The ECG monitor comprises an ECG monitoring electrode plate, wherein an electrode in the electrode plate is a metal conductor for taking various bioelectricity phenomena in a human body, and the impedance, polarization characteristics, stability and the like of the electrode plate have great influence on the measurement accuracy. The electrodes can be divided into copper alloy silver-plated electrodes, nickel-silver alloy electrodes, zinc-silver-copper alloy electrodes, stainless steel electrodes, silver-silver chloride electrodes and the like according to materials. The existing ECG monitor mostly adopts a disposable suspension electrode, also called button electrode, and has a structure that a silver chloride electrode is fixed on a foam pad, and a foam plastic disc coated with conductive paste is also adsorbed at the bottom. Before use, a layer of protective paper is adhered around the disc, the disc is packaged in a box bag made of metal foil, and the disc is taken out when in use and the protective paper is peeled off for use. However, the silver chloride electrode is a hard electrode, and the hard electrode is not tightly attached to the skin, and unexpected displacement artifact may be caused along with the change of the state, so that the monitoring data of the electrocardiograph monitor is distorted. Moreover, although the disposable electrode is convenient to use, the consumption of electrode materials is large, and huge waste of resources is caused.
