“…The heartbeat reflects the heart function of pumping oxygen into human blood over the whole body and removing carbon dioxide out of the lung. The heartbeat is the frequency of cardiac cycles, and the wave detail varies for different ages, body states, and even mental states . Recently, our group has reported rGO‐based pressure sensor with high sensitivity and wearable properties for subtle signals detection .…”

“…Besides, high flexibility and thin thickness would bring a comfortable experience for long‐term monitoring under the human foot. Song et al have prepared a Janus structured pressure sensor via the constructing arch‐shaped concave‐convex microstructures ( Figure a,b) . Using the interlaced stainless steel mesh as the template, the gel matrix was coated on the template and then the GO film.…”

Recently, advancement in materials production, device fabrication, and flexi ble circuit has led to the huge prosperity of wearable electronics for human healthcare monitoring and medical diagnosis. Particularly, with the emergence of 2D materials many merits including light weight, high stretchability, excellent biocompatibility, and high performance are used for those potential applications. Thus, it is urgent to review the wearable electronics based on 2D materials for the detection of various human signals. In this work, the typical graphene-based materials, transition-metal dichalcogenides, and transition metal carbides or carbonitrides used for the wearable electronics are discussed. To well understand the human physiological information, it is divided into two dominated categories, namely, the human physical and the human chemical signals. The monitoring of body temperature, electrograms, subtle signals, and limb motions is described for the physical signals while the detection of body fluid including sweat, breathing gas, and saliva is reviewed for the chemical signals. Recent progress and development toward those specific utilizations are highlighted in the Review with the representative examples. The future outlook of wearable healthcare techniques is briefly discussed for their commercialization. Wearable Electronics

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.
