What's the difference between pyroelectric and pyroelectrical?
Pyroelectric
Definition:
(a.) Pertaining to, or dependent on, pyroelectricity; receiving electric polarity when heated.
(n.) A substance which becomes electrically polar when heated, exhibiting opposite charges of statical electricity at two separate parts, especially the two extremities.
