Abstract: Range of interlacing resistance of woven electrode is induced. Mathematical models of field point potential, electrode potential and electrode potentials difference are constructed. Electrode potential is the weighted mean of field point potentials at interlacing points. Effects of position, size of electrode, and contact resistance on electrode potential are investigated by simulation. Results indicate that there exists two extreme value points at which electrode potential reaches maximum and minimum, respectively. The absolute value of electrode potential extreme value decreases with the increase of electrode’s size. The electrode potential is independent of contact resistance if the expectation of contact resistance isn’t far greater than the interlacing resistance.
