Electrical Properties of Wet Collagen

Abstract

THE electrical properties of dried collagen and bone have been studied by Fukada and Yasuda1,2. Both were shown to be piezoelectric, producing a measurable potential between opposite faces when stressed and also deforming on application of a voltage. The piezoelectric coefficients d14 belonging to the polycrystalline point group ∞ were found for collagen, and the values reported for d14 were about the same as d11 in quartz. Because both tendon and bone are bathed in ionic fluid of high conductivity when in vivo, it was decided that the electrical activity of wet collagen should be examined.
