N2 - One-dimensional (1D) piezoelectric materials have been used in many electronic applications due to their high aspect ratio (length/diameter ratio). The modified polysulfone spinning method was used to prepare 0.02Sm-doped 0.47Pb(Mg1/3Nb2/3)O3-0.18PbZrO3-0.35PbTiO3 (abbreviated as Sm-PMN-PZT) ceramic fibres. The grain size and diameter of the Sm-PMN-PZT ceramic fibres were ∼4.5 μm and ∼500 μm, respectively. The piezoelectric coefficient (d33), relative dielectric permittivity (ε33/ε0), and coupling Factor k33 were found to be ∼780 pC/N, ∼6820, and ∼0.71, respectively. Based on the polarization versus electric field and dielectric permittivity versus temperature curves, the spontaneous polarization, coercive field, and Curie temperature were found to be ∼28.33 μC/cm2, ∼7.27 kV/cm, and ∼160 °C, respectively. These results indicated that Sm-PMN-PT ceramic fibres could be used in advanced electromechanical devices where high-performance 1D piezoelectric materials are needed.
