Aiming at some problems in long-term electrocardiogram（ ECG） monitoring using traditional Ag / Ag Cl gelled electrodes

and urgent need in wearable health monitoring in recent years

a review of new type of sensor technology named textile electrode technology applied for ECG signal acquisition is presented. Concept of dry electrodes and textile electrodes are introduced; research progress of textile electrode technologies is analyzed from two aspects of active electrode and inactive electrode separately; some technologies such as manufacture craft

conductor material

carrier

and electrochemistry performance are discussed; restraining factor of textile electrode in market application is analyzed

and development direction is prospected.
