[0031] Based on this, the present application provides a flexible detection device applied to glasses, the flexible detection device is arranged in the glasses holder, and the flexible detection device includes: multiple photoelectric sensors, multiple photoelectric sensors are arranged at least in the side area of ​​the nose, and the photoelectric sensors are used to receive the echo signal returned after the nose absorbs light, that is, by arranging the photoelectric sensors in the glasses holder, the photoelectric sensors can collect the echo signal of the side of the nose, thereby realizing vital sign detection. Among them, multiple photoelectric sensors are arranged on the surface of the same flexible substrate, that is, multiple photoelectric sensors can be integrated through the flexible substrate, and the flexible substrate can be well adapted to the bending design of the side of the nose, and can be directly arranged in the glasses holder, so that other space designs of the glasses are not occupied, and the glasses are easy to carry, and the size is suitable for most users. After wearing the glasses, the user can detect vital signs through the side of the nose.

[0032] In order to better understand the technical solution and technical effects of the present application, specific embodiments will be described in detail below with reference to the accompanying drawings.

[0033] refer to Figure 1 and Figure 2 The figures are respectively a schematic diagram of the effect and a schematic diagram of the structure of a flexible detection device applied to glasses provided in an embodiment of the present application. The flexible detection device applied to glasses provided in an embodiment of the present application can be arranged in a glasses holder. Usually, the glasses holder of the glasses can be disassembled separately, so a flexible detection device can be arranged in the glasses holder, and can be conveniently installed on the glasses. In addition, the flexible detection device is arranged in the glasses holder so that other space of the glasses will not be occupied. The glasses are easy to carry and the size is suitable for most users. After wearing the glasses, the user can easily detect vital signs through the side of the nose.

[0034] In an embodiment of the present application, the flexible detection device applied to glasses includes: a plurality of photoelectric sensors (PD) 110. The nose part may include a nose side area 101 and a nose back area 102. Considering that the nose back area 101 has fewer blood vessels and the nose side area 101 has more blood vessels, the plurality of photoelectric sensors 110 are at least arranged in the nose side area 101. The photoelectric sensors 110 may receive the echo signal returned after the nose part absorbs light, thereby obtaining the detection result of the vital sign detection according to the echo signal.

[0035] Multiple photoelectric sensors 110 can be arranged on the surface of the same flexible substrate 100, that is, multiple photoelectric sensors 110 can be arranged based on the same flexible substrate 110, so as to realize the bending design of the side of the nose well adapted to the flexible substrate 100 and meet the requirements of actual application scenarios, refer to Figure 2 shown.

[0036] Specifically, the material of the flexible substrate 100 may be polyethylene terephthalate (PET) or polyimide (PI).

[0037] In the embodiment of the present application, considering that both sides of the nose dorsum area 102 are the nose side areas 101, the nose side area 101 includes the first nose side area and the second nose side area, and the area between the first nose side area and the second nose side area is the nose dorsum area 102. Multiple photoelectric sensors 110 can be respectively arranged in the first nose side area and the second nose side area, that is, photoelectric sensors 110 are arranged in the first nose side area and the second nose side area, so as to achieve comprehensive detection of the area with rich blood vessels in the nose, thereby improving the detection accuracy.

[0038] As an example, refer to Figure 2 As shown, two photoelectric sensors 110 are disposed in the first side nose area and the second side nose area.

[0039] In the embodiment of the present application, considering that the echo signal collected by the photoelectric sensor 110 needs to be output, the contact pad 210 can be used for electrical extraction. The material of the contact pad 210 can be selected from materials with good electrical conductivity, for example, the contact pad 210 can be a three-layer stacked structure of molybdenum, aluminum and molybdenum, the contact pad 210 can also be an indium tin oxide (ITO) material, and the contact pad 210 can also be a stacked structure formed by molybdenum, aluminum and molybdenum combined with ITO.

[0040] As a possible implementation, the contact pad 210 may be disposed in the nose dorsum region 102 , so that the contact pad 210 may be prevented from occupying the space where the photoelectric sensor 110 is disposed.

[0041] refer to Figure 2 As shown, the contact pad 210 and the photoelectric sensor 110 may be connected by a wire, and each photoelectric sensor 110 may be provided with a contact pad 210 for electrical extraction.

[0042] As another possible implementation, the contact pad 210 may be disposed in the nose side region 101. Being disposed in the nose side region 101 may facilitate subsequent bonding of the contact pad 210 and a printed circuit board, thereby achieving electrical connection between the photoelectric sensor 110 and other devices.

[0043] refer to Figure 3 As shown, the contact pad 210 is disposed in the first nose side region or the second nose side region, and the contact pad 210 and the photoelectric sensor 110 may be connected by a wire.

[0044] In an embodiment of the present application, the flexible detection device may further include a printed circuit board 300 or a chip-on-film (COF) 200. Considering that the photoelectric sensor 110 needs to be connected to the printed circuit board 300 or the chip-on-film 200 for signal transmission, the contact pad 210 provided in the flexible detection device may be used to achieve electrical connection with the printed circuit board 300 or the chip-on-film 200.

