Align MWCNT/GNPs/PDMS based nanocomposite dry ECG electrodes for ECG recordings

Abstract

This work focuses on the fabrication and testing of highly conductive polymer electrodes to measure the biomedical signals known as an Electrocardiogram (ECG). When doing this, optimal skin contact is considered. Align Multiwalled Carbon Nanotubes (AMWCNT), Graphene Nanoplates (GNPs), and Polydimethylsiloxane (PDMS) were used to fabricate the electrodes for continuous ECG monitoring. Sonication and magnetic stirring were used to disperse the mixture. The conductance of the PDMS/GNPs/AMWCNT electrodes were measured using a digital multimeter and were compared with that of standard silver-silver chloride (Ag/AgCl) electrodes. The current study showed that real-time monitoring achieved by an internet of things (IoT) systems with microcontroller.
