(TU Delft Novel Aerospace Materials; TNO) Department Support Aerospace Engineering Date 2016-09-01 Abstract Modern flexible and sensitive sensors based on polymer–ceramic composites employ lead zirconate titanate (PZT) granulates having the morphotropic phase boundary (MPB) composition as the piezo active ingredient, as this composition gives the best properties in fully ceramic piezoelectric sensors. In this study, the possibility of using PZT granulates with compositions, which are not in the MPB region of the PZT phase diagram was investigated. Random 0–3 PZT–epoxy composites were prepared for the complete composition range of PZT ceramics [Pb(ZrxTi(1−x))0.99Nb0.01O3] with x ranging from x = 0 to x = 0.80. Piezoelectric and dielectric properties of such composites were systematically studied. It is shown that the highest voltage sensitivity (i.e. g33) of the piezoelectric composites is obtained for composition with much lower Zr levels (x To reference this document use: http://resolver.tudelft.nl/uuid:b45fd854-94ee-40e1-b6c5-e3a21269b5e6 DOI https://doi.org/10.1007/s10854-016-5029-9 ISSN 0957-4522 Source Journal of Materials Science: Materials in Electronics, 27 (9), 9683-9689 Part of collection Institutional Repository Document type journal article Rights © 2016 A.
