Position-dependent characterization of bone tissue with electrical impedance spectroscopy

In the present contribution femur (leg bone) tissue excised from calves was investigated in vitro by electrical impedance spectroscopy in a frequency range of 40Hz-40MHz. Three different equivalent electrical circuits were tested for suitable representation of the measured data, where the fitting was performed by a complex nonlinear least-square algorithm. Finally, a depth profile of a bone sample is discussed.
