Description
Technical Field
The utility model relates to a disposable flexible bioelectricity signal sensor belongs to bioelectricity signal detection, transmission technical field, and the wide application is in clinical medical treatment, wearable health monitoring, is particularly suitable for the EEG signal record.
Background
The clinical common bioelectric signals mainly include electrocardio, electroencephalogram, electromyogram and the like, and the bioelectric signals on the body surface can be recorded through electrodes, amplified through a proper bioelectric amplifier and recorded into electrocardiogram, electroencephalogram, electromyogram and the like. Electroencephalogram (EEG) is a common bioelectrical signal, and measures changes in brain electrical signals using nerve potential characteristics of brain activity to obtain brain function information, which has an advantage of high time resolution. EEG can be largely divided into both invasive EEG and non-invasive EEG. The invasive EEG has high spatial resolution, but is not practical because it is harmful to the subject. Therefore, non-invasive EEG is currently most widely used. Non-invasive EEG places the electrode on the scalp surface, there are many kinds of tissues such as cerebrospinal fluid, dura mater, skull, scalp, etc. between electrode and cerebral cortex surface on the scalp, what the electrode records is the synthesis of the nerve electrical activity of about 4cm range of diameter under the electrode. Electrodes are, of course, a key component of brain electrical acquisition.
The conventional electroencephalogram acquisition mainly uses a disc electrode and an electroencephalogram electrode cap, the disc electrode needs to be fixed by conductive paste one by one, the time consumption is complex, and the electrode falling is easy to occur in the recording process. The electrode cap is convenient to wear by fixing the electrode on the cap body. But often require multiple sizes of electrode caps to meet the signal acquisition of different individuals. In recent years, patch electrodes have also been used to acquire electroencephalograms. The existing patch electrode is generally made of non-elastic materials such as Polyacrylamide (PI) and polyethylene terephthalate (PET), and a wire cable is printed in a linear mode, so that a conductive circuit cannot stretch elastically. Because different individuals have different head types, the flexible electrode with the same size cannot meet the recording requirements of different individuals. Therefore, the phenomenon of too loose or too tight fit with the skin is inevitable, so that the contact with the skin is poor or uncomfortable, and the quality of signal acquisition is directly influenced.
With the coming of the intelligent wearing era, wearable devices based on electrocardio, myoelectricity and electroencephalogram gradually move to civilian use, and the electrodes are required to be suitable for signal acquisition of multiple individuals. Therefore, there is a need to develop an electrode that can simultaneously meet the requirements of different individuals (different head circumference size, wrist thickness, etc.), i.e., an elastically contractible bioelectric electrode. In addition, the patch electrodes are not provided with a handheld part, the foam pad is torn off during use to form a bonding protective film, and the foam pad is easily touched by a hand, so that the viscosity of the foam pad is influenced, and the contact stability of the electrodes and the surfaces of electrodes to be detected is reduced.
