13 - Advanced wearable microfluidic electrochemical sensors based on 2D materials

Abstract

Wearable flexible sensors with multiplex analytic capabilities and integrated microfluidic systems are emerging as a novel concept to assess the state of human health. These sensors have enormous promise in fields like clinical medicine monitoring and athletic performance monitoring. To precisely gather a range of physiological data, such as metabolite information, electrolyte balance, and sweat loss, well-designed microfluidic sensors can be attached to the skin's surface. 2D materials are a strong candidate for wearable microfluidic sensor applications due to their attractive electrochemical and electrical characteristics with a variety of structural properties and processing methods. Therefore, both low-cost point-of-care analytics and sophisticated biological/chemical analysis can be performed in a well-controlled microenvironment using these two-dimensional material-based wearable microfluidic devices. The potential use of different 2D materials for microfluidic wearable sensors in a range of medical and environmental applications is critically examined in this chapter. Finally, the possibilities for 2D materials in terms of long-term viability and business concerns are examined.
