In one embodiment, as shown in FIG. 1, a sleep monitoring pillow includes a pillow 10, a pillowcase 30, and a sleep monitoring device 50, wherein:

The pillow 10 is made of an elastic material that is used to implement the sleep monitoring function of the pillow itself as a pillow to provide support and comfort to the user's pillow. The elastic material of the pillow cotton 10 may be any one of cotton, feather, latex, and the like as needed, and will not be enumerated and limited.

The pillowcase 30 is mated with the pillow 10 to wrap the pillow 10 so that the pillow 10 made of an elastic material is filled in the pillowcase 30.

As shown in FIG. 2, the sleep monitoring device 50 includes a body 510 and a membrane sensing component 530 that is electrically coupled to the body 510. Specifically, the main body 510 is placed in the pillow 10 for monitoring control in the sleep monitoring pillow. The main body 510 extends from the pillow 10 to the upper portion of the pillow 10 to lay the film sensing component 530 on the upper portion of the pillow 10. .

In one embodiment, in the sleep monitoring pillow of Figure 2, the membrane sensing assembly 530 includes a first membrane sensing component 531 and a second membrane sensing component 533 for sensing respiratory vibration and corresponding output The first pulse voltage component, the second film sensing component 533 is configured to sense the pulse vibration and correspondingly output the second pulse voltage signal.

The first film sensing component 531 and the second film sensing component 533 are in close contact with the front surface of the pillowcase 3 so as to be centrally symmetric and at a predetermined distance apart from the pillowcase 30. In a preferred embodiment, the predetermined distance is 10 cm.

The membrane sensing component 530 is sensitive to dynamic stresses for sensing the pressure exerted by the user through respiratory or pulse vibrations. In other words, for the membrane sensing component 530, the pressure exerted by the user will be It is done by the vibration of its breathing or the vibration of the pulse. Any vibration of the breath or vibration of the pulse will trigger the membrane sensing component 530, which will sense a certain vibration, thereby enabling the membrane sensing component 530 to accurately sense the voltage signals associated with the breathing and pulse during sleep.

Further, in order to ensure the accuracy of the perception and the ease of subsequent processing, the first film sensing component 531 and the second film sensing component 533 are respectively set for the sensing of the respiratory vibration and the pulse vibration, thereby respectively outputting the voltage related to the respiratory vibration. Signal and pulse vibration related voltage signals.

The position of the nose, the second film sensing assembly 533 is placed on the pillow 10 for supporting the position of the user's neck to ensure that the vibrations of the breath and pulse are perceived.

The first film sensing component 531 and the second film sensing component 533 are all of the same structure. The pressure sensor, that is, two film sensing assemblies 530 respectively corresponding to respiratory vibration and pulse vibration, therefore, the first film sensing component 531 and the second film sensing component 533 each include an electrode lead, such as the piezoelectric film shown in FIG. 5311 and signal processor.

The piezoelectric film 5311 includes an electrode 53111 which is led out through the electrode lead to enable the piezoelectric film 5311 to be electrically connected to the control circuit board in the main body 510 through the two electrode wires connected to the electrode 53111. The signal processor It is then placed on the control board to electrically connect to the electrode leads through the control board.

That is to say, the piezoelectric signal outputted by the piezoelectric film 5311 for pressure sensing will be output from the electrode lead to the control circuit board, and the signal processor on the control circuit board will receive the piezoelectric film through the electrical signal connection with the electrode lead. The piezoelectric signal output by the 5311, which in turn processes the piezoelectric signal, processes the pressure sensed by the piezoelectric film 5311 and outputs a corresponding piezoelectric signal to the body 510.

Specifically, the signal processor includes a linear charge amplifying circuit, a low pass filter, a voltage amplifying circuit, and an A/D converter, and the number of low pass filters is two, wherein:

The linear charge amplifying circuit is connected to the electrode wire electrical signal through the control circuit board, and starts with a linear charge amplifying circuit, and connects the sequential electrical signal to a low pass filter, a voltage amplifying circuit, another low pass filter, and The A/D converter, the final A/D converter will be electrically coupled to the body 510 on the control board.

