Year: 2026
Type: dataset
Abstract: This MATLAB script calculates and visualizes the geometry-dependent access resistance of planar and recessed circular microelectrodes.The model separates the total access resistance into two contributions: Raccess=Rspread+Rrecess, where Rspread describes the spreading resistance of a circular electrode and Rrecess describes the additional resistance introduced by an insulating recess above the electrode. For a circular electrode with radius r, the spreading resistance is approximated as Rspread=4rρ, while the resistance of a cylindrical recess with depth L is approximated as Rrecess=πr2ρL. The resulting access resistance is therefore Raccess=4rρ+πr2ρL. The script is intended to investigate how electrode diameter and insulation recess depth affect access resistance, with particular emphasis on the scaling behaviour of recessed microelectrodes at small dimensions.
