Abstract

The invention relates to the technical field of electroencephalogram, in particular to an electroencephalogram signal acquisition device. The device is used for electroencephalogram signal acquisition and comprises an electroencephalogram acquisition module, an action module and a signal processing module; the electroencephalogram acquisition module is selectively attached to the forehead part and is used for acquiring electroencephalogram signals of the forehead part; the action module is selectively attached to the rear part of the head and is used for acquiring electroencephalogram signals of the rear part of the head; and the signal processing module is respectively connected with the electroencephalogram acquisition module and the action module, and is used for preprocessing and processing the acquired acquiring signals. By arranging a cap body fitting the outline of the head of the human body and integrating the acquisition device, the processing device and a transmission device on the cap body, due to the special structure of the cap body, the mode that in the prior art, a center acquires electroencephalogram signals by pasting electrode slices is replaced, and the problem of wearing comfort of a wearer is solved.

Description

Technical field [0001] The present invention relates to the field of ecpoionics, and in particular, there is a brain wave signal acquisition device. Background technique [0002] There are tens of millions of neurons in the brain, and the brain nerve signal is a biological signal associated with the brain. Each neuron can produce a small electric field, and the brain wave is a collection of small signals. Brain wave usually describes the frequency domain, affected by external stimulation and inherent mental state, the frequency domain of brain waves, and the amplitude change. Among them, Delta, Theta, Alpha, Beta and Gamma Wave are the name of different frequency brain waves, which describes the state of many brains. [0003] Based on the above mechanism, the original EMG signal is collected by the dry electrode EMG sensor, and the signal is converted from the time domain to the frequency domain by signal processing technology, then Delta, Theta, Alpha, Beta and Gamma 5 kinds of ...
