Sweat, graphene, biosensors, human metabolism.Abstract
Sweat is a biofluid of great significance, 99% of which is water, while the rest consists of ions, metabolites, hormones and other substances, which provide extremely rich chemical information about biological metabolism and can be used to reflect the state of the body's bodily functions, making it an ideal sample of body fluids for monitoring. Graphene-based wearable sensor technology obtains unique metabolic information through continuous detection of sweat, enabling personalized application to the human body. The intention of this paper is to first introduce the concept of sweat sensor and its working principle by introducing the extraction method of glucose from sweat, which exposes the shortcomings of the current situation of scientific analysis of the human body, i.e., low personalization of detection, low sensitivity of detection, and high cost of detection. The advantages of carbon-based materials such as graphene are then introduced, leading to the derivation of methods to further improve the sweat sensor and seek to optimize its performance.
