Conductive hydrogel paper-based equipment for synchronously monitoring physiological and biochemical parameters

Abstract

The invention discloses conductive hydrogel paper-based equipment for synchronously monitoring physiological and biochemical parameters. The self-assembly of the porous PEDOT: PSS hydrogel on the paper fiber is realized, so that the paper fiber has good conductivity and good water wettability, efficient electron transmission and substance diffusion are realized, and it is ensured that the paper fiber can be used as a low-impedance electrocardio sensor and a high-sensitivity electrochemical sensor. Meanwhile, due to the spontaneous capillary flow effect, the filter paper can serve as a hydrophilic channel of paper microfluid and is used for capturing and analyzing sweat. During exercise testing, the hydrogel paper patch is attached to the surface of skin to collect electrocardiogram data and the concentration of a target substance in sweat, and therefore non-invasive monitoring is achieved. According to the equipment, a flexible, low-cost and multifunctional paper analysis device can be realized and is used for synchronously monitoring physiological and biochemical signals in the movement process.

Description

technical field [0001] The invention belongs to the field of integrated monitoring equipment, and in particular relates to an integrated conductive hydrogel paper-based equipment for synchronous detection of physiological and biochemical parameters. Background technique [0002] During sports activities, the physiological and biochemical signals of the human body will undergo complex changes, especially during long-term and long-distance sports, athletes are prone to water loss, hypoglycemia and arrhythmia, which are risk factors for sports injuries. At present, wearable devices on the market can detect physiological signals during exercise, but complex but valuable changes in biochemical indicators are often overlooked, and these changes in biochemical indicators are important parameters of the body's response during human exercise. Therefore, this requires simultaneous monitoring of physiological and biochemical indicators during physical activity. [0003] Integrated dev...

Problems solved by technology

However, existing research on paper-based devices mainly focuses on modifying conductive materials on paper, such as metal deposition, and printing conductive materials, and does not modify paper

Under the microscope, the modified material and the substrate are independent of each other, and the fusion of the substrate and the electrode has not been achieved

Furthermore, paper-based devices with fully integrated physiological and biochemical electrodes and microfluidics have not been reported yet.
