Transmission line equivalent model for lossy piezoelectric polymers and its SPICE implementation are presented. The model includes the mechanical/viscoelastic, dielectric/electrical and piezoelectric/electromechanical losses, in a novel way by using complex elastic, dielectric and piezoelectric constants - obtained from measured impedance of PVDF-TrFE sample. The equivalent circuit parameters are derived from analogies between lossy electrical transmission line and acoustic wave propagation. The simulated impedance and phase plots of polymer, working in thickness mode, have been compared with measured data.
