(8) Conversely, at all other electrodes, faradaic reactions compete to some extent with an osteogenic response.
(9) Significant differences observed between platinum-iridium and stainless-steel electrodes seem to suggest that faradaic results play little or no role in the osteogenic response at the platinum-iridium cathode.
(10) Faradaic signals due to cycles of continuous oxidation and reduction of dopamine at the tip of the electrode can be observed superimposed on a fixed charging current.
(11) However, the insertion of a constant phase element (CPE) in the non-faradaic branch of the equivalent circuit offers a new scope for interpretation as the circuit provides an m-parameter corresponding to the degree of distortion.
(12) Capacitor electrodes offer the potential for the safest method of stimulation of neural tissue because they operate without any faradaic process occurring at the electrode-electrolyte interface.
(13) The effects of heat transfer through the highly conductive metal electrode and irreversible Faradaic reactions have been considered.
Faradic
Definition:
(a.) Of or pertaining to Michael Faraday, the distinguished electrician; -- applied especially to induced currents of electricity, as produced by certain forms of inductive apparatus, on account of Faraday's investigations of their laws.
