.Afrequency shift-electrolytic conductivity equation was presented as △f=aX+b.The sensor was applied to the rapid determination of total salt content in serum and micro-water content in organic solvent.
Key words: Surface acoustic wave, Impedance sensor, Application in liquid phase
