摘要：

The numerical method of calculation of characteristics of lateral electric field excited resonator contacting with viscous and conducting liquid and results of these calculations are described. The method based on finite element analysis allows to find the distribution of mechanical and electrical fields in piezoelectric plate and liquid and to calculate the frequency dependencies of electrical impedance and admittance of resonator. It has been shown that values of real parts of impedance and admittance on resonant frequencies unambiguously correspond to viscosity and conductivity of liquid. (C) 2015 The Authors.
