Embodiment 1

[0027] Embodiment 1: The present invention relates to a preparation method of a honeycomb electrode patch, comprising the following steps:

S1. Preparation of transparent self-adhesive conductive hydrogel;

S2, making honeycomb flexible electrode patches (such as figure 1 shown);

S3, preparing the honeycomb electrode patch of transparent self-adhesive high-conductivity hydrogel.

[0028] The step S1 is specifically the preparation of transparent self-adhesive high conductive hydrogel: (name of example 1: PVA-HEDP-HPAA-10%)

S1-1: Accurately weigh 3.00 g of polyvinyl alcohol (PVA), dissolve it in 15 ml of deionized water, and react at 105° C. for 2 hours to obtain a polyvinyl alcohol solution.

[0029] S1-2: In the above-mentioned polyvinyl alcohol solution, add 8.5ml of hydroxyethylidene diphosphonic acid (HEDP) and 1.5ml of 2-hydroxyphosphonoacetic acid (HPAA), that is, the mass concentration is 10%, after fully stirring , use ultrasonic degassing to remove the bubbles o...

Embodiment 2

[0053] The second step: in the above-mentioned polyvinyl alcohol solution, add 7ml of hydroxyethylidene diphosphonic acid (HEDP), 3ml of 2-hydroxyphosphonoacetic acid (HPAA), that is, the mass concentration is 20%, after fully stirring, use Ultrasonic degassing to remove the bubbles of the solution, and react for 2 h under the condition of an oil bath at 95 °C to obtain a precursor solution (hot sol solution).

[0054] The third step: inject the above solution into a laboratory-made silica gel mold and freeze at -30 °C for 50 h to obtain a hydrogel.

[0055] The fourth step: deionize the prepared hydrogel to wash off the residual unreacted substances, and purge the surface of the gel with nitrogen to dry the surface moisture, and finally obtain a highly conductive self-adhesive transparent hydrogel. The prepared hydrogel was packaged in a sealed bag to prevent moisture loss.

Embodiment 3

[0066] Step 2: In the above polyvinyl alcohol solution, add 5.5ml of hydroxyethylidene diphosphonic acid (HEDP) and 4.5ml of 2-hydroxyphosphonoacetic acid (HPAA), that is, the mass concentration is 30%, and after fully stirring , use ultrasonic degassing to remove the bubbles of the solution, and react for 1 h under the condition of 105 ℃ oil bath to obtain a hot sol solution.

[0067] The third step: inject the above solution into a silicone mold made by the laboratory, and freeze at -40 °C for 24 hours to obtain a hydrogel.

[0068] The fourth step: deionize the prepared hydrogel to wash off the residual unreacted substances, and purge the surface of the gel with nitrogen to dry the surface moisture, and finally obtain a highly conductive self-adhesive transparent hydrogel. The prepared hydrogel was packaged in a sealed bag to prevent moisture loss.

Description

technical field [0001] The invention relates to a preparation method of a honeycomb electrode patch, a honeycomb electrode patch and application, and relates to a gel electrode material and its application field. Background technique [0002] Electrophysiological signals are an important indicator of human exercise health. Among all physiological signals, electrical signals accompany the human body's daily activities from thought to muscle movement to digestion. The activities of organs, tissues and neurons are all related to electrical potential. [0003] Electrophysiological signals are mainly generated by changes in the membrane potential of electroactive cells. Electrophysiological signals mainly include: EEG signal, ECG signal, EMG signal. Heart-related diseases, such as arrhythmia, myocardial infarction, etc., can be found in time by monitoring ECG signals; brain-related diseases, such as epilepsy, can be found in time by monitoring EEG signals; The body surface defo...
