Effects of surface impedance on current density in a piezoelectric resonator for impedance distribution sensing [PDF]

open access: yesApplied Mathematics and Mechanics, 2021
AbstractWe study the relationship between the surface mechanical load represented by distributed acoustic impedance and the current density distribution in a shear mode piezoelectric plate acoustic wave resonator. A theoretical analysis based on the theory of piezoelectricity and trigonometric series is performed.
