title = "Micromechanical models for the effective electromechanical properties of cellular piezoelectret polymer film",
abstract = "Cellular piezoelectret film is actually the voided charged polymer film. They show very large piezoelectric effect in the film thickness direction, and have great potential in the application of flexible electromechanical sensor. In this paper, cellular piezoelectret film is considered as a composite where the voids containing charges of opposite polarities are viewed as inclusions, while the polymer as matrix. We develop a micromechanical model to find the effective electromechanical moduli of cellular piezoelectret film. Sensitivity analysis is presented for effective electromechanical moduli with respect to void parameters. Furthermore, this micromechanical formulation is extended to include the viscoelastic deformation of polymer matrix. Temporal evolution of the effective properties, including elastic modulus and piezoelectric d33 coefficient in the film thickness, of cellular piezoelectret film can be obtained.",
