Description

Smart All-in-One Head Patch Device and Method of Operation

[0001] This patent is the result of research conducted with support from the IITP (Institute of Information & Communications Technology Planning & Evaluation) project on the construction of a robust and generalizable bioelectrical signal foundation model and the clinical utility of disease diagnostic models utilizing it. (Project No.: 2710018390, RS-2024-00443780)

[0002] The present invention relates to a smart all-in-one head patch device and a method of operating the same. More specifically, it relates to a method of monitoring and managing a user through a smart all-in-one head patch device that can be attached to the body.

[0003]

[0004] Conventional brainwave measurement systems acquired signals by attaching electrodes to the scalp via a fixed device and analyzed the acquired signals to identify abnormalities or diseases in the user. In other words, since existing brainwave measurement systems analyzed signals using specific devices provided by medical institutions, users could only check for abnormalities or diseases by visiting a medical facility and having their brainwaves measured through a specific device within the institution.

[0005] However, brainwaves can be influenced by various activities and vary depending on the user's mental or emotional state, which may result in different acquired signals. For example, brainwaves may be measured differently due to the user's fatigue, stress, or external stimuli, and this information can change in real time. Therefore, there is a need to secure brainwave information in real time, and there may be limitations to analyzing a user's condition by measuring brainwaves through specific devices within a medical institution when the user visits.

[0006] Considering the above points, the following describes a method and device that are attached to the body to measure and transmit brainwave signals in real time to perform real-time monitoring and to check the user's condition based on this.

[0054] Hereinafter, embodiments of the present specification will be examined in detail with reference to the drawings.

[0055] FIG. 1 is a diagram illustrating an example of an operating environment of a system according to an embodiment of the present specification. Referring to FIG. 1, one or more user devices (110-1, 110-2) and one or more servers (120, 130, 140) are connected through a network (1). FIG. 1 is an example for explaining the invention, and the number of user devices or servers is not limited to that shown in FIG. 1.

[0056] One or more user devices (110-1, 110-2) may be fixed terminals or mobile terminals implemented as computer systems. One or more user devices (110-1, 110-2) include, for example, smartphones, mobile phones, navigation systems, computers, laptops, digital broadcasting terminals, PDAs (Personal Digital Assistants), PMPs (Portable Multimedia Players), tablet PCs, game consoles, wearable devices, IoT (Internet of Things) devices, VR (Virtual Reality) devices, AR (Augmented Reality) devices, etc. For example, in the embodiments, the user device (110) may refer to one of various physical computer systems capable of communicating with other servers (120-140) via a network (1) using substantially wireless or wired communication methods.

[0057] Each server may be implemented as a computer device or multiple computer devices that communicate with one or more user devices (110-1, 110-2) via a network (1) to provide commands, code, files, content, services, etc. For example, the server may be a system that provides each service to one or more user devices (110-1, 110-2) connected via the network (1). As a more specific example, the server may be a computer program installed and running on one or more user devices (110-1, 110-2) and may provide the service intended by the application (e.g., providing information) to one or more user devices (110-1, 110-2) through an application. As another example, the server may distribute a file for the installation and operation of the above-described application to one or more user devices (110-1, 110-2) and receive user input information to provide a corresponding service.

[0058] FIG. 2 is a block diagram for explaining the internal configuration of a computing device (200) in an embodiment of the present specification. Such a computing device (200) may be applied to one or more user devices (110-1, 110-2) or servers (120-140) described above with reference to FIG. 1, and each device and server may have the same or similar internal configuration by adding or excluding some components.

[0059] Referring to FIG. 2, the computing device (200) may include memory (210), a processor (220), a communication module (230), and a transceiver (240). The memory (210) is a non-transient computer-readable recording medium and may include a permanent mass storage device such as RAM (random access memory), ROM (read only memory), a disk drive, an SSD (solid state drive), or a flash memory. Here, a permanent mass storage device such as a ROM, SSD, flash memory, or a disk drive may be included in the aforementioned device or server as a separate permanent storage device distinct from the memory (210). Additionally, the memory (210) may store an operating system and at least one program code (e.g., code for a browser installed and running on a user device (110), or code for an application installed on a user device (110), etc., to provide a specific service). These software components may be loaded from a computer-readable recording medium separate from memory (210). This separate computer-readable recording medium may include computer-readable recording media such as a floppy drive, disk, tape, DVD / CD-ROM drive, memory card, etc.

