Abstract

The present disclosure relates to a wearable device for collecting EEG signals by using a flexible extensible electrode. The wearable device is characterized in that a flexible extensible electrode isintegrated on the wearable device; the flexible extensible electrode comprising a flexible extensible substrate layer, an electrode body and a wire drawn from the electrode body; the electrode body and the wire are arranged on the flexible extensible substrate layer; the flexible expandable electrode collects the EEG signal of the target object through the electrode main body and transmits the collected EEG signal to the acquisition device through the wire. The wearable device for collecting EEG signals by using the flexible extensible electrode can collect EEG signals of a detected person atany time and anywhere in the movement of the detected person, is convenient and simple to use, is convenient for the detected person to move, and can realize the collection of EEG signals for a longer time.

Description

technical field [0001] The present disclosure relates to the technical field of medical detection, in particular to a wearable device that uses flexible and extendable electrodes to collect electroencephalogram signals. Background technique [0002] EEG signals are generated by action potentials during the activity of brain nerve cells, which can directly reflect the activity state of brain nerves. EEG signals are composed of waveforms of various frequencies and amplitudes. Each part of the brain has different functions, and the activity of nerve cells in each location is also different, resulting in potentials with different amplitudes and frequencies, and different potential signals. The superposition produced EEG waveforms of different rhythms. [0003] EEG signal is a relatively sensitive objective indicator, which can not only be used in the basic theoretical research of brain science, but more importantly, its application in clinical practice, such as in the diagnosis...
