“…These composite materials combine the best properties of the FE ceramics (high piezoelectric coefficients, low dielectric and mechanical losses, good thermal properties, large range of dielectric constant) with the advantages of the polymers properties (low density, high resistivity, excellent mechanical properties, formability and low cost) [9][10][11]. The micro-geometry of the FE ceramics inclusions and the interface between the filler and the matrix play an important role in the macroscopic electrical and mechanical properties of the composites due, among other factors, to the connectivity of the individual phases [12,13].…”
