Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, body surface electric conductance distribution detector of the present utility model is described in detail, in accompanying drawing, parts same as the prior art have adopted identical label.Following each embodiment is only not limitation of the utility model for this utility model is described.
Fig. 1 is the internal structure block diagram of body surface electric conductance distribution detector of the present utility model; Fig. 2 is body surface electric conductance distribution detector surface structure schematic diagram of the present utility model.As depicted in figs. 1 and 2, body surface electric conductance distribution detector of the present utility model, comprises and is arranged on tester shell 11 array electric derivative sensor 1, path change-over switch 2, electric charge detector 3, multichannel ADC transducer 4 and data processor 5 inner and that connect successively.Path change-over switch 2, electric charge detector 3, multichannel ADC transducer 4 and data processor 5 are connected with embedded signal processor 7 respectively, are also connected with display 6 on embedded signal processor 7.One side of tester shell 11 is distributed with multiple test electrodes 13, and is provided with one deck dielectric film 12, and test electrode 13 is connected with the array electric derivative sensor 1 that is arranged on tester shell 11 inside.The opposite side that tester shell 11 is relative with a side that is provided with test electrode 13 is provided with display screen, and display screen is connected with the display 6 of tester enclosure.
It is flat rectangular-shaped that tester shell 11 is, and test electrode 13 and display screen are arranged at respectively the front and back of tester shell.The left side of tester shell 11 and right side are connected with respectively a fixing band, and left fixing band 9 is connected to the left side of tester shell by fixing band connecting axle 10, and right fixing band 14 is connected to the right side of tester shell by fixing band connecting axle 10.On right fixing band 14, be socketed with retainer ring 15, the end of right fixing band 14 is provided with fixed agraffe 8.When use, left fixing band 9 passes fixed agraffe 8 and is fixed according to tightness, and the redundance that left fixing band 9 stretches out fixed agraffe 8 fetters fixing by retainer ring 15.
Theoretical basis of the present utility model is as follows: any biology is all by molecular composition, and molecule is by atomic building, and atom is made up of atomic nucleus and electronics.Electronics produces magnetic field around atomic nucleus rotation.The psychology of human body, when physiology changes, is first that the structure of matter key element that forms human body changes, and the proper motion of the electronics of constituting atom is first abnormal.Due to the dependency in electron motion and magnetic field, once cause that the resonant field of normal electronics changes, from atom to molecule, from molecule to cell, the information transmission channels from cell to organ changes, and result causes the variation that body internal electric field distributes.
In fact, in the time of measured's anxious state of mind, skin resistance value is not dull decline, but fluctuation up and down sharp.In the time of anxious state of mind, the dissipative structure of electromagnetic field there will be significantly fluctuation, thereby causes fluctuating widely of health electric conductance ability.
Electric conductance (J) is the inverse of resistance (R), namely R=1/J or J=I/V).From physical angle, electric conductance (J) is directly proportional to electric field intensity.J=σ E, σ is a constant relevant with material.What on skin, measure is not what skin resistance but health electric conductance, according to formula J=σ E: electric conductance (J) is to be directly proportional to electric field intensity (E).Conclusion is that what on skin, to measure is exactly the electric field intensity (E) in health.
" dissipative structure " is a kind of dynamic structure, relies on continuous energy supply to exist, and Energy distribution in human body is the dissipative structure being formed by electromagnetic wave.The organ of human body, tissue, cell, molecule etc. all can emitting electromagnetic wave, so they are all electromagnetic wave sources, claims again " oscillator ".The heart of human body and lung are exactly two typical electromagnetic wave sources, are also two oscillators.Conventional electrocardiogram is exactly to measure the electromagnetic wave that heart sends.The lung electrograph being of little use is equally also to measure electromagnetic wave.They must have natural frequency separately, but they again can not be completely independent.When motion, all want each other corresponding acceleration; When rest, corresponding deceleration again.
Physics theory points out, the electric conductance of human body is directly proportional to the intensity of internal electric field.To a great extent, the measurement of human body electric conductance can move at body surface, thereby measures the distribution of human body internal electric field.The non-uniform Distribution of this internal electric field is mainly by the overlapping generation of standing electromagnetic wave.We there is no need the electromagnetic frequency spectrum of measurements and calculations, and can carry out sampling determination to this electromagnetic interferogram at body surface, thereby draw the change of human physiology and psychology state.
For by the electric field intensity in body surface detection body, do not affect again the electric field of human body itself.Between detecting electrode and skin, place dielectric film, made to have formed one between detecting electrode and skin and measure capacitor C s.By the detection to electric capacity, extrapolate the electric field of body surface.
Fig. 3 is the circuit theory diagrams of electric charge detector of the present invention.As shown in Figure 3, electric charge detector inside is provided with operational amplifier 19, and integrating capacitor 18 is connected between the in-phase input end and outfan of operational amplifier 19, reset switch K 2in parallel with integrating capacitor 18.Between body surface potential 16 on detecting electrode and skin, form and measure capacitor C s, measure capacitor C s and pass through K switch 1be connected to the in-phase input end of operational amplifier.When measurement, first, to measuring capacitor C s charging, Closing Switch K 1, record measuring voltage V from the voltage measurement point 17 of the inverting input of operational amplifier 1, then cut-off switch K 1, obtain measuring charge Q from the outfan 20 of operational amplifier 1; Then, allow and measure capacitor C s electric discharge, Closing Switch K 1, obtain bias voltage V from voltage measurement point 17 2, then cut-off switch K 1, obtain biascharge Q from the outfan 20 of operational amplifier 2.According to formula C s=(Q 1-Q 2)/(V 1-V 2), can obtain the capacitance between detecting electrode and skin, thereby extrapolate the electric conductance of body surface.
Record body surface each point by array conductivity sensor and obtain after current potential, calculate capacitance Cs through A/D converter, calculate the intensity of human body internal electric field.Obtain body surface electric conductance scattergram by data processor and embedded signal processor, and show on display.
This technology only detects by external electrode and electrode and skin insulate, and on subjects, without any impact, accuracy of detection is high, and detection speed is fast, good stability.For psychologic biofeedback provides a kind of new feedback technique.By calculating and the graph technology of computer, just can obtain the scattergram of human body surface electric conductance.It can reflect human body psychology and physiological variation, can be psychologic biofeedback a new feedback quantity is provided.
Body surface electric conductance distribution detector of the present utility model, the skin Electric Measurement Technology that psychological field is generally used, improves.The alternative skin Electric Measurement Technology of conductance measurement technology, more reasonable, more scientific than existing skin electrical measurement method.Can be applicable to the emotion changes of test person, attention change, the psychological fields such as state of consciousness variation.
