Electrical impedance spectroscopy is a non-invasive technology for characterizing the dielectric properties of biological tissues and cells. Electrical impedance tomography extends impedance measurements from one dimension to two or three dimensions. Impedance measurements are performed across multiple electrodes, mapping the conductivity distribution within an object. In this paper, electrical impedance...
In this paper the technique of nonlinear dielectric spectroscopy is employed to examine the nonlinear response of a suspension of the yeast S. cerevisiae to a low frequency perturbating ac electric field. Metabolically active and resting yeast states, as well as the electrolyte medium are considered, and experimental time-course spectral data are presented. Conductivity is found to increase in the...
