Ferroelectric and piezoelectric materials have attracted a great deal of attention from scientific and technological points of view. In this paper, it is described that intergranular elastic strain accommodation in addition to lattice defects and domain walls plays an important role in the piezoelectric properties of PZT [ Pb(Zr, Ti)O3] ceramics. In addition, recent progresses and problems for Bi-based piezoelectric ceramics are briefly mentioned.
