Abstract (in Japanese) (See Japanese page) 
(in English) Many clinical results have been reported in the treatment of refractory fractures with LIPUS. However, the initial mechanism of the bone healing by ultrasound has not yet been elucidated. One possible mechanism is the piezoelectric phenomenon that occurs when high-frequency stresses such as ultrasound are applied to the bone. To quantitatively evaluate the piezoelectric properties of bone in the MHz range, our group has fabricated ultrasonic transducers (bone transducers) using bovine cortical bones and experimentally examined the induced potentials in bone by ultrasound irradiation. In this study, we report our experimental study on the distribution of ultrasound-induced potentials in a bone specimen and discuss the ultrasonic wave velocity and orientation of hydroxyapatite in bone.
