Description

technical field [0001] The invention relates to the technical fields of textiles and electronics, in particular to a flexible defibrillation electrode based on a three-dimensional fabric structure and a preparation method thereof. Background technique [0002] In view of the current related technologies, the structure of the defibrillation electrodes that can be applied to medical equipment is mainly a rigid plate-like structure, and the preparation of the material system is generally realized by combining metal plates with conductive coatings. Defibrillation electrodes of this type often need to be covered with biocompatible viscous materials, such as electrolyte hydrogels, before use. Prepare for defibrillation by attaching electrodes covered with adhesive material to the skin.

AI Technical Summary

Problems solved by technology

This type of defibrillation electrode has problems such as complex and cumbersome processing, and the conductive coating of the defibrillation electrode is easy to fall off after long-term use.

In the context of the rapid development of portable medical emergency equipment, defibrillation electrodes with rigid plate structures still have problems such as poor moisture permeability and poor skin-adherence, and it is difficult to meet the needs of patients who wear them for a long time, making this type of defibrillation electrodes The application scenarios are relatively limited

[0003] In addition, judging from the existing technologies related to fabric flexible electrodes, flexible electrodes based on fabric structures are mostly used in the collection of bioelectrical signals, and there are relatively few technical researches on cardiac defibrillation.
