Popis:	Straight lead zirconate titanate (PZT) fibers with round cross sections were fabricated by extrusion with boric acid and polyvinyl alcohol (PVA) condensation. The sintered fibers showed more tetragonality than the bulk. The dielectric constant of the electrode area perpendicular to the PZT fibers (Z1) was higher than the electrode area parallel to the PZT fibers (R1). Single PZT fiber exhibited higher remanent/saturation polarization and coercive field than the bulk and composite. The piezoelectric constant d33 of the Z1 composite was 300 pC/N for the 75 vol% PZT fibers. The Z1 composite had flexibility and high dielectric and ferroelectric properties, and exhibited promise in conformable and large-area applications.
