An equivalent four-terminal model of an impedance tomography sensor in the measuring channel is presented. The frequency dependence of the potential difference measured between voltage electrodes of… (More)
It appears that a four-electrode conductance cell designed and used according to the van der Pauw method can be applied for the absolute determination of the electrolytic conductivity of solutions… (More)
Two types of multi-electrode sensors (with conducting and insulating walls), used in the impedance tomography systems, have been considered theoretically using finite element analysis (FEA). The… (More)
