Frequency Dependence of Electrical Properties of Human Bone

Abstract

The use of electrical stimulation for treating non-unions and congenital pseudarthrosls has been reported, although the mechanism of the osteogenesis is still unknown. An analysis of the current and the current-path In bone night further the study of the mechanism of electrical osteogenesis. Such an analysis would be faclllltated by knowledge of the electrical properties of bone and their variation with frequency. In this study, resistivity, dielectric constant, dissipation factor, impedance and phase-angle have been measured for compact human bone at 0.5-108 MHz. the resistivity, dielectric constant, and impedance decreased with increasing frequency.
