Problems solved by technology

In order to solve the problem of wire connection, some EEG devices with wireless transmission have also appeared on the market, but these devices have specific usage scenarios and functions, and are bulky[6]
For example, the multi-claw structure is only suitable for use when standing or sitting, not suitable for use during sleep
Moreover, the number of leads is small and cannot completely cover the entire brain functional area
[0004] In order to overcome the traditional wet-electrode EEG cap’s complicated operation and difficulty in long-term wearable signal acquisition, as well as the shortcomings of the existing dry-type wireless EEG cap with many restrictions and few leads, the present invention proposes a convenient and comfortable wearable cap. all-in-one flexible EEG cap

Embodiment Construction

[0043] The fixed layer is made of silicone, which not only has a fixed effect, but also has a little softness, which improves the comfort of wearing. Especially for the protruding fulcrum on the inside, it is a little elastic, which can better press the EEG electrodes and ensure the full contact between the electrodes and the skin. The hardware box is made of ABS material, and there is a rectangular hole for connecting with the EEG electrode lead interface. The hardware box and the fixed layer are connected and fixed by Velcro.

[0044] For the conductive layer, first print or apply a layer of film on the surface of the cloth base, then print conductive silver paste on the surface, and then print or apply a layer of film after drying, so that the sandwich structure can be washed with water. Conductive silver paste, the main component is 5wt% silver nanowires (Ag NWs), which has good flexibility while satisfying the conductivity. The end of the lead wire interface is made int...

Abstract

The invention belongs to the technical field of electrophysiological signal detection, and particularly relates to an integrated flexible electroencephalogram cap convenient and comfortable to wear. The electroencephalogram cap is of a three-layer structure, the outer layer is a fixed layer, the middle layer is a conductive layer, and the inner layer is an insulation shielding layer; raised fulcrums with holes are arranged on the inner side of the fixed layer, and the positions of the raised fulcrums correspond to the positions of flexible electroencephalogram electrodes; a detachable hardware box is arranged on the outer side and is used for placing a corresponding hardware module; a jaw belt plays a role in tightening and fixing; a flexible electroencephalogram electrode with a hole, a wire and a correspondingly led-out interface are printed on the conductive layer; and holes are formed in the positions, corresponding to the flexible electroencephalogram electrodes, of the insulation shielding layer, and other parts of the insulation shielding layer are insulated and have the shielding function. According to the electroencephalogram cap, the electroencephalogram electrodes and corresponding connecting lines are directly integrated together, good contact, a convenient wearing mode and comfortable wearing experience are achieved, and early-stage work of electroencephalogram monitoring is greatly simplified.

Description

technical field [0001] The invention belongs to the technical field of physiological signal detection, in particular to a convenient and comfortable one-piece flexible EEG cap. Background technique [0002] Electroencephalogram (Electroencephalogram, EEG) signal is a synthesis of potential information generated by the physiological activities of neuron cells on the surface of the cerebral cortex or scalp. machine interface (BCI), fatigue detection and other fields. It is considered to be the main method for detecting epileptic seizures, psychogenic non-epileptic seizures, migraine, encephalopathy and other diseases [2], and it is also an important basis for the diagnosis of sleep disorders. At present, the EEG cap is usually put on first, and then the EEG electrodes are installed, represented by Gold Cup Electrode [3] and Ag / AgCl electrode [4]. When in use, it is necessary to use conductive paste to connect the gold cup electrode and the skin, wait for sufficient contact a...
