Abstract
This paper focuses attention on ensembles of microelectrodes, which enables measurement of a reasonable large current. A numerical simulation, using the explicit finite difference method is employed for solving the diffusion equations with the appropriate boundary and initial conditions. To save computation time, a two-dimensional expanding grid is used, similar to the one-dimensional grid proposed by S. W. Feldberg. The grid is fine in regions of rapid changes of the concentration (near the surface of the electrode in the perpendicular direction and at the boundary between the active and inactive regions in the parallel direction) and coarse in regions where the rate of change of concentration is low.
