MONITORING OF ELECTRODE DEGRADATION DURING CURRENT-CONTROLLED STIMULATION

Summary

The project aims to identify and discriminate the mechanisms causing electrode degradationduring electrical neural stimulation, even when operated within "safe limits." By combining in situmonitoring of the electrode's potential on the electrochemical scale during current-controlledstimulation with a phenomenological description of the effects on a submicron level, theelectrochemical reactions during different stages of degradation will be assessed. The approachbenefits from the IMBIT's Soft-FIB and a newly developed high-speed electrometer amplifier,allowing electrochemical potential monitoring parallel to current-controlled stimulation.
