Wearable multimodal sensors could enable the continuous, non‐invasive, precise monitoring of vital human signals critical for remote health monitoring and telemedicine. Atomically thin materials with intriguing physical characteristics, rich chemistry, and extreme sensitivity to external stimuli are attractive for implementing high‐performance wearable sensors. Despite the increased interest and efforts in 2D materials‐based wearable sensors, reducing the manufacturing and integration costs while improving the product performance remains challenging. Previous review articles provided good coverage discussing the material and device aspects of 2D materials‐based wearable devices. However, few reviews discussed the status quo, prospects, and opportunities for the scalable nanomanufacturing of 2D materials wearable sensors for health monitoring. To fill this gap, the recent advances in 2D materials‐based wearable health sensors are reviewed. The structure design, fabrication processing, the mechanisms of 2D materials‐based wearable health sensors, and their applications for human health monitoring are discussed. More significantly, a systematic discussion of the state‐of‐the‐art and technological gaps for enabling future design and nanomanufacturing of 2D materials wearable health sensors are provided. Finally, the challenges and opportunities associated with the scalable nanomanufacturing of 2D wearable health sensors are discussed.

Conductive nanomaterials have recently gained a lot of interest due to their excellent physical, chemical, and electrical properties, as well as their numerous nanoscale morphologies, which enable them to be fabricated into a wide range of modern chemical and biological sensors. This study focuses mainly on current applications based on conductive nanostructured materials. They are the key elements in preparing wearable electrochemical Biosensors, including electrochemical immunosensors and DNA biosensors. Conductive nanomaterials such as carbon (Carbon Nanotubes, Graphene), metals and conductive polymers, which provide a large effective surface area, fast electron transfer rate and high electrical conductivity, are summarized in detail. Conductive polymer nanocomposites in combination with carbon and metal nanoparticles have also been addressed to increase sensor performance. In conclusion, a section on current challenges and opportunities in this growing field is forecasted at the end.
