Electrodes fabricated on a flexible substrate are a revolutionary development in wearable health monitoring due to their lightweight, breathability, comfort, and flexibility to conform to the curvilinear body shape. Different metallic thin-film and plastic-based substrates lack comfort for long-term monitoring applications. However, the insulating nature of different polymer, fiber, and textile substrates requires the deposition of conductive materials to render interactive functionality to substrates. Besides, the high porosity and flexibility of fiber and textile substrates pose a great challenge for the homogenous deposition of active materials. Printing is an excellent process to produce a flexible conductive textile electrode for wearable health monitoring applications due to its low cost and scalability. This article critically reviews the current state of the art of different textile architectures as a substrate for the deposition of conductive nanomaterials. Furthermore, recent progress in various printing processes of nanomaterials, challenges of printing nanomaterials on textiles, and their health monitoring applications are described systematically.

With the rapid development of Internet of Things and miniaturized electronics, the demand for wearable power sources with high reliability and long duty cycle promotes the exploration of wearable thermoelectric generators (TEGs). In particular, textile‐based TEGs that can perpetually convert the ubiquitous temperature gradient between human body and ambience into electrical energy have attracted intensive attention to date. These lightweight and three‐dimensional deformable TEGs comprised of fibers, filaments, yarns, or fabrics offer unique merits as wearable power source in comparison with conventional TEGs. In this review, we systematically summarize the state‐of‐the‐art strategies for textile‐based TEGs, including the structure design, fabrication, device performance, and application. Existing critical issues and future research emphasis are also discussed.

Research of flexible sensors for human wearable health monitoring are of paramount importance. In view of the problems of traditional sensors, such as complexity, low sensitivity, insufficient strain, short service life and incompatibility with human body, the research progress of Graphene-based flexible sensors in wearable health monitoring is systematically introduced. Benefitting from the commendable flexible mechanical properties and high durability, flexible Graphene-based sensors promote its applications in motion detection, body temperature monitoring, sweat ion real-time monitoring, voice recognition, pulsebeating, and respiration detection. The challenges and prospects of the application of Graphene-based flexible sensors in wearable health monitoring are pointed out. It is expected that most current research, which is still experimental, will need several more years of study before it becomes widely used. In the future, more attention should be paid to the lack of flexibility and high sensitivity of Graphene, the preparation of high purity Graphene, the application of composite materials and the development of advanced technology.
