Bismuth ferrite (BiFeO3) powders were synthesized by sol-gel methods and incorporated into flexible composites by hot pressing with polyvinylidene fluoride (α-PVDF). Several metal ions with various valances were used to dope BiFeO3 in order to examine their influence on electrical properties. XRD characterization confirmed that almost all of the dopants incorporated very well into the perovskite structure. Microstructural study showed that the composites are homogeneous with thickness of 50 to 140 μm. Dielectric, impedance and ferroelectric properties of composite samples showed that all of the dopants even those with smaller valence than the ions they substitute enhance the capability to handle the electric field. α-PVDF matrix also helped in preventing electrical breakdown comparing to BiFeO3 ceramics, which is usually susceptible to high leakage. Flexible composites were subjected to impact piezoelectric test with the idea to study their potential to collect mechanical energy from t...he surrounding vibrations.
