; (2) where P is the polarization; Pm is the maximum polarization; S is the strain; Sm is the maximum strain; εi is the initial permittivity; di is the initial piezoelectric constant... should be defined differently according to field direction (i.e., upward or downward). Another important point is the relationship between polarization and strain. The almost linear relationship appears......
