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

Abstract

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. It was also found an absence of significant correlation between permitivity, in either of the three measurement directions, and the total fluid volumetric fraction in the bone.
