AI Technical Summary

Problems solved by technology

[0002] 1) Traditional gel electrodes are prone to sensitization

[0003] At present, the traditional gel electrode adopts the "Ag / AgCl+KCl conductive gel" scheme. Although the signal is better when the user is static, wearing it for a long time will cause skin itching, redness, and blisters due to the irritation of the skin by the electrolyte solution. Allergies, especially for the elderly, young children, and those with sensitive skin;

[0004] 2) Poor signal acquisition quality of conventional fabric electrodes

[0006] ① Movement will lead to different pressures, and different pressures will lead to different contact areas between the conductive cloth and the skin, which will cause the contact conductive area to be unstable. When in contact with the skin, it is easy to cause electrode signal noise;

[0007] ②The fabric electrode cannot be relatively fixed to the skin: the current fabric electrode is integrated on the belt or clothes, and with the movement of the human body, the electrode and the skin will move relative to each other, resulting in electrode signal noise;

[0008] ③The signal acquisition is greatly affected when the user's skin is dry: different skin conditions, the quality of fabric electrode ECG signal acquisition is different

[0009] 3) The traditional snap riveting method is easy to introduce signal noise

[0021] ①The tightness of the ECG suit will cause discomfort to the human body, and in severe cases, it will cause the risk of local thrombosis

[0022] ②It is inconvenient for the user to wet the fabric electrode before use, and as the water evaporates, the contact state between the electrode and the skin will gradually deteriorate;
