11. Theoretical Study on the Piezoelectric Performance of Lead‐Free 1–3‐Type Composites.

Abstract

The paper is devoted to the analysis of high‐performance piezo‐composites based on lead‐free ferroelectric single crystals. The composite consists of parallelepiped‐shaped single‐crystal rods which are surrounded by a laminar polymer matrix, and the composite as a whole is described by 1–2–2 connectivity. Such a composite structure promotes high piezoelectric sensitivity and hydrostatic response. Of particular interest are piezoelectric coefficients g 33 * and h 33 *, squared figure of merit d 33 * g 33 *, electromechanical coupling factor k t * at the thickness‐mode oscillation, and hydrostatic parameters g h * and d h * g h *. The influence of the laminar matrix on the aforementioned parameters is studied in a wide volume‐fraction range. Examples of maxima and large anisotropy of some effective parameters are discussed for the 1–2–2 composites based on [Lix(K1−yNay)1−x](Nb1−zTaz)O3:Mn single crystals. The role of elastic properties of the laminar matrix in achieving large hydrostatic parameters and piezoelectric anisotropy of these composites is emphasised. Their effective parameters are compared to those of composites based on the lead‐containing relaxor‐ferroelectric single crystals and to specific parameters of poled textured ceramics. Advantages of the studied composites over the relaxor‐ferroelectric‐based composites and textured ceramics open up new possibilities to apply the 1–3‐type lead‐free composites as active elements of piezoelectric sensors, hydrophones, energy‐harvesting, and transducer devices.

12. Electromechanical Coupling in the Novel 2-2 Parallel-Connected PMN-0.33PT Single-Domain Crystal/Polymer Composite.

Abstract

This paper considers effective electromechanical properties of the relaxor-ferroelectric crystal/polymer composite with 2-2 connectivity. A single-domain 0.67Pb(Mg1/3Nb2/3)O3—0.33PbTiO3 crystal/polymer composite is proposed in which the polarisation vectors of components are tailored to optimise the electromechanical coupling factors k*3j and k*h. A strong correlation between the hydrostatic electromechanical coupling factor k*h and the hydrostatic piezoelectric coefficient d*h is observed near min k*h and max k*h. Examples of the condition k*31=k*32 are also considered. The specific advantages and potential of the 2-2 composite in terms of its considerable d*h and k*h values are discussed in connection with the studied orientation effect. [ABSTRACT FROM AUTHOR]
