Comparison of different structures of silver yarn electrodes for mobile monitoring

As preventive healthcare for cardiac patients and risk groups as well as EKG in sports and daily life monitoring are developing, the need to have a monitoring system unencumbered by cables is growing. The usage of conventional electrodes is made unsuitable by the cabling, as this causes artifacts and lowers the user friendliness of the system. The nature of the medical electrodes makes them not suitable for use in general populations where the patient needs an easy way to attach the electrodes. A way to overcome these problems is to use clothing which has the electrodes integrated. One possibility is to use silver yarn as the material for the conductive structure. In this paper we are comparing different electrode structures' response to motion and thus their characteristics to overcome motion artifact problems.
