Embodiment 1

[0027] Such as Figure 1~3 As shown, a biomedical electrode with surface microstructure array characteristics includes four parts: metal electrode core 1 , foam material backing 2 , conductive silver glue 3 and shielding wire 4 . The metal electrode core 1 is pasted on the other side of the foam material backing 2, such as figure 1 shown. The foam backing material 2 and the shielded wire 4 realize the solderless connection through the conductive silver glue 3, such as figure 2 shown. The surface of the metal electrode core has surface cone-like microstructure array features, such as image 3 shown.

[0028] The manufacturing process method includes the following steps:

[0029] The first step is laser processing. Copper metal flakes are selected as the raw material of the metal electrode core. By designing the laser processing route and using laser micromachining technology, a linear array with a vertical and horizontal spacing of 0.1mm×0.1mm conical surface microstruct...

Embodiment 2

[0036] The raw material of the electrode core in the first step can be selected as a metal aluminum sheet material, and a linear array of columnar microstructures with a vertical and horizontal spacing of 0.2mm×0.2mm can be formed by laser processing. Others are the same as in Example 1.

Embodiment 3

[0038] The raw material of the electrode core in the first step can be selected as a stainless steel sheet material, and a linear array of circular microstructures with a vertical and horizontal spacing of 0.3mm×0.3mm can be formed by laser processing. Others are the same as in Example 1.

Abstract

The invention relates to a biomedical electrode, in particular to a biomedical electrode with a surface micro-structure array and a manufacturing method thereof. The biomedical electrode with the surface micro-structure array characteristic comprises a metal electrode core, a foam materiel back lining and a shielded conductor; the manufacturing method of the biomedical electrode comprises the steps as follows: sheet metal serves as the raw material of the metal electrode core, a laser micro-processing technology is adopted to form a micro-structure array with the longitudinal distance of 0.1-0.3 mm and the transverse distance of 0.1-0.3 mm on the metal electrode core, cleaning and drying are performed, then hydrochloric acid is utilized to remove an oxidizing layer and impurities, alcohol is utilized for cleaning, and a Au or Ag / AgCl thin layer is plated on the surface of the metal electrode core; the metal electrode core is stuck to the surface of the foam materiel back lining by glue; the shielded conductor penetrates through the foam materiel back lining, and is connected to the surface of the metal electrode core with the method of filling conductive silver adhesive, and solderless connection of the metal electrode core with the shielded conductor can be formed after the conductive silver adhesive is solidified, so that the biomedical electrode with the surface micro-structure array is obtained.

Description

technical field [0001] The invention relates to a biomedical electrode, in particular to a biomedical electrode with surface microstructure array characteristics and a manufacturing method thereof. Background technique [0002] Bioelectricity is the most basic physiological phenomenon of organisms, and the measurement of various biopotentials requires the use of biomedical electrodes. In the process of bioelectricity collection and measurement, the electrode system is often located at the forefront of the test system. In clinical practice, it will directly contact the human skin and exchange and transmit related information, becoming one of the core key parts affecting the entire measurement system. A series of events will also occur on the electrode, including useful information, noise, artifacts, contact impedance, polarization voltage, etc., will enter the subsequent circuit to be amplified, transmitted, and participate in signal processing, and in some cases it is useles...
