Wearable Electrochemical Sensors for the Detection of Organic Metabolites and Drugs in Sweat

As a kind of human body fluid, sweat contains a large number of substances closely related to human metabolism. Analysis of the sweat components can offer important information for medical diagnosis and health management. Traditional methods for sweat analysis often require large-scale biochemical analysis equipment, which are not conducive to the timely and in-situ monitoring of sweat components. Wearable sensors can be used to detect metabolites in sweat, saliva and tears and avoid the damage caused by blood detection. Electrochemical sensors can convert the target concentration into electrical signals. In recent years, the breakthrough of wearable auxiliary technology has helped the development of electrical sensors for the real-time analysis of sweat components. In this work, we summarized the wearable electrical devices for analysis of organic metabolites and drugs in sweat.
