Abstract
The invention relates to an integrated PPG (photoplethysmography) and GSR (galvanicskin response) signal sensor structure combining two types of physiological parameter detection. Fingers are the best position for detecting PPG and GSR; and generally, three finger clips or fingerstalls are required, which are worn on three fingers. According to the invention, a PPG sensor and a GSR sensor are integrated in a finger clip or fingerstall which is worn on a finger to realize detection of two signals. The integrated PPG and GSR signal sensor structure simplifies the sensor composition, is convenient to use, reduces influence on people and lowers the cost.
Description
Technical field
The present invention relates to a kind of physiological parameter detecting sensor structure, particularly a kind of integrated PPG and GSR sensor constructions that made up two kinds of physiological parameter detections.
Background technology
In biofeedback, detect a lie inspection and other psychophysiological measurement, often need to detect simultaneously PPG (PhotoPlethysmoGraphy) light volumetric method pulse wave signal and GSR (Galvanicskin response) the galvanic skin response two kind physiological signals relevant with tensity.The PPG signal detects by photoelectric sensor, is made up of luminous tube and photoelectric receiving tube, and luminous tube shines the detection position with certain wavelength light beam, and the capacity of blood vessel variable signal is obtained in transmission or reflex to photoelectric receiving tube.The GSR signal transducer is made up of two electrodes, is placed on the skin, measures the skin conductivity of reflection sweat gland secretion level.Because two kinds of signals can obtain well to detect effect at finger fingertip, therefore finger is the optimum position of detecting, and the pick off employing refers to press from both sides or the mode of fingerstall realizes.The PPG signal transducer is worn on the finger, and the GSR signal transducer is put respectively and is worn on other two fingers.The detection of two kinds of signals need be used three parts, takies three fingers.
Summary of the invention
The object of the present invention is to provide a kind of incorporate PPG and GSR signal detection sensor structure.
The technical scheme that the present invention realizes:
The photoelectric device of PPG pick off and two electrodes of GSR pick off are integrated in a finger folder or the fingerstall, form incorporate PPG and GSR pick off, be worn on the finger, realize the detection of two kinds of signals.
Advantage of the present invention is: use single loading, realize PPG and GSR signal detection on a finger, simplified the pick off composition, made things convenient for use, reduced the influence that detects the people and reduced cost.
Accompanying drawing and explanation
Integrated transmission-type PPG of Fig. 1 and GSR pick off refer to clamping structure.
1. refer to press from both sides loam cake, 2. refer to the folder lower cover, 3.PPG detects light-emitting tube, and 4.PPG detects photoelectric receiving tube, 5.GSR electrode A, 6.GSR electrode B.
Integrated reflective PPG of Fig. 2 and GSR pick off fingerstall structure.
7. fingerstall top, 8. fingerstall bottom, 9.PPG detects light-emitting tube, and 10.PPG detects photoelectric receiving tube, 11.GSR electrode 1,12.GSR electrode 2.
The specific embodiment
Embodiment 1.
Integrated transmission-type PPG and GSR pick off refer to folder, refer to that folder adopts plastics or elastomeric material to manufacture, and is clipped in finger and upward uses.As shown in Figure 1, PPG detects light-emitting tube 3 and is installed in and refers to that folder loam cake 1, PPG detect photoelectric receiving tube 4, two GSR electrodes 5 and 6, is installed in to refer to folder lower cover 2.During use, pick off refers to press from both sides lower cover 2 contact finger fingertip fronts, and pick off refers to press from both sides the loam cake 2 contact finger fingertip back sides, detects GSR signal and transmission PPG signal.
Embodiment 2.
Integrated reflective PPG and GSR pick off fingerstall, fingerstall adopt plastics or elastomeric material to manufacture, and are enclosed within finger and go up use.As shown in Figure 2: fingerstall top 7 usefulness elastomeric materials are manufactured, and play fixation, and fingerstall bottom 8 is installed PPG and detected light-emitting tubes 9, photoelectric receiving tube 10, two GSR electrodes 11 and 12.During use, pick off fingerstall lower member contact finger fingertip front, GSR signal and reflected P PG signal are detected in the 7 contact finger fingertip back sides, pick off fingerstall top.
Claims (3)
1. integrated PPG and GSR signal transducer structure is characterized in that the photoelectric device of PPG pick off and two electrodes of GSR pick off are integrated in the integrated device that can be worn over a finger.
2. integrated PPG as claimed in claim 1 and GSR signal transducer structure is characterized in that having referring to press from both sides or two kinds of ways of realization of fingerstall.
3. integrated PPG as claimed in claim 1 and GSR signal transducer structure is characterized in that the PPG pick off has reflection and transmission dual mode.