[0045] Specifically, the printed circuit board 300 may be a flexible printed circuit (FPC), so as to meet the bending design requirements of the flexible detection device at the nose.

[0046] As a possible implementation, the chip-on-film 200 is disposed in the nose dorsum region 102, and the chip-on-film 200 is electrically connected to the photoelectric sensor 110 via the contact pad 210. Figure 4 As shown, the COF 200 and the contact pad 210 are bonded in the nose dorsum region 102 , so that the echo signal of the photoelectric sensor 110 is transmitted to the contact pad 210 through the wire, and the contact pad 210 and the COF 200 are used for electrical extraction.

[0047] As another possible implementation, the printed circuit board 300 covers at least the nasal back region 102 and the nasal side region 101, and the printed circuit board 300 can also be electrically led out through the nasal back region 102. The printed circuit board 300 is provided with a bonding structure 310, and the bonding structure 310 can be provided in the nasal side region 101. The position of the bonding structure 310 and the position of the contact pad 210 overlap in the nasal side region 101, so that the bonding structure 310 and the contact pad 210 can be bonded, thereby realizing that the printed circuit board 300 is electrically connected to the photoelectric sensor 110 using the bonding structure 310 and the contact pad 210.

[0048] refer to Figure 5 and Figure 6 As shown, the contact pad 210 is disposed in the first nose side region, and the bonding structure 310 is disposed in the same first nose side region as the contact pad 210. The bonding structure 310 and the contact pad 210 are bonded in the first nose side region, so that the echo signal of the photoelectric sensor 110 is transmitted to the contact pad 210 through a wire, and then transmitted to the printed circuit board 300 by using the contact pad 210 and the bonding structure 310, and finally electrically led out through the printed circuit board 300.

[0049] In an embodiment of the present application, the nose part can absorb ambient light, and then the photoelectric sensor 110 receives the echo signal returned after the nose part absorbs the ambient light. In order to achieve more accurate detection, a light-emitting structure 120 can also be provided. The light-emitting structure 120 can be integrated into a flexible detection device. A plurality of light-emitting structures can also form a light-emitting device separately, and then be electrically connected to the flexible detection device. When the light-emitting structure 120 is integrated into the flexible detection device, the light-emitting structure 120 can be provided on the surface of the same flexible substrate 100 together with the photoelectric sensor 110. The light-emitting structure 120 can also be provided separately on other substrates. For example, the light-emitting structure 120 can be provided on the surface of a printed circuit board 300. The following is a detailed introduction:

[0050] As a possible implementation, the light emitting structure 120 is not integrated into the flexible detection device or the light emitting structure 120 is disposed on the surface of the printed circuit board 300. In this case, in order to facilitate the arrangement of the light emitting structure 120, the flexible substrate 100 has an opening in the nose back region 102, and the opening can be used to arrange the light emitting structure 120. Figure 4 or Figure 6 shown.

[0051] Specifically, the light emitting structure 120 may be disposed on a printed circuit board 300, referring to Figure 6 The light emitting structure 120 can utilize the printed circuit board 300 for electrical signal transmission.

[0052] As another possible implementation, the light emitting structure 120 and the photoelectric sensor 110 may be disposed on the surface of the same flexible substrate 100 . In this way, the flexible substrate 100 does not need to be provided with an opening, and the light emitting structure 120 can be directly disposed on the flexible substrate 100 in the nose side area 101 .

[0053] In an embodiment of the present application, the light emitting structure 120 may be disposed in the nose side area 101 . Considering that the photoelectric sensor 110 is disposed in the nose side area 101 , the light emitting structure 120 is also disposed in the nose side area 101 to provide better light.

[0054] Specifically, considering that the light emitting structure 120 is provided to provide light so that the photoelectric sensor 110 receives the echo signal after the light is absorbed by the nose, the distance between the light emitting structure 120 and the photoelectric sensor 110 cannot be too far. The light emitting structure 120 can be provided around the photoelectric sensor 110, for example, the light emitting structure 120 can be provided adjacent to the photoelectric sensor 110, and the photoelectric sensor 110 receives the echo signal of the light emitted by the light emitting structure 120, which can improve the detection accuracy and reduce the probability of inaccurate detection caused by using ambient light for detection.

[0055] The size, quantity and location of the above-mentioned photoelectric sensor 110 and light emitting structure 120 can be designed separately, and the three can be combined with each other to form a diversified design.

[0056] In the embodiment of the present application, considering that the light emitting structure 120 emits light of different wavelengths, different vital signs detection can be performed, for example, green light can realize heart rate detection, red light can realize blood oxygen detection, and infrared light can realize water content or non-invasive blood sugar detection, so when setting the light emitting structure 120, the light emitting structure 120 emitting the required wavelength can be set according to the application scenario. In addition, multiple light emitting structures 120 emitting light of different wavelengths can also be set at the same time, so as to realize comprehensive vital signs detection using a flexible detection device.

