Abstract

The bio-impedance measurement method via electromagnetic induction has the non-contact character which overcomes influences of the electrode´s contact impedance to measurements. However its measurement results have a highly complicated relationship with impedance properties of measured objects. In order to discover the regularity, this paper deduces an analytical resolution model using a probe-coil and analyzes affections of conductivity and lift-off to mutual inductance variation. The achieved disciplinary characters are valuable not only to this measurement method using the probe-coil but also to the data analysis in Electromagnetic Tomography (EMT).
