“…To confer the repercussion of characteristic length parameter (l) of the micropolar media on the phase velocity of the Love-type wave propagation, values of l are varied as 0.000 01 m, 0.000 03 m, and 0.000 05 m. Here, micropolar constant is fixed as N=0. 7 The thickness of the both the layers are fixed as h l = 0.3 m and h p = 0.3 m, respectively. To capture the size effects on the phase velocity profile of Love-type wave in the piezoelectric layered structure the impact of characteristic length parameter is depicted by figures 3(a) and (b) for electrically open and short conditions, respectively.…”

The electromechanical coupling factor (K 2) is a key parameter in acoustic devices that acquaints the affect of piezoelectricity on the phase velocity of elastic waves. For conventional engineering applications, greater electromechanical coupling factor (K 2) are expected in surface acoustic wave (SAW) devices. This present study investigates the impact of microstructures and viscous liquid loading on transference of Love-type surface wave in a prestressed piezoelectric smart material layered structure. A micropolar material as substrate is employed for capturing the microstructural influence. The study involves the extraction of dispersion equations for both electrically open and short conditions depicting explicitly the effects of viscosity and density of viscous liquid, microstructural parameters of the substrate, electromechanical coupling factor and material parameters of the prestressed piezoelectric layer. Some particular cases of the problem are derived and the obtained results are matched with the classical Love wave equation. PZT − 5H ceramic material as piezoelectric material and Aluminium-Epoxy as micropolar material, are considered for the investigation. The present study is meaningful in intensifying the performance of chemical and biochemical sensors working in a liquid environment.
