Corrections to Compact Nonlinear Model of an Implantable Electrode Array for Spinal Cord Stimulation
Abstract
Reference [1] describes the construction of a model of the electrode-electrolyte interface and the surrounding electrolyte for a platinum-electrode array used in Spinal Cord Stimulation (SCS) applications. In that paper, a key advancement was a compact equivalent-circuit model of a constant phase element (CPE) that can be entered into the SPICE simulator. The authors of [1] relied heavily on mathematics taken from [2] by Morrison. While the mathematics in [2] produces a zero error in phase, it results in a finite error in magnitude. Morrison makes no claim about this error in the magnitude approximation, which escaped the authors of [1]. Morrison does not explain how he arrived at (18), and (19) proves to be incorrect.
