Advances in wearable flexible electrochemical sensors for sweat monitoring: A mini-review
Abstract
Achieving health monitoring and chronic disease monitoring of the human body is a frontier topic in the world, including the scientific fields of materials science, information technology, electronics, and analytical chemistry. Wearable devices that continuously acquire physical signals such as temperature, pressure, and stress to achieve real-time monitoring of human activity have been commercialized. However, wearable sensors that continuously monitor various chemicals in human body fluids and exhaled breath still face many problems, such as the flexibility, sensitivity, accuracy and the fit of the sensor to human skin. This mini-review introduces the advantages of flexible wearable sensors applied to sweat monitoring, especially the research progress of flexible wearable sensors in monitoring glucose, lactate, pH value and various markers in sweat. At the same time, this review also analyzes the current shortcomings and limitations of flexible wearable sensors. We believe that future flexible wearable The future development of flexible wearable sweat sensors should be in the direction of low cost, easy manufacturing, high selectivity and sensitivity.
