Bone is piezoelectric in nature and therefore capable of transforming mechanical stress into an electric charge. These moving charged particles produce a magnetic field. A magnetic sensor may be able to detect this field and thus may provide a measure of the stress wave amplitude in the bone. Such a sensor can potentially measure the properties of bone in-vivo.
