A kind of wearable acquiring biological electric signals helmetTechnical field
The present invention relates to a kind of wearable acquiring biological electric signals helmets, belong to bioelectrical signals detection, transmission technologyField is particularly suitable for EEG signals record.
Background technology
Common bioelectrical signals mainly have electrocardio, brain electricity, myoelectricity etc., these body surface bioelectrical signals can usually pass through electricityPole records, and amplifies through bioelectric amplifier appropriate, record and become electrocardiogram, electroencephalogram, electromyogram etc..Brain electricity（EEG）It isA kind of common bioelectrical signals, it is obtained big using the variation of the neuropotential pattern measurement brain electrical signals of brain activityBrain function information, advantage are temporal resolution height.EEG can be divided mainly into two kinds of intrusive EEG and non-intrusion type EEG.It invadesAlthough it is high to enter formula EEG spatial resolutions, there is damage to subject, it is difficult to practical.Therefore non-intrusion type EEG is at present using mostIt is extensive.With the fast development of the emerging technologies such as big data, cloud computing, portable medical, expedites the emergence of and be based on real life scenariosBrain electricity application.The application of real life scenarios brain electricity does not require nothing more than that signal is reliable, and more focuses on the convenience used and relaxAdaptive.
The prior art mainly uses wet electrode technology, that is, needs to use conductive paste（Glue）Electrode technology.Although wet electrodeSignal stabilization is reliable, but conducting resinl and skin need to be used to pre-process, and complicated to take, subject feels uncomfortable.Conducting resinl can be made dirtyThe hair of subject needs to wash hair after record.Therefore, wet electrode is difficult to apply to the eeg recording of real life scenarios.In order to gramWet electrode inconvenience, uncomfortable problem are taken, has developed dry electrode technology in recent years.Dry electrode refers to any completely without usingAdditional electrolyte, electronic conductor directly with the electrode technology of skin contact.Therefore dry electrode installation is quick, easy to use, but byIn unstable with skin contact, signal quality is poor.Electrode supporting structure is most important, it directly affects electrode and skin contactStability.Development Energy and comfort and the electrode supporting structure that can stablize with skin contact be the key that break through dry electrode technology itOne.
Prior art electrode support construction is broadly divided into elastic support structure, two class of rigidity supporting structure.Resilient support knotStructure main representative is the electrode cap made of elastic fabric, and major advantage has elasticity, same electrode cap preferable with skin attachementThe different subject wears of multiple head dummys can be met to require, disadvantage can not exactly ensure electrode uniform force, not with skin contactStablize, impedance is unstable.The main representative of rigidity supporting structure is headband or the helmet made of duroplasts or hard silica gel, mainlyAdvantage is to wear, pick and place conveniently, but having the following disadvantages：（1）Due to not having elasticity, cannot meet multiple and different head dummys byThe wearing requirement of examination person；（2）Since human head profile is irregular, rigidity supporting structure itself is bad with skin attachement, thereforeElectrode is also susceptible to skin to be contacted bad, and electrode number is more to be become apparent；（3）This rigidity supporting structure is confined to3-5 conductive electrodes far can not meet the needs of the applications such as medical treatment, psychological cognition.
