Description
Technical field
The invention belongs to psychology biofeedback technology field, relate to a kind of Wearable brain electrosleep quality evaluation instrument.
Background technology
Cerebral nerve can produce faint electric field fluctuation when movable, when ten hundreds of neural whiles is movable, electric field will produce metrical fluctuation.From scalp, just can measure this fluctuation, Here it is brain wave.Brain wave has following feature: it is the bioelectrical signals of the spontaneous generation of central nervous system; It is stochastic signal, has non-stationary and non-Gaussian feature; Can reflect neural state and variation.Therefore, gather brain wave, by analyzing physiology and the mental status that can monitor people.
Non-intervention type brain wave acquisition technology more complicated, because the signal collecting is the small-signal of microvolt level, is easy to be subject to the interference of noise, amplify accurately to signal the processing such as filtering.For the electricity that makes to require mental skill reflects physiology and the mental status of human body, also to carry out spectrum analysis to signal.In the world brain wave is pressed to the different classification of the repetition rhythm and pace of moving things of ripple, unified is following four frequency ranges:
α ripple: 8--13Hz, amplitude, in 50 μ V left and right, mainly reflects that people is in lax and the clear-headed state of closing one's eyes.
β ripple: 13--30Hz, amplitude, at 5-20 μ V, mainly reflects that people is in attention and concentrates or nervous state.
θ ripple: 4--8Hz, amplitude, at 10-50 μ V, mainly reflects that people is in gently sleeping under state, when sleepy, when emotion is constrained.
δ ripple: 1--3.5Hz, amplitude mainly reflects the state of people in deep sleep or has serious OBD at 20-200 μ V.
The quality of sleep quality, directly affects people's physiological health and mental health.Whether the δ wave component reflection people of brain electricity the state in deep sleep, whether has high-quality sleep.Only have the assessment of sleep quality being carried out to science, could take measures targetedly, improve sleep quality, improve people's physiological health and mental health.
In the past, brain wave acquisition treatment facility was bulky, and the collection of EEG signals now, processes, and the work such as spectrum analysis can be completed by single-chip, for portable brain electric test equipment provides technical foundation.Brain electrosleep quality assessment arrangement produces thus.
Existing brain electrosleep quality assessment arrangement, audio frequency and video stimulus signal is many to be provided by common computer or audio & video equipment.Volume is large, uses inconvenient.Assessment to Evaluated effect, many according to people's oneself impression or indirectly, simple some physiological parameters, as electric in skin, heart rate etc. reflect.
On the other hand, along with the development of semiconductor technology, computer volume is more and more less, and power consumption is more and more lower.And adopt virtual image technology, can produce miniscope.The development of these technology has promoted the development of Wearable computer.Wearable computer can be made glasses, also can make wrist-watch or be made in clothes.The spectacle computer of selling in the market, has google, and the product of the companies such as Recon, is mainly used in entertainment field, and price is higher, and the supply of goods is few, is not easy to secondary development.
