Correlation between low-frequency electric conductivity and permittivity in the diaphysis of bovine femoral bone

The relationship between the low-frequency electric properties in the axial, tangential, and radial directions along the diaphysis of a femoral bovine bone is presented. It is shown that below 1 MHz the relative permittivity of the diaphysis exhibits a significant positive correlation with respect to the low-frequency conductivity, as measured in any direction, and therefore it could be related to the amount of fluid contained in the channels that provide low-frequency electrical connectivity in the measurement direction. There is no significant correlation between permittivity, in either of the three measurement directions, and the total fluid volumetric fraction in the bone.
