Abstract
Measurements of the capacitance and conductance of bovine cortical bone have been performed at body temperature as functions of frequency, time, and humidity. A direct‐coupled low‐frequency bridge containing active circuits was used to study the response below 50 Hz. Results are expressed in terms of permittivity, dielectric loss tangent, and both frequency‐ and time‐dependent electric moduli. The permittivity was found to be extremely sensitive to frequency and humidity; maximum permittivity observed exceeded 105, while the maximum loss tangent was greater than unity. Anisotropy was observed; both the permittivity and the loss tangent were greater if the electric field was parallel to the bone axis.This publication has 9 references indexed in Scilit:
