ABSTRACT
Wearable health monitoring devices are emerging rapidly and attracting wide attention due to the advancement in nanomaterial and nanofabrication. Nanocarbon materials have low density and their superior electrical, mechanical, thermal and chemical properties enabled them as a promising electrode material for flexible and wearable health monitoring. Carbon nanotube and graphene are the most used nanocarbons for various wearable applications and have outstanding characteristics to be used for the health monitoring system. Skin temperature and different electrophysiological signals such as electroencephalogram (EEG), electrocardiogram (ECG), and electromyogram (EMG) are generated by the activities of the brain, heart and muscle and can provide critical health information. It is crucial to continuously monitor skin temperature and these electrophysiological signals for high-risk patients and early detection of diseases. Electrophysiological sensors are attached to the human body for wearable monitoring of these bio-signals and skin temperature. This chapter discusses different carbon nanostructures, electrode fabrication, sensing mechanism and requirements, and application of graphene and carbon nanotube for wearable health monitoring.
