Reduced graphene oxide for the design of electrocardiogram sensors: Current status and perspectives

Abstract

Electrocardiogram (ECG) provides valuable information about the heart. By monitoring ECG data, doctors may be able to predict heart problems for swift treatment and better patient outcome. Clinically accepted ECG collection relies on gel-type adhesive electrodes, but to take advantage of increasingly capable home diagnostic systems, robust, comfortable, and affordable dry-type electrodes are desirable. In this chapter, we describe the production and validation of an ECG sensor built from reduced graphene oxide (rGOx) -coated nylon fabric. The graphene coating is applied multiple times to optimize the electrical characteristics of the composite fabric. The performance of the new electrode is compared to standard gel-type electrodes.
