Problems solved by technology

However, in the existing reports, the following problems have not been effectively solved: (1) Washability, rubbing resistance, and stretchability. Whether it is medical monitoring or sports monitoring, wearable electrodes need to be able to be cleaned repeatedly And effectively maintain its characteristics; and the electrode will inevitably be pulled when placed on the clothing, requiring the electrode to have good elasticity and shrinkage, and to effectively maintain the original conductive characteristics after stretching and rebounding; (2) Long-term Time stabilit...

Abstract

The invention provides a flexible wearable dry electrode and a preparation method thereof. The flexible wearable dry electrode comprises a basic cloth material, a transfer print gelatinous layer and a nanometer electric conduction layer which are sequentially attached. The transfer print gelatinous layer is prepared from, by weight, 50-90% of elastic resin, 5-15% of curing agent and 5-35% of filler. The nanometer electric conduction layer is prepared from, by weight, 0.1-20 parts of electric conduction nanometer materials, 0.1-30 parts of dispersing agent and 0.01-5 parts of adhesives. The preparation method includes the steps of preparing electric conduction coating liquid and transfer print gelatine, sequentially arranging the electric conduction coating liquid and the transfer print gelatine on a flexible release film through transfer print, pressing the flexible release film on the basic cloth material, conducting resolidification, and tearing off the release film. The flexible wearable dry electrode has the advantages of high conductivity, high flexibility, high environment tolerance, long-time stability, washing resistance, kneading resistance and the like, can be freely cut according to garment requirements, and is high in universality.

Description

technical field [0001] The invention relates to the field of flexible electrode materials, in particular to a flexible wearable dry electrode and a preparation method thereof. Background technique [0002] With social progress and economic development, the mobility and intelligence of medical equipment has become an irreversible trend, especially the intelligence, mobility, and home use of ECG, EEG, and EMG equipment that are closely related to human health. change. However, whether it is the ECG electrodes, EEG electrodes, and EMG electrodes widely used in clinical medicine, or the conductive rubber used in the heart rate belts worn by ordinary people during exercise, there are many insurmountable problems. [0003] For example, most of the ECG electrodes used in clinical practice are disposable Ag / AgCl electrodes with conductive paste. Although such electrodes can provide medical personnel with short-term and reliable ECG signals, they are discarded after one use. At the...
