- Currently available low-dimensional piezoelectric materials show a low piezoelectric coefficient d(33) of merely 100pm V-1 with Pb(Zr, Ti)O-3-based materials at the high end. Here, we report very large piezoelectricity in Ba(Ti0.80Zr0.20)O-3-0.5(Ba0.70Ca0.30)TiO3 (BTZ-0.5BCT) lead-free nanostructures sintered as thin films (d(33) = 140pm V-1) and nanofibers (d(33) = 180pm V-1). The influences of lateral size, geometry, and the clamping effect on the piezoelectric performance were investigated for both thin films and nanofibers. Combining a high piezoelectric coefficient with environmental benefits, the BTZ-0.5BCT nanostructures provide the superior functions sought for highly efficient piezoelectric devices and electromechanical systems.
