Dielectric phenomenon of living matter

The frequency and time dependant activities of charge carriers in living tissue under electrical fields are found to be very sensitive to recently described domain structures in cells. An electromechanical model with an inertial element, equivalent to inductance in electrical circuits, is utilised to describe the cooperative correlation between domains, in contrast to the “free” dipole relaxation mechanisms in most polymer systems. The polarization current, due to voltage stimulation of cells, reveals a basic property that a field within living cells excites an elastic deformation with a relaxation nature. These mechanical shifts of domain boundaries in plant cells oppose to polarization processes in selected frequency ranges. The presence of intrinsic ions through damaged membranes overshadows this inertial effect. Using newly developed current measurements on animal tissue under elevated voltages, membrane elasticity and cell transformations, caused by chemical treatment, temperature changes and “freezing” were studied. The analysis of these perturbations during disease induction is a new and favoured topic of biomedical study
