Under the non-isotropic boundary conditions, piezoelectric quartz crystal discovers electrical response on scalar actions, the same as pyroelectric crystal. Thus, uniform change of temperature causes a secondary-type artificial pyroelectricity, while hydrodynamic change of pressure gives rise to a volumetric piezoelectric effect. Quartz voltage responsivity and figure of merit are of the same values of magnitude as in conventional pyroelectrics. Quartz type piezoelectric crystals, with their excellent mechanical, chemical, thermal and electrical properties, extend the number of pyroelectric materials and possibilities of their application.
