Rectangular bone samples prepared from the middiaphysis of the wall of animal bone are exposed by ultrasonic field having frequency of 2.5 MHz. The bone matrix changes under ultrasound exposure which results into the generation of potential in bone. The present study may be helpful in the development of acousto-elcctric devices.展开更多
