Description

MODELING THE DOUBLE LAYER FORMATION FOR ELECTRICAL NEUROSTIMULATION AT THE ORGANIC POLYMER - ELECTROLYTE INTERFACE

Electrical double-layer formation attracted significant interest more than a century ago and remains fundamentally involved in capacitive external stimulation of biological tissue. This work focuses on the study of the double layer characteristics at the interface formed between an electrolyte and polymer structures of organic photocapacitors, being of great interest for minimally invasive neurostimulation. Based on a combination of the Helmholtz and Gouy-Chapman methods, the Stern model is applied in COMSOL Multiphysics to investigate this electrical double layer formation. Simulations nicely highlight the importance of electrolyte concentration used and good cell adhesion.
