Electrode materials dissolution testing

This chapter introduced several methods for analyzing the electrochemical properties of neuro-stimulation electrodes. Cyclic voltammetry is a generic technique that shows the oxidation/reduction potentials of a material, thereby revealing important electrode behavior properties. Furthermore, the impedance spectra and the electrode potential can reflect the surface area and the charge-injection limit of the electrode, respectively. Lastly, to determine their functional lifetimes, electrodes must be subjected to long-term dissolution testing.
