Problems solved by technology

The elastic support structure mainly represents the electrode cap made of elastic fabric. The main advantage of this electrode cap is that it is elastic and fits well with the skin. The same electrode cap can meet the wearing requirements of multiple subjects with different head shapes. The disadvantage is that Unable to guarantee that the electrodes are stressed perpendicular to the scalp, the contact with the skin is unstable, and the impedance is unstable
The main representative of the rigid support structure is a headband or helmet made of hard plastic or hard silicone. The main ...

Embodiment 1

[0045] Example 1: is a basic embodiment of the present invention. As shown in the figure, a wearable bioelectrical signal acquisition device is composed of an electrode support assembly S connected to an electrode 3; the electrode support assembly S includes a connecting belt 1 and a fixing piece 2; the middle part of the fixing piece 2 There are electrode installation holes 2.1, and there are card slots 2.2 for fixing the connection belt 1 at the side; there are at least one pair of two card slots 2.2, which are symmetrically distributed on both sides of the electrode installation holes 2.1; the fixing member 2 passes through the The slot 2.2 is fixed at one end or both ends or in the middle of the connecting belt 1; the connecting belt 1 is an elastic flat belt, and the fixing part 2 is a rigid flat block.

Embodiment 2

[0046] Example 2: is a further example. On the basis of Embodiment 1, the connecting belt 1 is an elastic flat belt that can pass through the slot 2.2 at one or both ends, or the entire connecting belt can pass through the slot 2.2, and there is a hole in the middle that can enter the electrode 3. Elastic flat strip for holes 1.1 or through slots 1.2. Such as Figure 1.1 - As shown in -5, the described card slot 2.2 is a flat single-port card slot 2.21; or as Image 6 The shown card slot 2.2 is a dual-port card slot 2.22; the dual-port card slot 2.22 is composed of two adjacent single-port card slots 2.21 juxtaposed. Such as Figure 8 , 9 , 10, the connection between the electrode 3 and the electrode installation hole 2.1 is clamping, and can also be a threaded connection; the clamping is the fixed boss 2.3 on the inner hole side wall of the electrode mounting hole 2.1 end face The bayonet slot 2.31 is meshed with the bayonet 3.1 on the outer circumference of the electro...

Embodiment 3

[0047] Example 3: is a further example. The difference with embodiment 2 is: as Figure 1.1 As shown in -6, the fixing member 2 is a square rigid flat block, each side has a slot 2.2, a total of 2 pairs of 4 symmetrically distributed on both sides of the electrode installation hole 2.1.

Abstract

The invention relates to a wearable bio-electricity signal collection device which is extensively applied to bioelectricity recording, measuring and stimulating, especially applicable to non-gel bio-electricity measurement. The collection device is formed by the connection of electrode support components; electrode support component comprises connecting belts and fixed pieces, wherein electrode mounting holes are formed in the middle of the fixed pieces, troughs for fixing the connecting belts are formed in the sides of the fixed pieces, and at least a pair of troughs in two are symmetrically formed in the two sides of each electrode mounting holes; the fixed pieces are fixed on one ends or two ends or middle parts of the connecting belt through the troughs in the fixed pieces, the connecting belts are elastic flat belts, and the fixed pieces are rigid flat blocks. The collection device provided by the invention has the advantages of being reasonable in structure, high in degree of fitness between the electrode support component and the skin, stable in electrode impedance, high in measurement precision, comfortable to wear, detachable in electrode, convenient to adjust the position and amount of electrodes, and the electrode is in well contact with the skin.

Description

technical field [0001] The invention relates to a wearable bioelectrical signal acquisition device, which is widely used in bioelectrical recording, measurement and stimulation, including medical equipment, mobile equipment, and home health care, psychological cognition, games, brain-computer interface, rehabilitation training, neural Marketing and other equipment, especially suitable for the occasion of measuring bioelectricity using glue-free electrodes or dry electrodes. Background technique [0002] With the development of science and technology, the measurement of bioelectricity (such as EEG, ECG, EMG, etc.) has been widely used in the monitoring and diagnosis of various nervous system diseases and rehabilitation equipment for bioelectrical feedback. EEG measurement is also an important experimental method in cognitive psychology research. In order to obtain accurate weak EEG signals, good contact between the electrodes and the scalp is required, and the electrode impe...