[0057] As a possible implementation, the light emitting structure 120 includes a first wavelength light emitting structure, a second wavelength light emitting structure, and a third wavelength light emitting structure, wherein the first wavelength is smaller than the second wavelength, and the second wavelength is smaller than the third wavelength. For example, light of the first wavelength corresponds to green light, light of the second wavelength corresponds to red light, and light of the third wavelength corresponds to infrared light. Therefore, when the light emitting structure 120 is provided, the first wavelength light emitting structure, the second wavelength light emitting structure, and the third wavelength light emitting structure may be provided simultaneously around the photoelectric sensor 110.

[0058] As an example, refer to Figure 5 and Figure 6 As shown, the first wavelength light emitting structure, the second wavelength light emitting structure and the third wavelength light emitting structure are both provided in the first nose side area and the second nose side area. The first wavelength light emitting structure, the second wavelength light emitting structure and the third wavelength light emitting structure can be independent light emitting diode (LED) structures.

[0059] When the photoelectric sensor 110 and the light-emitting structure 120 are both arranged on the surface of the same flexible substrate 100, in order to achieve the thinness of the flexible detection device, the photoelectric sensor 110 and the light-emitting structure 120 can both adopt a thin film structure. For example, the light-emitting structure 120 may include a light-emitting film layer, which may be an organic light-emitting semiconductor (Organic Electroluminescence Display, OLED) or a perovskite film layer that can be formed by a coating or evaporation process. The photoelectric sensor 110 includes a photosensitive film layer, and the material of the photosensitive film layer may be an organic material or quantum dots.

[0060] The specific structure of the flexible detection device is introduced below:

[0061] The flexible detection device includes not only the flexible substrate 100 and the photoelectric sensor 110 located on one side of the flexible substrate 100, but also a circuit layer 130 and a flexible packaging layer 140.

The circuit layer 130 is disposed on the surface of the flexible substrate 100, the photoelectric sensor 110 is disposed on the side of the circuit layer 130 away from the flexible substrate 100, and the flexible packaging layer 140 covers the photoelectric sensor 110. In other words, the circuit layer 130 is on the flexible substrate 100, the photoelectric sensor 110 is located on the circuit layer 130, and the flexible packaging layer 140 is located on the photoelectric sensor 110.

[0062] Specifically, the plurality of photoelectric sensors 110 may be electrically connected by using the circuit layer 130. The flexible packaging layer 140 may be made of a material having a water and oxygen isolation function, for example, the material of the flexible packaging layer 140 may be PET.

[0063] The circuit layer 130 includes a plurality of transistors, and the transistors are used to connect to the photoelectric sensor 110. Figure 7 As shown, the photoelectric sensor 110 includes a first metal layer 111, a photosensitive layer 112, and a second metal layer 113. The photosensitive layer 112 is used to receive light. The photosensitive layer 112 can detect green light, red light, and infrared light, and can also detect other characteristics such as bilirubin (400-600nm), water (1100-1300nm), blood sugar (1400-1800nm) and other vital signs through light of specific wavelengths.

[0064] The connection between the transistor and the photoelectric sensor 110 can be realized by using a top metal layer 114. The top metal layer 114 can be a stacked structure, for example, the top metal layer 114 is molybdenum-aluminum-molybdenum or titanium-aluminum-titanium. The top metal layer 114 can also be an indium tin oxide (ITO) material.

[0065] In practical applications, an electron donor layer (not shown in the figure) may be provided between the first metal layer 111 and the photosensitive layer 112 , and a hole donor layer (not shown in the figure) may be provided between the second metal layer 113 and the photosensitive layer 112 .

[0066] In the embodiment of the present application, a power supply pad 150 may also be provided on the surface of the flexible substrate 100. Figure 2 and Figure 7 As shown, the power supply pad 150 and the contact pad 210 are electrically connected by wires. The material of the power supply pad 150 can be selected from materials with good conductivity, for example, the power supply pad 150 can be a three-layer stacked structure of molybdenum, aluminum and molybdenum, the power supply pad 150 can also be an ITO material, and the power supply pad 150 can also be a stacked structure formed by molybdenum, aluminum and molybdenum combined with ITO.

[0067] It can be seen that the flexible detection device for glasses provided by the present application is arranged in the glasses holder, and the flexible detection device includes: multiple photoelectric sensors, multiple photoelectric sensors are arranged at least in the side area of ​​the nose, and the photoelectric sensors are used to receive the echo signal returned after the nose absorbs light, that is, by arranging the photoelectric sensor in the glasses holder, the photoelectric sensor can collect the echo signal of the side of the nose, thereby realizing vital sign detection. Among them, multiple photoelectric sensors are arranged on the surface of the same flexible substrate, that is, multiple photoelectric sensors can be integrated through the flexible substrate, and the flexible substrate can be well adapted to the bending design of the side of the nose, and can be directly arranged in the glasses holder, so that other space designs of the glasses are not occupied, and the glasses are easy to carry, and the size is suitable for most users. After wearing the glasses, the user can detect vital signs through the side of the nose.
