Abstract: The current distribution at plane electrodes of finite breadth is calculated under the assumption of a linear polarization curve. The current distribution at triangular‐wave profile electrodes is calculated for zero polarization, and an approximate solution is given for high polarization. Results of the theoretical analysis are compared to experimental data reported by Mantzell. It is shown how measurements with the Haring cell can be used to predict current density distributions for other geometrical conditio… Show more

“…While results in animals generally show that threshold charge decreases with electrode diameter, the threshold charge density increases. This suggests a complex relationship between thresholds and electrode size, possibly due to an inhomogeneous current distribution at the surface of the electrode that evolves during the time course of the stimulus pulse [53], [54]. The trend for thresholds required for eliciting phosphenes in human subjects is less clear.…”

“…Finite element analysis (FEA) of potential and current distributions in galvanic systems has long been studied in the literature [21][22][23][24][25][26][27]. Such studies are often carried out to investigate fundamental effects of electrolyte geometry [26,28,29], electrode kinetics [25], and unique part geometries [21].…”
