This report describes the production, characterization and performance evaluation of a Graphene-Nylon composite material and its application as an ECG electrode material. This research is motivated by the global prevalence of Diabetes and associated cardiovascular disease (CVD), and the need for improved cardiac monitoring systems. The sensors described herein are seen as good candidates for incorporation to a Constant monitoring system (CMS) for ECG activity, connected via the Internet of Things (IoT). This composite material acts as a conductive interface between sensor electronics and the skin surface, conducting bioelectric signals from the heart. The composite is produced by applying a reduced graphene oxide (rGOx) “coating” to nylon fabric. The electrical and mechanical characteristics of graphene, combined with its strong physical adhesion to nylon result in a tough and practical composite product. Additionally, the electrical conductivity of the composite can be tuned as-desired by applying multiple “coats” of graphene.
