It is predicted theoretically that a secondary pyroelectric effect will be observed in polar-neutral directions in noncentral crystals with an anisotropic limitation on thermal deformation. This prediction has been verified experimentally. This effect occurs in piezoelectric resonators in the frequency interval between the first and last acoustic resonances.