It should be noted that the piezoelectric film 5311 is matched by the signal processor, so that the piezoelectric signal finally outputted to the main body 510 can avoid interference as much as possible, further ensuring the accuracy of the main body 510 to generate sleep data.

In one embodiment, the piezoelectric film 5311 is a monitoring film mainly composed of a polyvinylidene fluoride (PVDF) novel polymer composite piezoelectric material, as shown in FIG. 3, specifically, the PVDF film 53113 will be As the piezoelectric film main body, the piezoelectric film 5311 includes a PVDF material 53112, a PVDF film 53113, an insulating film 53115, a polyester film 53117, and an electrode 53311 plated on the polyester film 53117.

A PVDF material 53112 for pressure sensing is protruded from the PVDF film 53113, and a polyester film 53117 is adhered to both upper and lower surfaces of the insulating film 53115, and an electrode 53111 is plated on the polyester film 53117. In the piezoelectric film 5311, the periphery of the PVDF film 53113 is surrounded by the insulating film 53115, and the polyester film 53117 adhered to the upper and lower surfaces of the insulating film 53115 is The upper and lower surfaces of the PVDF material 53112 are provided with an electrode 53111, and a good electrical contact between the two electrodes 53111 is ensured.

During use, the user is pillowed on the sleep monitoring pillow as described above, and the piezoelectric film 5311 will be subjected to pressure to release electrons to the periphery. In the area direction of the PVDF film 53113, the charge will enter the voltage amplifying circuit through the charge amplifying circuit and A. The /d converter, in turn, can calculate the current applied pressure by reading the output voltage.

Based on this, in the absence of an electric field, the corresponding piezoelectric equation is:

D=d·σ

Where D is the magnitude and direction of the pressure, d is the matrix of piezoelectric stress constants, and σ is the magnitude of the charge in the direction of the area of the PVDF membrane. There is a capacitor in the charge amplifying circuit, the capacitance value is C, and the read voltage value is U, then the relationship between the voltage value U and the charge Q is:

Q=U/C

and

σ=Q/(A·K)

Where A is the area size of the PVDF film 53113, and K is the sensitivity constant coefficient, so that the relationship between pressure and voltage is obtained.

D=d·U/(A·K·C)

It can be seen that the magnitude of the pressure is proportional to the measured voltage value.

That is, according to the pressure principle of the piezoelectric film 5311 as described above, the current stress condition can be estimated from the known area size of the PVDF film 53113 and the monitored voltage value.

In one embodiment, the body 510 of the sleep monitoring device 50 is placed in the center of the pillow 10 to ensure that the rigid body 510 is completely wrapped by the pillow 10 without affecting the user's sleep.

In a preferred embodiment, the battery is a lithium battery and the body 510 further includes a charging interface disposed on the pillowcase 30 for charging the lithium battery.

For the piezoelectric signal processing performed by the microprocessor 513, according to the characteristics of the human body pulse vibration and the respiratory vibration, the pulse vibration is an instantaneous vibration, and the respiratory vibration is a gentle vibration, so the voltage signal outputted by the pulse frequency should be a tip pulse. The voltage signal, while the voltage signal monitoring the respiratory frequency output should be a voltage signal that approximates a sinusoidal shape.

Therefore, correspondingly, the low-pass filter corresponding to the first film sensing component 531 is a sinusoidal pulse type filter circuit, and the low-pass filter corresponding to the second film sensing component 533 is a tip pulse type filter circuit.

Through the sinusoidal pulse type filter circuit, the pulse signal of the tip is filtered, and only the gentle pulse signal is retained; through the tip pulse type filter circuit, the gentle pulse signal is filtered out, and only the lower tip pulse signal is retained.

The microprocessor 513 calculates the frequency of the pulse by detecting the time between two adjacent tip pulse signals in the voltage signal, and calculates the frequency of the breath by the period corresponding to the sinusoidal voltage signal. When the user turns over, the first film sensing component 531 and the second film sensing component 533 will simultaneously detect a sudden large vibration, and therefore, the microprocessor 513 simultaneously monitors through the first film sensing component 531 and the second film sensing component 533. The vibration that comes to the user to know the turning action of the user.

Based on this, the microprocessor 513 continuously generates sleep data by continuously processing the output voltage signal, and sends it to the remote end via the wireless communication module 515.
