Preparation of fabric strain sensor based on graphene for human motion monitoring


To date, wearable sensors are increasingly finding their way into application of healthcare monitoring, body motion detection and so forth. A stretchable and wearable strain senor was fabricated on the basis of commercially available spandex/nylon fabric by the integration of conductive graphene network. Specifically, a simple graphene oxide dip-reduce method that enabled scalable fabrication pathway was employed. The good recovery of the graphene-coated fabric led to consistent resistance values despite the strain applied on the fabric and exhibited high gauge factor around 18.5 at 40.6% strain. Moreover, the graphene-coated fabric sensor could detect human motions such as finger bending with acceptable mechanical properties against un-coated fabrics, indicating that it has huge potential in wearable sensors applications.
