Method of manufacturing electrode applied to wearable device

Abstract

The invention discloses a method of manufacturing an electrode applied to a wearable device. The method comprises steps: 1) a silver plating cloth is manufactured: the silver plating cloth is obtained by using nylon fiber as a basic material; 2) a thin film or a viscous polymer material is bonded: the thin film or the viscous polymer material is bonded on the silver plating cloth; 3) an elastic layer is composited: the elastic layer is composited on the thin film to obtain an electrode cloth after composition; and 4) cutting and forming are carried out: the electrode cloth is cut according to a needed size, and thus an electrode applied to a wearable device is obtained. Through bonding the thin film on the silver plating cloth, a fiber conductive coil can be cured, sweat can be quickly gathered, loss of textile physical contact point silver is reduced, resistance is reduced, and water washing-resisting performance is improved; and through compositing the elastic layer and the basic cloth, fitting is more comfortable, the overall electrode cloth is protected, and noise generated when friction with the skin can be reduced.

Description

technical field [0001] The invention relates to an electrode manufacturing process, in particular to an electrode manufacturing method applied to wearable devices. Background technique [0002] Metabolism and all activities in the life process generate electricity. External stimuli, heart beating, muscle contraction, eye opening and closing, brain thinking, etc., are all accompanied by the generation and change of bioelectricity. Physiological studies have shown that bioelectricity is not a by-product or accompaniment of organs or organ functional activities, but a key or decisive factor for cells to achieve some important physiological functions, especially the myoelectric signals given by neurons to stimulate muscles to respond, so that muscles The system generates forces on the skeletal system to perform various mechanical actions. [0003] The bioelectrical signals emitted by the human body itself, such as the above-mentioned heartbeat (ECG signal), muscle contraction (...

Problems solved by technology

[0006] With the development of material technology, electrode devices commonly used in wearable devices with self-contained electrodes, such as weaving carbon fibers into a relatively dense mesh structure to form electrodes that contact the human body, but due to the brittle material characteristics of carbon fibers, The electrodes have a short service life and are not washable; or if the conductive material is coated on the polymer material substrate to form an electrode, the most commonly used method is to use chemical silver plating on the fabric, such as the one disclosed in the Chinese patent application number 200910064618.3 The wearable electrocardiogram electrode device and its manufacturing method include the following steps: cutting the clothes according to the pattern of the clothes; using composite fibers as the base material, plating the nano-silver layer on the composite fibers, and setting the prepared electrodes on the corresponding parts of the clothes; position, silver is friendly to the skin and has a bactericidal effect, but the number of washings of this electrode is still quite limited, and the washability is poor, and more importantly, the entire electrode cannot be guaranteed when the body surface changes during exercise Facing the fit of the body, the impedance of the body current circuit is constantly changing, which will cause current stinging or burns. The market urgently needs novel electrodes to meet these requirements
