DYNAMIC ELECTROCHEMICAL SIMULATION AND TESTING OF MICROMACHINED ELECTRODES FOR NEURAL STIMULATION

摘要

The dynamic distribution of electrode voltage and current is simulated using SPICE and ANSYS. In contrast to previous steady-state simulations, transient mode simulations reported in this work incorporate capacitive electrode elements, and show that the electrode surface exhibits high current uniformity. Such result implies that high-aspect-ratio topologies can be employed to increase the electrode charge injection limit without localized current crowding and corrosion.
