Example Embodiment

Example 1:

As shown in Figures 1, 2 and 3, a concentric metal body surface electrode includes a lead buckle and an electrode sheet. The electrode sheet is a concentric double electrode structure composed of a metal ring 1 and a metal disc 2 , The inner diameter of the metal ring is larger than the outer diameter of the metal disc. One side of the metal ring 1 and the metal disc 2 is a rough microstructure (as shown in the shaded part in Figure 1 and Figure 3), and the other side is a smooth structure , The wire ties 3 are respectively arranged on the smooth structure surface of the metal ring 1 and the metal disc 2. The metal ring 1 and the metal disc 2 are integrally connected to form a concentric double electrode structure.

The preparation method includes the following steps:

The first step is mechanical cutting. Choose T2 copper as electrode material, use wire cutting method to produce metal ring material 1 with outer diameter of 60mm and inner diameter of 40mm and metal ...

Abstract

The invention discloses a concentric circle type metal body surface electrode for a bioelectrical impedance detection technology and a manufacturing method thereof. The method comprises the following steps of: manufacturing metal ring and wafer materials of different sizes by using a mechanical cutting method, and then cleaning the surfaces of the materials to remove dirt on the surfaces; preparing acidic copper chloride etching solution consisting of hydrochloric acid, sodium chloride and copper chloride, and forming a series of micro structures on the surface of the metal ring by using an etching processing method to enlarge the surface area of the electrode; and after the etched metal ring and the wafer are cleaned and dried, integrally connecting the metal ring and the wafer by using non-woven fabric or foam with viscosity to form a concentric circle type double-electrode structure, welding lead buckles and finally obtaining excitation and measurement electrode integrated concentric circle type metal body surface electrode. The method has simple manufacturing process, high production efficiency and low cost, and can effectively reduce the contact impedance of the metal body surface electrode and the human skin and improve the measurement precision of the bioelectrical impedance detection technology.

Description

A concentric metal body surface electrode for bioelectrical impedance detection technology and its manufacturing method technical field The invention relates to a biomedical electrode, in particular to a concentric metal body surface electrode for bioelectrical impedance detection technology and a manufacturing method thereof. Background technique Bioelectrical impedance detection technology is a detection technology that uses the electrical characteristics and changing laws of biological tissues and organs to extract biomedical information related to human physiological and pathological conditions. The implementation of this technology usually needs to send a small AC measurement current or voltage to the detection object with the help of an electrode system placed on the body surface, and detect the electrical impedance and its change of the corresponding part, and finally obtain relevant information according to different application purposes. Physiological and patholog...
