Research on Real-time Body Fluid Analysis Based on Flexible Wearable Electrochemical Sensor for Health Monitoring

With the rapid development of the Internet of things and medical technology, wearable electrochemical sensors, as an innovative device integrating biotechnology and electronic information technology, have received extensive attention and research in recent years. Compared with other vital signs, the metabolic substances produced in body fluids can be relatively easily collected non-invasively, which has great potential in health diagnosis, exercise monitoring and other aspects. Exercise health monitoring is a major application area for indicator monitoring of sweat parameters [1]. The most commonly used technology is based on electrochemical principles. This paper will elaborate on the relevant progress of the body fluid sampling method and summarize it based on the electrochemical source. The evaluation of wearable sensor performance indicators, the latest progress and related applications, and further exploring its current limitations and future development trends.
