Abstract

The invention relates to the technical field for processing an electrode sensor used for detecting physiological signals and discloses a method for manufacturing a dry skin electrode; the method includes the following steps: A. selecting a metal sheet with certain thickness, cutting the selected metal sheet into blocks and polishing the surface of the blocks of the metal sheet; B. processing the polished metal sheet blocks, and forming a base and an electrode mast array which are positioned on the base, and the electrode mast array is arranged on the base; C. forming an electrode head at the top end of every electrode master in the electrode mast array by processing; D. plating gold or titanium on the surface of the electrode mast array; E. pasting the base of the electrode on an amplifier; F. arranging a layer of electrically conductive silicone rubber which is sheathed and embedded with the electrode mast array between the electrode head and the base. By adopting the invention, the dry skin electrode array can be quickly and effectively produced and used for detecting brain electricity and myoelectricity and other physiological signals to meet research and clinical requirements.

Description

technical field [0001] The invention relates to the technical field of electrode sensor processing for physiological signal detection, in particular to a method for manufacturing skin dry electrodes by using metal materials and electric discharge processing technology. Background technique [0002] Electrophysiological detection is one of the commonly used clinical inspection methods at present. Generally, electrodes are used to absorb various bioelectricity of the human body for detection. The impedance, polarization characteristics, and biological stability of electrodes have a great influence on the accuracy of physiological signal measurement. [0003] At present, most clinical biopotential measurements use skin wet electrodes such as metal disc electrodes, and the contact impedance is reduced by conductive paste or saline contacting the skin between the electrodes and the skin. The disadvantage of skin wet electrodes is that the signal-to-noise ratio of the obtained phy...
