Embodiment 1

[0031] Embodiment 1: The gas-permeable flexible glucose sensor is used as an embodiment to describe in detail below.

[0032] Such as figure 1 As shown, the air-permeable flexible glucose sensor prepared by the method of the present invention is fabricated on a porous polyimide membrane 3 that conforms to the epidermis of the human skin, and is used for continuous monitoring of blood glucose concentration in the human body. The sensor is composed of a reference electrode 1.1, a working electrode 1.2 and an auxiliary electrode 1.3. The reference electrode 1.1, the working electrode 1.2 and the auxiliary electrode 1.3 are respectively connected to external devices through a signal line 2.

[0033] The reference electrode 1.1, the working electrode 1.2 and the auxiliary electrode 1.3 jointly constitute an electrochemical sensor for detecting the glucose concentration in body fluids (such as sweat, interstitial fluid, etc.), and can realize the glucose concentration detection unde...

Abstract

The invention discloses an air-permeable flexible skin electrochemical sensor, a preparation method of the air-permeable flexible skin electrochemical sensor, and application. The air-permeable flexible skin electrochemical sensor is mainly composed of a porous flexible substrate layer and an electrochemical sensor from bottom to top; a porous polyimide film has a certain anti-crimp function, canbe conformal with skin, has good skin fit, and simultaneously, has good air permeability; sweat evaporation is facilitated; skin irritation is prevented; accumulation of detection substances is avoided; the detection accuracy is increased; high temperature and high pressure are not required in the preparation method of the porous polyimide film; the requirement of film making equipment is simple;the method has the advantages of being high in efficiency, low in cost, one-step, free from a template and the like; and the sensor in the invention has the advantages of being air-permeable, flexible, good in skin fit and the like, cannot irritate skin while being worn for a long time, and can be used for wearable flexible skin electronic equipment.

Description

technical field [0001] The invention belongs to the field of electrochemical sensors, in particular to a gas-permeable flexible electrochemical sensor and its preparation method and application. Background technique [0002] With the development of materials and manufacturing technologies, wearable flexible skin sensors have attracted widespread attention from academia and industry. These wearable flexible skin sensors can be used to continuously monitor health data, including skin temperature, ECG signals, Myoelectric signals, as well as the concentration of various substances in physiological activities, etc., researchers have also achieved certain results in wearable flexible skin sensors. [0003] Although the flexible skin sensor can be well used in the monitoring of human health data, in order to improve the signal accuracy and detect data in real time, the sensor and the skin need to be in close contact at all times, so in addition to different sensing performance, it...
