Bio-electricity signal acquisition device

Abstract

The application discloses a bio-electricity signal collecting device. The device comprises a collector and a base, and the collector comprises an electrode contact; and the base comprises a base body and a plurality of flexible electrode grippers installed on the base body, the electrode contacts are installed on the outer surfaces of the tail ends of the flexible electrode grippers, a conductive structure is further installed on the base body, and the electrode contacts are connected with the conductive structure through wires installed inside the flexible electrode grippers, so that the collector transmits the bio-electricity signal collected by the electrode contact through the conductive structure. Through the arrangement of the flexible electrode grippers, the use experience of a user in the process of making contact with the scalp is improved, the comfort in the wearing process is improved, so that the electrode contacts can be tightly attached to the scalp; and the conductive plating layers covering the electrode contacts provide small resistance and contact impedance, so that the purpose of acquiring the electroencephalogram signals for a long time is achieved.

Description

technical field [0001] The present application relates to the technical field of bioelectrical signal collection, in particular to a bioelectrical signal collection device. Background technique [0002] Bioelectricity is the most basic physiological phenomenon of living organisms. By monitoring bioelectrical signals, various physiological diseases (such as cerebral thrombosis, myocardial infarction, arrhythmia, cardiac arrest and other cardiovascular and cerebrovascular diseases) can be diagnosed and prevented. In addition, bioelectrical signals can also be used in research in the fields of brain-computer interface, rehabilitation medicine, and sleep monitoring. At present, bioelectricity detection electrodes are mainly used to contact the human body to collect various biopotentials. The related bioelectric detection electrodes have the following problems: 1. Wet electrodes usually need to be used in conjunction with conductive gel and adhesive, and the gel or adhesive will...

AI Technical Summary

Problems solved by technology

The related bioelectric detection electrodes have the following problems: 1. Wet electrodes usually need to be used in conjunction with conductive gel and adhesive, and the gel or adhesive will irritate the skin, and the performance of the electrode will deteriorate as the gel dries up. Rapid decline, it is difficult to use for long-term monitoring of bioelectrical signals; 2. The motion artifact of the hard dry electrode (that is, the noise generated when the skin and the electrode are relatively displaced) is relatively large, and it is usually necessary to use microneedles or finger structures to increase The contact area between the electrode and the skin is to reduce the contact impedance, so there are symptoms such as skin damage caused by skin infection, and long-term wearing will also increase the discomfort of the user; 3. Semi-dry electrodes need to be used in combination with conductive liquid, which cannot be used for long-term monitoring
