Wearable bio-electricity signal collection device

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...

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 advantage is that it is easy to wear and take out, but it has the following disadvantages: (1) It cannot meet different head shapes because it does not have enough elasticity. (2) Due to the irregular outline of the human body, the rigid support structure itself does not fit well with the skin, so the electrodes and the skin are also prone to poor contact, which is more obvious when the number of electrodes is large; (3) This rigid support structure is only limited to 3-5 conductive electrodes, which is far from meeting the needs of medical, psychological cognition and other applications
