Use of graphene-based fabric sensors for monitoring human activities

The emerging field of textile-based sensors has created a potential platform for devising flexible sensors capable of human body-incorporated sensing and control. Their uses have increased significantly in recent years due to their high flexibility, easy comfortability and high sensitivity. This paper shows a substantial review of the use of graphene/textile prototypes for human activity sensing applications. Different kinds of natural and synthetic fibers have been integrated with nanomaterials to form thin-film sensors. Among the conductive elements with whom these textiles have been conjugated, graphene has been pivotal due to its excellent electrical and mechanical characteristics. Graphene has been done in pure, oxide and composite forms to form electrodes with high selectivity towards the chosen application. The main purpose of this review is to highlight the differences in the qualities of the graphene/fabric-based sensors in terms of their analytical responses based on the sensor substrates and fabrication techniques. The paper also provides a critical analysis of the challenges existing in the current scenario and provides some of the possible remedies that can be considered. (c) 2021 Elsevier B.V.
