Preparation method of spinning electrode used for testing electrocardiosignal

Abstract

The invention relates to a preparation method of a spinning electrode used for testing an electrocardiosignal. The preparation method comprises the steps of adding dodecyl benzene ring perborate into distilled water to obtain a solution A, adding ammonium persulfate to obtain a solution B, placing a base fabric into the solution B to obtain an infiltration solution C, stirring and infiltrating under the environment of ice-water bath, adding a pyrrole monomer into the solution C to obtain a solution D, reacting for 1-2 hours under the environment of ice-water bath, taking out the base fabric, washing and drying to obtain a conductive base fabric; adding a dopant into the distilled water to obtain a solution E, and adding a pyrrole monomer to obtain a solution F; adding the solution F into an electrolytic tank, taking the conductive base fabric as a working electrode for carrying out electrochemical polymerization reaction, washing and drying to obtain the spinning electrode, wherein a reference electrode is a Ag / AgCl electrode, and a counter electrode is a stainless steel wire net. The spinning electrode prepared by the preparation method provided by the invention is small in electrode impedance, good in flexibility and simple, fast and efficient in manufacturing process, has air and water vapor permeability, and cam be used under the condition that a conductive paste is not used.

Description

technical field [0001] The invention belongs to the field of preparation of electrodes for testing electrocardiographic signals, in particular to a preparation method of textile electrodes for testing electrocardiographic signals. Background technique [0002] Long-term real-time monitoring of ECG signals has gradually become an effective technical means to evaluate cardiovascular function. On the premise of not affecting people's daily activities, in order to realize long-term monitoring of ECG signals, in addition to the need for portable monitoring instruments, ECG electrodes suitable for long-term use are also one of the key conditions. At present, the electrocardiogram electrodes used clinically are Ag / AgCl electrodes with conductive paste. Long-term use will bring the following problems: (1) Since the electrode material does not have air and moisture permeability, long-term use will cause skin discomfort; (2) ) The conductive paste will gradually dry up under long-ter...

AI Technical Summary

Problems solved by technology

At present, the electrocardiogram electrodes used clinically are Ag / AgCl electrodes with conductive paste. Long-term use will bring the following problems: (1) Since the electrode material does not have air and moisture permeability, long-term use will cause skin discomfort; (2) ) The conductive paste will gradually dry up under long-term use conditions, causing a sharp change in the contact resistance between the electrode and the skin, affecting the stability of the ECG signal; (3) The existence of the conductive paste is also a factor for skin allergies and other discomfort reactions

Although this method can produce fabrics with good conductivity, it has high requirements for printing equipment and conductive ink. At the same time, the conductive layer is only sprayed on the surface of the fabric, which is easy to fall off and has poor firmness.
