THE PROPERTIES OF ELECTRODE CONDUCTIVITY MEASUREMENT METHODS OF BIOLOGICAL TISSUES

Popis výsledku v původním jazyce

This article analyzes properties of electrode conductivity measurement methods of biological tissues, which are one of the few able to measure the potentials of corresponding components of complex conductivity, thus real resistive component and an imaginary component reactive conductivity. The analysis was performed by computer modelling and experimental measurements. The publication describes modelling current and potential electrode methods for tissue phantoms using finite element method. Comsol Multiphysics v.3.4 program was used for calculations. Results are presented for 2D and 3D graphs. An experimental measurement with electrodes in the phantoms tissue with different conductivity was also conducted, and components of the complex conductivity were evaluated with RLC Bridge and most accurately by using the lock-in amplifier. The measured values of conductivity of the phantoms were used as reference values in the research of contactless methods of measuring conductivity.
