Problems solved by technology

In order to obtain accurate physiological signals and reduce the interference of human body movement on the signal, the conductive hydrogel materials used in wearable devices must have good adhesion to the skin. Therefore, a lot of research has focused on how to improve the conductivity of hydrogels. and adhesiveness, while ignoring the peeling problem of the material and the skin, which makes the residue caused by incomplete peeling from the skin after use of the device easy to cause psychological discomfort to the user, the life of the device is short, and even the skin is damaged due to excessive adhesion to the skin. cause damage
Through biomimetic research (such as octopus sucker, gecko feet, burdock seeds, etc.), although reversible adhesion between interfaces has been achieved, they are mostly suitable for use on rough flat substrates, free-form and soft surfaces (such as skin) The effect is not ideal

Description

technical field [0001] The invention belongs to the technical field of hydrogel preparation, and in particular relates to a preparation method and application of a novel hydrogel electrode patch that can be used for health monitoring. Background technique [0002] With the rapid development of artificial intelligence, wearable flexible electronic devices can realize real-time monitoring of human body movement information and physiological information (such as EMG, ECG, EEG), and have important applications in health detection, human-computer interaction and other fields. Hydrogels are constructed from 3D microstructured network polymers. The materials are soft and elastic, and have good biocompatibility and skin-adherence. Therefore, the development of conductive hydrogels with sensing functions has become a current research hotspot. In order to obtain accurate physiological signals and reduce the interference of human body movement on the signal, the conductive hydrogel mat...
