The piezoelectric activity of eight vinylidene fluoride-co-tetrafluoroethylene polymers was studied to further our understanding of this phenomenon. Film compliance, density, degree of crystallinity, and piezoelectric activity were measured in this study. It is shown that the piezoelectric d constant is calculable from a molecular dipole theory where the polarization is derived using a cavity reaction field. Author
