Frequency characteristics of an electrode-separated piezoelectric crystal sensor in contact with a liquid

Abstract

The equations characterizing the frequency response of an electrode-separated piezoelectric crystal (ESPC) sensor, with one side in contact with a liquid, to the properties of the liquid were derived from an electric equivalent circuit model and supported by experiments. The frequency shift of the ESPC can provide information on the permittivity, conductivity, density and viscosity of the liquid.
