Definition

A centrosymmetric material has points of inversion symmetry throughout its volume. A material that does not is said to be non-centrosymmetric. This is a key requirement for piezoelectric materials: they must be non-centrosymmetric. Not all non-centrosymmetric materials are piezoelectric, however (the exception is materials with class 432).
