This book provides readers with basic principles of the electrochemistry of the electrodes used
in modern implantable neural prostheses. The authors discuss the boundaries and conditions in
which the electrodes continue to function properly for long time spans which are required when
designing neural stimulator devices for long-term in vivo applications. Two kinds of electrode
materials titanium nitride and iridium are discussed extensively both qualitatively and
quantitatively. The influence of the counter electrode on the safety margins and electrode
lifetime in a two electrode system is explained. Electrode modeling is handled in a final
chapter.
