Nowadays mechanical energy is one of the most used sources due to the easy
way to generate it. This important characteristic has a great impact for energy
harvest and storage techniques. According to this, piezoelectric ceramics are
able to realize an optimum electrical/mechanical energy conversion through
electromechanical coupling. Until now, lead‑based ceramics
dominates the market of piezoelectric devices owning to their excellent
electrical properties, however, new environmental regulations restrict the use
of lead in electronic devices. Therefore, developing environmental friendly
electroceramics with enhanced piezo-ferroelectric characteristics is desirable. In
the past decade, with the objective of achieving a significant improvement in the
piezoelectric activity of BaTiO3-based ceramics have gained much attention. In
particular, Ba1-xCaxTi0.9Zr0.1O3 (BCTZ) properties are enhanced in the proximity
of a morphotropic phase boundary (MPB), due to a low energy barrier for
polarization rotation and lattice distortion. In this work BCTZ ceramics
