ABSTRACT
Nanocomposite-based flexible wearable sensors have a high potential to become health diagnostic tools used by the public due to their suitable size, ease of use, fast response time, and affordability. Wearable sensors can replace extensive and time-consuming diagnostic devices in some cases. In this chapter, hydrogel and graphene-based materials, as well as the technologies used for manufacturing high-performance wearable sensors, are discussed. Regarding the materials used, it is recommended to apply composite materials to provide the required characteristics of wearable sensing materials. Also, the more practical technologies to manufacture wearable sensors, including 3D printing, applying nanogenerators, and methods of improving conductivity, are comprehensively explained. Finally, the challenges that flexible wearable sensors face are discussed.
