Adjustable electroencephalogram electrode module

Abstract

The invention discloses an adjustable electroencephalogram electrode module, and relates to the field of brain-computer interfaces, the adjustable electroencephalogram electrode module comprises a dry electrode, an electrode cover, a conductor, a telescopic block, a shell and a knob, one side of the dry electrode is connected with the electrode cover, the electrode cover is fixedly connected with the telescopic block, the conductor is fixed in the telescopic block, the telescopic block is slidably connected with the shell, and the knob is provided with a knob clamping groove and a screw rod. The knob is connected with the shell through the knob clamping groove; and the screw penetrates through the shell and is in threaded connection with the telescopic block. The distance between the electroencephalogram electrode and the scalp can be autonomously adjusted, the wearing adjustment time can be shortened, and the user comfort is improved.

Description

technical field

[0001] The invention relates to the field of brain-computer interface, in particular to an adjustable brain-electricity electrode module. Background technique

[0002] Brain-computer interface research can be traced back to Hans Berger's EEG signal measurement experiment in 1924. This work has made people realize that humans can directly control external devices or environments through brain signals through artificial "interfaces". In 1973, the concept of brain-computer interface was formally proposed and began to be widely accepted by everyone. The current scientific and technological means have enabled people to deepen their understanding of the mechanism of the brain, which will further promote the advancement and practical application of brain-computer interface technology. In addition, the development of brain-computer interface will in turn provide new insights into the traditional research of the brain. a whole new platform. At present, the EEG acqu...
