Study on Liquid QCM Sensor Design and its Response Model

Abstract:

We use quartz crystal material from a physical point of constitutive equations derived in detail combined with the boundary conditions of the liquid Kanasawa QCM response model and Martin correction BVD equivalent circuit model; then apply transmission line theory and the theory of Acoustic impedance load, the research results can be useful as a QCM-D model, response model and Martin mode, then in-depth analysis of the liquid phase conditions, factors affecting the QCM frequency change, we propose a new method for measuring the density of the unknown liquid viscosity supplement. The main purpose of this chapter is to illustrate the viscous liquid medium under contact conditions, based on transmission line theory and the theory of load Acoustic impedance method compared to the classical method is simple, accurate, and effective.
