In recent years,muscle nerve diseases have seriously harmed people's health.Therefore,people need a long-term continuous and stable electromyography monitoring electrode to monitor people's health status in real time,so as to find muscle abnormalities earlier for treatment,and reduce the damage of muscle nerve diseases to people's living quality and life.At present,there are many kinds of EMG monitoring electrodes.Firstly,we briefly review the electrode types and working principles of EMG monitoring,and compare the characteristics of various electrodes and monitoring methods.It is found that the non-invasive fabric dry electrode can be healthy and comfortable for long-term EMG monitoring,which is the focus of long-term continuous stability of the EMG monitoring electrode.The development status of fabric dry electrodes for long continuous stable EMG monitoring is summarized in terms of three aspects:electrode structure and preparation technology,property characterization and evaluation technology and EMG monitoring suit integration technology.We introduce the influence of material,structure and preparation technology on the properties of fabric dry electrodes in the section on structure and preparation technology.In the section of performance characterization and evaluation techniques,we summarize both the impedance and surface EMG characterization and compare the methods,and characteristics of the surface EMG signal noise reduction with those of the skin-electrode contact impedance measurement method.In the section of EMG monitoring suit integration technolog,we analyze the methods and characteristics of integrating conductive materials,conductive yarns and finished fabric dry electrodes with clothing.The existing research results show that although the existing fabric dry electrodes cannot meet the long-term continuous and stable EMG monitoring performance requirements,some progress has been made in the structure and preparation technology of fabric dry electrodes,electrode performance characterization and evaluation technology and electrode integration technology.First,conductive materials(containing oxygen and nitrogen elements)that can form hydrogen bonds with fabrics(containing oxygen and nitrogen elements)and chemical(liquid),electrochemical and vapor deposition processes that can prepare thin and uniform conductive layers on uneven fabric surfaces are suitable for the preparation of dry electrodes for long-term continuous and stable EMG monitoring fabrics.However,in order to better perform long-term continuous EMG monitoring,it is still necessary to pay attention to the effects of friction,bending and perspiration corrosion on the stability of dry electrode signal monitoring of fabrics.Second,when the fabric dry electrode is integrated with clothing,the modification of the fabric dry electrode by introducing soft materials can increase the adhesion performance of the fabric dry electrode to the skin,which is conducive to improving the signal stability of the fabric dry electrode during long-term continuous dynamic EMG monitoring.Generally,during long-term dynamic EMG monitoring,the fabric dry electrode will have unstable monitoring signals due to bending,friction and perspiration,and the unstable signal affects the identification and application of EMG,so improving the strain stability and perspiration corrosion resistance of fabric dry electrodes is the current technology that needs to be broken through.
