On the piezoelectric effect of bone
Web1 de out. de 2024 · Piezoelectricity also occurs naturally within the human body; bone, muscles and tendons present piezoelectric properties [[4], [5], [6], [7]].In bone, this behaviour has been attributed to semi-conductor characteristics [8, 9], and to classic piezoelectric effects [5].In addition, stress-generated electrical phenomena have been … WebThe piezoelectric effect was measured in samples of human bone and repeated with the same samples after either demineralization or decollagenation. The results indicate that at least part and possibly all of the piezoelectric effect found in whole bone arises from the organic component. The existence of two alternatives results from the unknown role of …
