Wearable electroencephalogram collector

Abstract

The invention discloses a wearable electroencephalogram collector. The electroencephalogram collector comprises electroencephalogram electrodes, an electroencephalogram signal processing module, a signal transmitting module and a power module, wherein the electroencephalogram signal processing module is disposed at the front end of an annular body; the electroencephalogram electrodes include a plurality of collecting electrodes, an acting electrode and a grounding electrode; the collecting electrodes, the acting electrode and the grounding electrode are disposed on the inner side of the annular body; the electroencephalogram signal processing module comprises a signal amplifying module, a filter processing module and a digital to analog conversion module; the collecting electrodes, the acting electrode and the grounding electrode are connected to the signal amplifying module of the signal amplifying module; the signal amplifying module, the filter processing module and the digital to analog conversion module are sequentially connected; the digital to analog conversion module is connected with a Bluetooth transmission module connected to a data receiving module. The wearable electroencephalogram collector has the advantages that the three-electrode design is used, the use problems of silver-silver chloride wet electrodes used in traditional electroencephalogram collectors are solved, data can be provided to different fields, and application of the electroencephalogram technology in various fields is expanded greatly.

Description

technical field [0001] The present invention relates to an EEG collector, in particular to a wearable EEG collector. Background technique [0002] In recent years, in the field of aviation and aerospace, EEG acquisition technology has played a good role in the fatigue monitoring of flight personnel. In addition, in the field of archery, muscle and strength are not the primary factors for winning, and being able to ensure good concentration and concentration is the key to winning. In the United States, South Korea and some European countries, professional archery athletes use EEG acquisition technology to train the concentration of the brain, which can help athletes improve their training performance. In addition, EEG acquisition technology has broad development prospects in entertainment, education, health and other fields. Therefore, this technology has become a research hotspot at home and abroad. [0003] EEG acquisition is a system that can establish information inter...

AI Technical Summary

Problems solved by technology

[0007] (1) Silver-silver chloride wet electrodes are needed in the existing EEG acquisition equipment, which is inconvenient to use, and the gel has certain damage to the skin, especially for people with allergic skin;

[0008] (2), the existing wet electrode EEG acquisition equipment is complicated to use and is easily restricted by the environment;

[0009] (3) The data collected by the existing wet electrode EEG is mainly for medical services, and the collected data cannot be used by other industries, thus limiting the use of its EEG technology in other fields, and the practical scope is limited
