Electrophysiological signal fabric collection device

Abstract

The invention discloses an electrophysiological signal fabric collection device, and belongs to the technical field of signal collection, aiming at solving the problems of the prior art that the operation is complicated, skin allergy is easy to cause and the like. The electrophysiological signal fabric collection device comprises a matrix, an anti-ski base layer arranged on the inner surface of the matrix and a conductive fabric layer arranged on the inner surface of the anti-skid base layer, wherein the anti-skid base layer at least covers the periphery of the conductive fabric layer; and the conductive fabric layer is in electric connection or signal connection to a controller. According to the electrophysiological signal fabric collection device, the conductive fabric layer is stably and closely contacted with skin, and cannot generate relative sliding, so that the steps of applying conductive paste, adhesive and the like to electrodes one by one can be reduced, preparation time for signal collection can be greatly reduced, a subject has high comfortable feeling, the using cost is low, and body allergy does not need to be worried; and the conductive fabric layer is closely contacted with skin, so that the signal collection has high quality.

Description

technical field [0001] The invention relates to the technical field of signal collection, in particular to a fabric collection device for electrophysiological signals. Background technique [0002] Electromyography (EMG), electrocardiogram (ECG) and electroencephalogram (EEG) are the three major electrical signals of the human body, which play an important role and significance in scientific experiments, disease diagnosis, health monitoring, etc. , high-quality signals need to be collected before analysis, diagnosis and application. [0003] Existing signal collection mostly uses sticky electrodes or suction cup electrodes, which need to be coated with conductive paste (conductive gel) on the metal head of the electrode, and need to be fixed with sticky glue to improve the conductivity of the electrode and the stability of placement. [0004] The disadvantages of this signal acquisition method are: 1. The use of conductive gel and electrode patches can easily cause redness,...

AI Technical Summary

Problems solved by technology

[0004] The disadvantages of this signal acquisition method are: 1. The use of conductive gel and electrode patches can easily cause redness, swelling and allergies on the skin, causing a burden on the user; 2. The use process is cumbersome, especially for ECG, EMG, etc., which need to wear multiple electrodes The work of collecting data is more cumbersome and costly; 3. The conductive gel will dry up and fall off during use, resulting in the hard electrode surface not being able to fit well with the human skin surface, affecting the contact between the electrode and human skin Impedance, resulting in the inability to continuously obtain signal acquisition for a long time
