Effective transverse piezoelectric coefficient e31,f has been measured on (100)/(001) sol-gel Pb(ZrxTi1−x) thin films with compositions between 30% and 45% Zr. A maximum value of 8.07 ± 0.36 C/m2 at 40% Zr is found. The influence of the poling field ranging from 50kV/cm to 250 kV/cm has been evaluated.
