Abstract
Love wave device is one of the typical SAW(surface acoustic wave) devices. Relative to other acoustic sensors, the Love wave liquid sensor has some obvious advantages. In this paper, the theory model of Love wave is established, the influences of liquid viscosity on propagation velocity and attenuation of Love wave are numerically analyzed. The changes of Love wave sensitivity to liquid viscosity and density with the ratio of the film thickness to the acoustic wavelength are numerically analyzed.
