Effects of Stray Capacitance to Ground in Bipolar Material Impedance Measurements Based on Direct-Contact Electrodes

Bipolar material impedance measurements are easier to implement than tetrapolar measurements but are more affected by electrode impedance. This effect can be reduced by measuring at a high-enough frequency albeit with the risk of deviations due to stray capacitances. High frequency measurements inte...
