Abstract: The laser induced pressure pulse method has been used to study the non-uniform polarization distribution in 0.8 mm thick vinylidene fluoride/trifluoroethylene copolymer (P(VDF-TrFE)) films. Sprayed-on black paint was initially used as the target material and this led to the generation of a bipolar pressure pulse in the sample. With a different target material, we can now produce a monopolar pressure pulse. Measurements have been carried out using the new target material and the piezoelectric coefficient e[sub zz] has been estimated.
