Unit cell electric arrangement of piezoelectric crystals may be described by various multipole/octupole/dipole electric moments which corresponds to a three/two/one-dimensional intrinsic polarity respectively. Such a latent polar structure is totally self-compensated in piezoelectrics if they are mechanically free, but it is non-compensated in pyroelectrics and ferroelectrics. Uniform but anisotropic partial clamping destroys a total self-compensation of non-central crystal intrinsic polarity. This decompensation allows to observe a polar response that is a "dipole projection" ΔP_{i} from, broken by clamping, spatial polar arrangement of piezoelectrics.
