Abstract
The effective piezoelectric coefficients and related energy-harvesting figures of merit of 1–0–3 and 1–2–2 composites are studied. In these composites the main component is the lead-free [001]-poled domain-engineered [Lix(K1-yNay)1-x](Nb1-zTaz)O3: Mn single crystal, where x = 0.06, y = 0.1 – 0.3, z = 0.07 – 0.17, and the level of Mn doping is 0.25 mol. %. The matrix represents either a 0–3 corundum ceramic/polymer composite in the 1–0–3 structure or a 2–2 laminar polymer composite in the 1–2–2 structure. An influence of the aforementioned heterogeneous matrix on the piezoelectric coefficients d3j * and g3j *, figures of merit d3j *g3j * and F3j *σ, and their anisotropy in the studied 1–3-type composites at volume fractions of the single-crystal component 0 < m ≤ 0.3 is analysed by taking into account an elastic anisotropy of the matrix. Large figures of merit d33 *g33 * and F33 *σ are accounted for by an influence of the large piezoelectric coefficient g33 of the single-crystal component. The studied 1–3-type composites are characterised by large values of the longitudinal piezoelectric coefficient g33 *, figures of merit d33 *g33 * and F33 *σ, and by the large anisotropy of d3j * and F3j *σ, which are important for transducer, sensor and energy-harvesting applications.
