Abstract

In this paper, a new configuration of the electrodes, called divided electrode, is proposed for a short time measurement of bio-impedance in a cross section of a local tissue. Its capability is examined by computer simulations, where a distributed equivalent circuit is used as a model of the tissue. Estimation of impedance parameters is carried out by use of the Gauss-Newton Method. As a result of them, usefulness of the proposed method is confirmed by computer simulations using a typical layered tissue model.
