Position-dependent characterization of bone tissue with electrical impedance spectroscopy

The 2012 IEEE Sensors Conference Proceedings
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.
