National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Pyroelectric Effect in Bone and Tendon.

PB173792

Publication Date	1966
Personal Author	Lang, S. B.
Page Count	2
Abstract	The pyroelectric coefficient of the bone treated with nitric acid (the coefficient is based on the area of the sample before acid treatment) is about the same size as those of the untreated specimens. This indicates that the pyroelectric effect is caused by the crystallographic structure of the collagen molecule. Piezoelectricity and pyroelectricity are closely interrelated and so it would be reasonable to assume that the electric potentials in mechanically stressed bones are of a piezoelectric origin. The very small size of the pyroelectric effect in collagen containing materials probably precludes any physiological significance of the effect. There may be other biological materials in which the pyroelectric effect is of such magnitude as to be physiologically important.
