“…Metabolites, such as lactate, glucose, uric acid, and electrolytes (e.g., K + , Na + , and Cl − ) from human secretion are important indicators of human health status. [ 894–897 ] Among different human secretions, sweat is among the most accessible ones by noninvasive sampling techniques (e.g., using an epidermal microfluidic device, [ 898,899 ] letting sweat naturally drip off from the skin, [ 900,901 ] and collecting the water from whole body wash [ 900,902–904 ] ). Sweat can be collected to provide human health information for medical diagnostics.…”

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.

“…Small, tooth mounted sensors in which the properties of reflected radio frequency (RF) waves are modulated by the presence of certain chemicals in saliva can detect the consumption of salt and alcohol in real time (45). Similarly, tattoo like epidermal sensors that attach to, and stretch and flex with the skin can detect a variety of metabolites in an individual's perspiration that relate directly to their diet (46). For these devices, it is important that metabolites detected are specific to food intake, and not conflated with endogenous metabolites produced by the body as a result of eating.…”

Established methods for nutritional assessment suffer from a number of important limitations. Diaries are burdensome to complete, food frequency questionnaires only capture average food intake, and both suffer from difficulties in self estimation of portion size and biases resulting from misreporting. Online and app versions of these methods have been developed, but issues with misreporting and portion size estimation remain. New methods utilizing passive data capture are required that address reporting bias, extend timescales for data collection, and transform what is possible for measuring habitual intakes. Digital and sensing technologies are enabling the development of innovative and transformative new methods in this area that will provide a better understanding of eating behavior and associations with health. In this article we describe how wrist-worn wearables, on-body cameras, and body-mounted biosensors can be used to capture data about when, what, and how much people eat and drink. We illustrate how these new techniques can be integrated to provide complete solutions for the passive, objective assessment of a wide range of traditional dietary factors, as well as novel measures of eating architecture, within person variation in intakes, and food/nutrient combinations within meals. We also discuss some of the challenges these new approaches will bring.
