Journal of the European Ceramic Society, Volume 35, Issue 13, November 2015, pp. 3475-34830955-2219https://doi.org/10.1016/j.jeurceramsoc.2015.05.013http://dspace.lib.cranfield.ac.uk/handle/1826/10207This paper reports the use of a printing technique, called electrohydrodynamic jet printing, for producing PZT thick film micro-scale structures without additional material removing processes. The PZT powder was ball-milled and the effect of milling time on the particle size was examined. This ball-milling process can significantly reduce the PZT particle size and help to prepare stable composite slurry suitable for the E-Jet printing. The PZT micro-scale structures with different features were produced. The PZT lines with different widths and separations were fabricated through the control of the E-Jet printing parameters. The widths of the PZT lines were varied from 80 μm to 200 μm and the separations were changed from 5 μm to 200 μm. In addition, PZT walled structures were obtained by multi-layer E-Jet printing. The E-Jet printed PZT thick films exhibited a relative permittivity (ɛr) of ∼233 and a piezoelectric constant (d33, f) of ∼66 pC N−1.enAttribution-Non-Commercial-No Derivatives 3.0 Unported (CC BY-NC-ND 3.0).
