This study investigates Love-type wave propagation in a layered structure consisting of a functionally graded piezoelectric material (FGPEM) stratum followed by a semi-infinite couple-stress substrate exhibiting microstructural properties. Dispersion relations are obtained for electrically open and short conditions. Possible particular cases are discussed. The dispersion relation is reduced to the classical Love wave equation to validate the results. The influence of microstructural parameters, electromechanical coupling factor, thickness, functional gradedness and material parameters of the FGPEM stratum on the phase velocity of the Love-type wave has been scrutinized and illustrated graphically for electrically open and short conditions. The findings have meaningful practical application in the enhancement of efficiency and performance of sensors and transducers.
