Web10 jun. 2024 · One is passive electrodes and the other is active electrode technology. Passive electrodes are traditional EEG electrodes that simply transmit the voltage fluctuation to the amplifier through a conductive wire. To attain a low-impedance contact we use Silver-Silver Chloride (Ag/AgCl), or gold electrodes. However, the need for skin … Web16 jul. 2008 · Skin burns at the indifferent electrode have been identified and reported in electrosurgical procedures[2,4,5] where the procedure typically lasts longer and requires higher energies. The electrical current passing through the body produces heat energy and increases the temperature of the tissues. WebThe measured resistance increased asymptotically as the distance between the electrodes was increased. When the indifferent electrode diameter was at least 10 times the diameter of the spherical monopolar electrode, the measured resistance was within 5% of the value predicted for an indifferent electrode at infinity.
