[0002] Due to the fast pace and high work pressure of modern society, more and more urban people are in a sub-healthy state. Long-distance running helps promote metabolism and improve cardiovascular and cerebrovascular health, so running sports such as marathons are becoming more and more popular. However, long-term sports will cause excessive load on the heart, so a product that can monitor the changes of human body signs in real time and scientifically guide sports has attracted widespread attention in the market. In recent years, a smart clothing that can extract ECG signals has developed rapidly due to its high precision, comfortable body feeling, and huge amount of collected data.

[0003] The electrodes used in existing smart electrocardiograph clothing to extract signals are mostly made of conductive rubber. The electrodes are connected to the clothing mainly through snaps. However, this connection method has poor shock resistance. After repeated use, the part where the copper ring compacts the wire is prone to loosening, resulting in poor contact and interfering with signal collection. Summary of the invention

When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0023] In addition, it should be noted that the terms left, right, up, down, etc. in the embodiments of the present invention are only relative concepts or are based on the normal use state of the product, and should not be considered as restrictive. The implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0024] like Figures 1-2 As shown, the present invention proposes an ECG monitoring electrode 4, including a circuit board 41 and a plurality of conductive rubbers 43, wherein the conductive rubbers 43 are mounted on the circuit board 41, and a plurality of first through holes 42 are opened on the circuit board 41, wherein the first through holes 42 are distributed in a rectangular array corresponding to the positions of the conductive rubbers 43, and the conductive rubbers 43 are thermoplastically formed on the circuit board 41, and the conductive rubbers 43 protrude from the first through holes 42.

[0025] Compared with the prior art, the ECG monitoring electrode in the present invention realizes a non-mechanical elastic connection between the conductive rubber 43 and the circuit board 41 by thermoplastic molding the conductive rubber 43 on the circuit board 41, thereby improving the shock resistance of the ECG electrode. By positioning and installing the conductive rubber 43 in the first through hole opened on the above-mentioned circuit board 41, the conductive rubber 43 is better fixed, thereby achieving the stability of signal collection after repeated use of the ECG monitoring electrode 4.

[0026] Preferably, in this embodiment, the material of the conductive rubber 43 is a mixture of silicone and silver powder, wherein the content of the silver powder is between 5% and 10% of the total. In this way, the resistance value of the conductive rubber 43 can be reduced. Of course, according to actual conditions, the ratio of the content of silicone to silver powder in the conductive rubber 43 can also be other values, which is not limited here.

[0027] Preferably, the top of the conductive rubber 43 is in a truncated cone shape, which can enhance the deformation ability and deformation recovery of the conductive rubber 43. Of course, the top of the conductive rubber 43 can also be in a rectangular parallelepiped, cylindrical, etc., which is not limited here.

[0028] Preferably, the hardness of the conductive rubber 43 is 30-35° Rockwell hardness, so that the conductive rubber 43 has a certain strength under the premise of having the above-mentioned deformation ability. In this embodiment, the circuit board 41 is placed in the mold, and then the conductive rubber 43 fluid is injected into the mold along the first through hole 42 to form. Specifically, a layer of Teflon coating is first applied to the inner side of the mold cavity (not shown in the attached figure), so as to prevent the conductive rubber 43 fluid from adhering to the mold cavity; secondly, before injecting the conductive rubber 43 fluid, the upper mold temperature of the mold is maintained at 200°C and the lower mold temperature is maintained at 180°C, and then the conductive rubber 43 fluid is injected, so that the molding time in the mold is 95s and the molding pressure is 10Mpa. After the conductive rubber 43 is formed, the circuit board 41 is taken out of the mold by high-pressure cold air and then air-cooled. In this way, the conductive rubber 43 is fixedly connected to the circuit board 41.

[0029] Preferably, the combined portion of the conductive rubber 43 and the circuit board 41 can pass through the first through hole 42 and form a terrace on both sides of the circuit board 41 to prevent the conductive rubber 43 from falling off and increase the contact area between the conductive rubber 43 and the circuit board 41.
