4D Printing of Lead Zirconate Titanate Piezoelectric Composites Transducer Based on Direct Ink Writing
نویسندگان
چکیده
Lead zirconate titanate (PZT) piezoelectric composites used in transducers were fabricated via direct ink writing (DIW) combined with furnace sintering and resin impregnation. A ceramic slurry a volume fraction of 52 vol% suitable viscoelasticity was prepared. After post-process, the PZT specimens showed nanoscale grain size density 7.63 g/cm 3 , accounting for 97.8% theoretical density. The effects different printing rod spacing on electrical properties evaluated lucubrated. Finally, an underwater acoustic transducer assembled by using above method. signal generated changed autonomously stimulation, which indicated application mode 4D functional devices future.

In this paper we report an unprecedented level of integration of self-actuated nanoelectromechanical system (NEMS) resonators based on a 150 nm thick lead zirconate titanate (PZT) thin film at the wafer-scale. A top-down approach combining ultraviolet (UV) lithography with other standard planar processing technologies allows us to achieve high-throughput manufacturing. Multilayer stack cantilev...

This work reports on the development of a Lead Lanthanum Zirconate Titanate (PLZT) bulk ferroelectric poled ceramic structure as a Piezoelectric Plethysmograph (PZPG) sensor. The ceramic was implanted during its fabrication with a platinum (Pt) wire which works as an internal electrode. The ceramic was then submitted to an experimental setup in order to validate and determine the Pt-wire mechan...
متن کاملEffects of thickness on the piezoelectric and dielectric properties of lead zirconate titanate thin films
Lead zirconate titanate ~PZT! thin films with a Zr/Ti ratio of 52/48 were deposited on platinized silicon substrates by a sol-gel method and crystallized with preferred ~111! or ~100! orientation. Both the piezoelectric properties (d33) and the field-induced strains of the films with different thickness and preferred orientation were measured by a laser Doppler heterodyne interferometer. The we...
متن کاملResidual stress effects on piezoelectric response of sol-gel derived lead zirconate titanate thin films
Piezoelectric properties of three sol-gel derived Pb Zr0.53Ti0.47 O3 thin film specimens of different thicknesses integrated onto Pt/Ti/SiO2 Si substrates are investigated to delineate the influence of residual stress on the strain-field response characteristics from other thickness related effects. Residual tensile stresses are determined from wafer curvature measurements for films ranging in ...
