| Outline of Final Research Achievements |
Shear horizontal (SH) acoustic wave sensors are suitable for liquid measurements, because the SH wave propagates at the liquid interface with small energy leakage. This sensor can detect the conductivity and viscosity. c-Axis parallel oriented ZnO film is a good candidate for the SH-wave excitation. Because these measurements were possible from SH-wave velocity changes, a highly sensitive sensor is expected if the long propagation path can be achieved with the multiple wave roundtrip system. In this study, a SH acoustic wave sensor consisting of c-axis parallel oriented ZnO film/silica glass planar substrate was fabricated. Then, viscosity and conductivity measurements were demonstrated. Next, a c-axis parallel oriented ZnO film/silica glass pipe structure sensor was fabricated, and the propagation characteristics of the multiple roundtrips were observed. New measurement systems of the liquid properties are expected with the multiple shear wave roundtrips.
