EVALUATION OF THE QUALITY OF ELECTRODE CONTACT WITH A SKIN SURFACE

摘要

An instrument that utilizes body contact electrodes evaluates the quality of the connections made between the electrodes and the body. An electrode contact quality evaluation circuit performs the quality evaluation, such as by determining contact impedances for the electrodes. The corresponding contact quality of each electrode is conveyed to the user.
