The contact of skin surface, detects faint electrocardiosignal.The electrode is added the mixing material injection molding of certain proportion Carbon fibe, In by PC
Its plating metal on surface increases electric conductivity.In addition, the electrode on human skin surface's contact surface, be in heavy caliber vertebra platform shape
Thin slice, and have some small standing shapes in flat surface, for increasing the occlusion degree of human body surface and electrode, surveyed to reduce
Measure myoelectricity interference when electrocardiosignal.The dry electrode can be connect by its column spherical structure with electrode button, easily be installed
Onto different circuits, device and equipment.There is a step between spherical mounting post and big plane, electrode can be helped fixed
Position.
One of preferably, the electrode adds a certain proportion of carbon fiber injected plastics material, injection molding using PC.
Further, the mixed proportion of the carbon fiber in the injected plastics material and PC are adjustable, and by adjusting the ratio
Control its electric conductivity and intensity.
Further, the electrode shape includes a plane contacted with human skin, and a step and one are used for
Connect the spherical column of ECG electrode button.
Further, the electrode plane is diameter cone cell thin slice at a gulp, has certain amount on the disk of upper bottom surface
Small convex shape, for increasing the degree of occlusion of the plane with human body surface skin.
Further, patient comfort's property and inhibition muscle are made an uproar when the number and shape of the small convex shape are by using
The ability of acoustic jamming determines.
Further, the electrode has a thin slice cylinder step between spherical mounting post and vertebra table top lower bottom part, can be with
Facilitate electrode installation positioning.
Preferably two, the electrode surface plating metal increases its electric conductivity and improves and believes faint electrocardio
Number acquisition capacity, anti-interference ability.
Further, metal material used by the coat of metal can be preferred, and faint electrocardiosignal is adopted in increase
Collection ability and anti-interference ability.
Direct benefit of the invention is: providing a kind of low cost, manufacturing process is simple, and ECG signal detection is sensitive dry
Electrode.Facilitate and realizes movement, family, precision electrocardiogram detection.
