Estimating the true piezoelectric properties of BiFeO₃ from measurements on BiFeO₃-PVDF terpolymer composites

BiFeO₃ is an interesting multiferroic material with potential use in sensors and transducers. However, the high coercive field and low dielectric strength of this material make the poling process extremely difficult. Poling becomes a lot easier if the ceramic particles are incorporated in a non-conductive polymer with comparable...
