Fabrication of PPy/PVC Electrodes for ECG Monitoring

Abstract

The detection of biosignals includes the use of biomedical electrodes. As the obtention of biosignals is vital for medical diagnosis, electrodes with good performance must be used. In this paper, electrodes made of Polypyrrole (PPy) and Polyvinyl chloride (PVC) were fabricated in order to record ECG signals. Besides, a methodology of their fabrication is presented as well as a comparison between the ECG signal measured with commercial Ag/AgCl electrodes and PPy/PVC electrodes. The results showed a good performance of the PPy/PVC electrodes compared to the commercial ones, making this type of polymeric electrodes a very reliable tool to acquire any type of biosignal.
