N2 - We have succeeded in enhancing the piezoelectric property of lead zirconate titanate (PZT) thin films by employing 'pulse poling' technique. We have fabricated MEMS-based microcantilevers using Pb(Zr0.52,Ti0.48)O3 (MPB-PZT) thin films. By applying 1 kHz and 100 V of unipolar triangle pulse voltage, the transverse piezoelectric constant -d31 of the PZT thin film has been enhanced as high as 105 pm/V, which is larger than the dc-poled PZT thin films (78 pm/V). The -d31 of pulse-poled the PZT thin films measured under the unipolar actuation at 0-12 V reaches 158 pm/V. The results indicate that only 1 second of pulse poling gives better piezoelectric property of the PZT thin films compared to several minutes of dc poling.
