Referring to fig. 5, fig. 5 is a schematic structural diagram of an optical fiber macrobend sensor, which includes a light source 20, a photodetector 21, a flexible optical waveguide 22, a connector 23, and a wire 24. Wherein, the light source 20 and the photodetector 21 are respectively fixed at two ends of the flexible optical waveguide through connectors 23. The flexible optical waveguide 22 is wrapped in the flexible colloid 25 and forms a regular cylinder with the flexible colloid 25. The light source 20 and the photodetector 21 are also connected to an external circuit through wires 24, respectively.
In one embodiment, the flexible optical waveguide 22 is a regular cylinder with flexible properties, and the flexible optical waveguide 22 has a certain transmittance for the light emitted from the light source; the light source is monochromatic light or non-monochromatic light. The soft gel 25 is a non-rigid material and has the characteristics of being capable of being stretched, contracted and bent at will. Preferably, the bending diameter of the flexible optical waveguide is more than 1.2cm, and the diameter of the flexible optical waveguide is more than or equal to 10% of the diameter of the soft colloid.
In one embodiment, the light source 20 is a low power LED with a center wavelength of 750nm or 1250nm, a half-value width of 150 nm; the responsivity of the photoelectric detector 21 is 0.3A/W, and when the central wavelength of the light source is 750nm, the detection range of the photoelectric detector is 610nm-780 nm; when the central wavelength of the light source is 1250nm, the detection range of the photoelectric detector is 1110nm-1578 nm; by arranging the light source and the photoelectric detector in this way, the power consumption of the optical fiber macrobend sensing device is low, the detection precision is high, and the application on the pillow is facilitated.
In one embodiment, the photodetector 21 may be any photoelectric element that can convert an optical signal into an electrical signal. The optical signal detected by the photoelectric detector is light intensity, polarization, wavelength, phase and frequency.
Specifically, light emitted by the light source enters the photoelectric detector after passing through the flexible optical waveguide, and the photoelectric detector converts an optical signal into an electrical signal. When the flexible optical waveguide deforms along with the soft colloid, part or all of parameters of the light inside the flexible optical waveguide change; wherein the parameters of the light include light intensity, polarization, wavelength, phase, and frequency. The flexible colloid plays a role in protecting the flexible optical waveguide, when the flexible optical waveguide deforms, the incident angle of light inside the flexible optical waveguide at the interface between the flexible optical waveguide and the air is reduced, so that the light intensity lost in the transmitted air is increased, and the light intensity detected by the photoelectric detector in the reflected flexible optical waveguide is reduced.
When the macrobend sensor of optic fibre is pressed close to human neck, human breathing and heartbeat activity can produce certain external disturbance (define external disturbance volume and be triangle E), transmit to the macrobend sensor of optic fibre through the neck artery, and the power of correspondingly applying the macrobend sensor of optic fibre can make optic fibre deformation change, then:
wherein, Δ E is the external disturbance amount, Δ T is the corresponding variation of the optical fiber transmission constant, D is a constant related to the external disturbance amount Δ E, where D Δ E is Δ X, and Δ X is the corresponding deformation amount of the optical fiber. From the relationship of force to deformation, one can obtain:

When the body movement phenomena such as dreaming or turning over occur in the sleeping process, the monitoring circuit can also monitor the breathing abnormality, but the frequency of the abnormality occurrence is more discrete, so that in this case, the control and processing circuit can also control the air bag adjusting circuit to adjust the air bag, so that the head of the sleeper is in a better sleeping posture.
In some embodiments, the intelligent pillow further comprises a sound sensor, and whether snoring occurs or not can be accurately judged and automatically adjusted through the sound sensor and the optical fiber macro-bending sensor, so that the phenomenon that snoring affects sleeping quality or affects rest of other people is avoided. Specifically, when the sound sensor monitors that sound occurs, whether breathing is abnormal is judged through breathing data monitored by the optical fiber macro-bending sensor, if breathing is not abnormal, the sound may come from external interference instead of snoring; if breathing is abnormal, the snoring phenomenon is judged, and the control and processing circuit starts the air bag adjusting circuit to adjust the air bag until the breathing data is normal. In general, when a snorer snores, the snorer can stop snoring only by slightly adjusting the head posture.
In some embodiments, the intelligent pillow further comprises a power supply for supplying power to the light source and the PCB. The power supply is a dry battery, and the light source is a low-power-consumption LED and has low power, so that the power supply requirement of the light source is met by supplying power through the dry battery, the safety performance of the product is improved, and the safety problem caused by adopting other power supplies such as a lithium battery is avoided.
The intelligent pillow has the advantages of high sensitivity, accurate test precision, capability of reaching a medical grade, capability of accurately monitoring the respiratory characteristic data of a human body in a sleeping state, wide application range and scene, high product consistency and yield, low cost and convenience for large-area distributed monitoring application.
