Abstract
The microstereolithography (μSL) of lead zirconate titanate (PZT) thick films on platinum-buffered silicon substrates is reported for the first time in this paper. Crack-free PZT thick films (80-130 μm thick) have been fabricated by laser direct-write UV polymerization from the HDDA-based UV curable PZT suspensions. The characterization of the fired films shows dielectric permittivities of 120-200, tangent loss of 0.92-2.5% and remnant polarization of 0.9-1.7 μC/cm2. The field-induced longitudinal piezoelectric coefficient (d33) of an 84-μm thick film is 100 pC/N and the piezoelectric voltage coefficient (g33) is about 59.5 × 10-3 V m/N. These results demonstrated the potential for μSL of advanced piezoelectric microsensors and microactuators.
