概要
- 論文の詳細を見る
Liquid viscosity measurement using shear horizontal (SH) wave propagation characteristics on a piezoelectric ceramic thin plate is described. The mode conversion loss associated with the compressional component U_3 is zero, because the SH wave on the piezoelectric ceramic substrate poled along the horizontal axis has only the horizontal component U_2, The IDT has a much larger electromechanical coupling factor for the S_0 mode SH wave than that of the SH surface acoustic wave (SAW). The metal-coated condition of the liquid-loaded surface is essential for detecting the liquid viscosity. There exists a linear relationship between the fractional phase velocity change of the S_0 mode and the square root of the liquid viscosity. The measured results on liquid viscosity using the S_0 mode SH wave devices, for some concentrations of glycerol-water solutions, are in good agreement with the theoretical prediction.
