Textile application in bio-potential recording used for medicinal purposes: an overview

Bio-potential signals in the form of eeg and ecg are the two critical health indicators that are directly suited for long-term monitoring using bio-sensors. The conventional wet adhesive ag/agcl electrodes are the most commonly and commercially used in clinical applications today for these purposes. They provide an excellent signal but are cumbersome and irritating while operated with gels, adhesives and even causes certain skin problems when come in direct contact with the outer dry layer of skin. Invention of textile electrode is the outcome of the search for suitable option for this classical technique. Various textile structured electrodes developed in the course have shown a bright sign of improvement in work practices. Successful development and commercialization of an interactive textile based bio-potential device can leave a profound influence on health monitoring system in the society. This paper extends platform for the critical theoretical review of overall developments took place in textile structured electrodes used for long term monitoring of cardiac issues.
