Piezoelectric Effect in Bone [PDF]
Nature, 1963 THERE is convincing evidence that bone has an orderly morphological and microscopic structure. This evidence is derived mainly from electron microscopy, ordinary histological preparations, and microradiography1. Such a structure, consisting essentially of apatite crystals embedded in an organic matrix, might be expected to exhibit piezoelectric ...
