Abstract

Fractional-order parametric models are popular in applications in material sciences, but they are not applied to biological systems. Recent research showed that they seem a good choice to model the human respiratory impedance. The purpose of this contribution is to implement such a fractional-order model for the human impedance, with electrical ladder networks of integer-order. The conclusion is that the number of rungs is an important design parameter to obtain a good approximation.
