Piezoelectric Effects in Collagen

Open access
Fukada, Eiichi, Yasuda, Iwao·1964·Japanese Journal of Applied Physics

Abstract

The direct and converse piezoelectric effects have been observed in the Achilles tendon of ox and horse, which consists of collagen fibers in which the collagen molecules are highly orientated and crystallized. The matrix of piezoelectric constant is concordant with that derived for and unidirectionally oriented system of crystallites of collagen with a hexagonal symmetry. The magnitude of piezoelectric constant is: -d14=d25=8.0×10-8,d15=d24=4.2×10-8,d31=d32=0.26×10-8,d33=0.2×10-8 c.g.s.e.s.u. respectively, which are the largest values observed in the crystalline polymers. The origin of the effect is supposed due to the polarization or displacement of hydrogen bonds being formed in the polypeptide chains of collagen crystals. The gramophone pick-up can be made by using the thin sheet of tendon as an electromechanical transducer.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
