Embodiment 1

[0065] Prepare a graphene oxide aqueous solution with a concentration of 5 mg / ml, install the Buchner funnel on the suction filter bottle, and then put the graphene oxide solution with a thickness of 5 mm, a circular shape, a diameter of 20 mm, and a density of 25 kg / m 3 Cover the bottom of the Buchner funnel with a flexible sponge, turn on the vacuum pump for suction filtration, and keep the negative pressure in the Buchner funnel at 2.0×10 4 Pa, then slowly pour the graphene oxide aqueous solution with a concentration of 5 mg / ml on the flexible sponge until the suction filtration is completed. The shape of the flexible sponge can also be set to a circle, an oval, a polygon or other beautiful patterns. The flexible sponge adsorbed by graphene oxide was placed in a vacuum oven and dried at 50 °C for 3 h to obtain a graphene oxide-flexible sponge composite. The graphene oxide-flexible sponge composite was impregnated in 0.17mol / L NaBH 4 in aqueous solution, stirred slowly at...

Description

technical field [0001] The invention relates to a personal health monitoring and medical electronic equipment, in particular to an anti-interference electrocardiogram detection system, a detection method, a special flexible graphene electrode and its preparation method and application. Background technique [0002] The ECG signal directly reflects the working state of the heart. Abnormal ECG signals appear randomly, the time is not fixed, and the duration is relatively short. Existing clinical electrocardiographs only last for a few minutes each time, and the amount of information is very limited, making it difficult to effectively capture abnormal ECG signals. The dynamic electrocardiogram can continuously record the heart condition and is an important basis for discovering abnormal heart activity. In daily life, using wearable ECG monitoring equipment, without hindering daily work and life, the wearer can detect ECG signals anytime and anywhere at home, work and outdoor t...
