Integrated flexible wearable sensor with multi-component sweat detection

Abstract

The invention relates to an integrated flexible wearable sensor with multi-component sweat detection, comprising a GOx electrode, a Lox electrode and an Ag / AgCl electrode; the GOx electrode is used for testing responses of sugar contents in sweat glucose and human blood; the Lox electrode is used for testing lactates in sweat to reflect pressure-derived anemia, skin temperature and various diseases; the Ag / AgCl electrode is used a reference electrode and counter electrode for the GOx electrode and the Lox electrode so as to correspondingly reflect the magnitude of generated current that is directly proportional to glucose and lactate contents in sweat; the Ag / AgCl electrode is used as a reference electrode and counter electrode for the GOx electrode and the Lox electrode so as to correspondingly reflect the magnitude of the generated current that is directly proportional to glucose and lactate contents in sweat. A multi-electrode sensor is produced; correction for a temperature sensoris provided; current signal adjustment, Bluetooth accessories on the sensor, a cellphone APP and a cloud database help provide precise and efficient real-time detection, reading and storage for multiple components in sweat, and a user can know his or her physiological information at any moment.

Description

technical field [0001] The invention relates to the field of biochemical sensors, and more specifically, the invention relates to an integrated flexible wearable sensor for multi-component sweat detection. Background technique [0002] Biosensors have been widely used in fields such as medicine, health and sports. However, the common sensors currently on the market, such as the most widely used blood glucose meter, will cause pain to the user, and cannot realize real-time detection. Wearable flexible sensors can be carried around to detect various physiological indicators of the human body in real time. The wearable sensors currently available on the market can only detect physical activities (such as steps) or vital signs (such as heartbeat) of the human body, but cannot provide information on the health status of the human body from a molecular perspective, which makes it have certain limitations. sex. [0003] Sweat is an important secretion of human metabolism, rich i...

Problems solved by technology

However, the acquisition and detection of sweat that have been achieved so far are separated. For different substances in sweat, the analysis requires the use of a variety of large-scale laboratory equipment, so it is impossible to provide a real-time analysis of body status.

The predecessors have also tried the design of the sensor used to detect sweat, and there are many unsolved problems. For example, due to the rich chemical substances contained in sweat, it is impossible to use a single electrode for detection; the chemical substances will interfere with each other, so that the obtained poor signal accuracy
