Classification: CPC H  B | IPC B  H

Claim 9:
10. An apparatus for generating electrical potential or current or both through a pyroelectric process comprising:
a cohesive mass of polycrystalline zinc oxide crystals having a lozenge or tablet shape with dimensions of at least 1.0 inch×1.0 inch×0.18 inch and electrically conductive elements embedded or affixed on or into opposing regions, surfaces, or facets of the shaped mass, the electrically conductive elements connected to an electrical circuit, the polycrystalline zinc oxide crystals being positioned in the cohesive mass to remain in intimate physical contact and to remain electrically communicative with each other;
a heating element arranged to heat said cohesive mass of polycrystalline zinc oxide crystals for a first period of time; and
a cooling element arranged to cool said cohesive mass for a second period of time to generate an electrical potential or current or both through the pyroelectric process.
