title: Characteristic properties of implantable Ag/AgCl- and Pt-electrodes.
abstract: Traditional potential measurement from the surface of skin, e.g. ECG, has the shortcoming of motion artifact and possible power-line interference. Further problems in the measurement can occur from the time and place dependency of the measurement. All of these problems can be avoided by using an implantable measurement device. With an implantable device one can access many such quantities in man where there is no access with traditional measurement setups. This research paper deals with noise measurements of implantable electrodes in saline. Electrode characteristics are also investigated. More specific electrode-electrolyte interface capacitance and resistance are determined from some of the electrodes studied.