[0060] In another embodiment, software components may be loaded into memory (210) via a communication module (230) rather than a computer-readable recording medium. For example, at least one program may be loaded into memory (210) based on a computer program (e.g., the application described above) that is installed by files provided through a network (1) by developers or a file distribution system (e.g., the server described above) that distributes installation files for the application.

[0061] The processor (220) may be configured to process instructions of a computer program by performing basic arithmetic, logic, and input / output operations. Instructions may be provided to the processor (220) by memory (210) or a communication module (230). For example, the processor (220) may be configured to execute instructions received according to program code stored in a recording device such as memory (210).

[0062] The communication module (230) can provide a function for the user device (110) and the server (120-140) to communicate with each other through the network (1), and each of the device (110) and / or the server (120-140) can provide a function for communicating with other electronic devices.

[0063] The transceiver (240) may be a means for interfacing with an external input / output device (not shown). For example, the external input device may include devices such as a keyboard, mouse, microphone, camera, etc., and the external output device may include devices such as a display, speaker, haptic feedback device, etc. As another example, the transceiver (240) may be a means for interfacing with a device in which the functions for input and output are integrated into one, such as a touchscreen.

[0064] Additionally, in other embodiments, the computing device (200) may include more components than those of FIG. 2 depending on the nature of the device to which it is applied. For example, when the computing device (200) is applied to a user device (110), it may be implemented to include at least some of the input / output devices described above, or it may include additional components such as a transceiver, a GPS (Global Positioning System) module, a camera, various sensors, a database, etc. As a more specific example, when the user device is a smartphone, it may be implemented to include additional components such as an accelerometer or gyroscope sensor, a camera module, various physical buttons, buttons using a touch panel, input / output ports, and a vibrator for vibration, which are generally included in smartphones.

[0065]

[0066] For example, the smart all-in-one head patch system described below may operate through the computing device (200) of FIG. 2 based on the network of FIG. 1. More specifically, the smart all-in-one head patch system may include a smart all-in-one head patch that acquires brainwaves and other signals, a user device that acquires signals measured through the head patch, and a smart all-in-one head patch server that acquires and processes signals measured from a plurality of user devices. Here, each device may be a device that operates based on the computing device (200) of FIG. 2, but is not limited to such an embodiment. Additionally, each device may exchange signals based on the network of FIG. 1, but is not limited to such an embodiment. For convenience of explanation, the following description is based on the smart all-in-one head patch, the user device, and the smart all-in-one head patch server, but is not limited to these names.

[0067] As another example, the smart all-in-one head patch may operate within a system comprising at least one patch that can be attached to the body. More specifically, the smart all-in-one head patch may be equipped with an electrode patch that attaches to the body, and the smart all-in-one head patch may be positioned on the user's body in a form where the electrode patch is combined with a body part. As an example, the system may be a system that acquires signals obtained from the body through at least one patch, analyzes the acquired signals to identify abnormalities in the user's condition, or performs user monitoring. As a specific example, the system may be a sleep diagnosis system, and the sleep diagnosis system may include the smart all-in-one head patch and other patches. The sleep diagnosis system may generate sleep diagnosis information of the user based on signals obtained from the body through at least one patch, and the smart all-in-one head patch may also be included and used within the sleep diagnosis system.

[0068] However, this is merely one example and is not limited to this embodiment; the smart all-in-one head patch may be used as part of another system or utilized as a single device. For convenience of explanation, the following description is based on the smart all-in-one head patch device, but it may not be limited to a specific system or device.

[0069] FIG. 3 is a diagram illustrating a smart all-in-one head patch device and a plurality of user devices according to an embodiment of the present specification. Referring to FIG. 3, the smart all-in-one head patch (300) may be attached to the body. Specifically, the smart all-in-one head patch (300) may be connected to an electrode patch that is directly attached to the user's body, and the electrode patch may be attached to the user's body based on medical tape. The smart all-in-one head patch (300) may acquire brain waves and other related signals sensed from the electrode patch attached to the body. Here, the brain waves and other related signals acquired by the smart all-in-one head patch (300) may include EEG (Electroencephalography), EOG (Electrooculography), and oxygen saturation. Additionally, the smart all-in-one head patch (300) may further measure other signals, but may not be limited to such signals.

[0070] EEG may be a signal related to the electrical activity of the brain and may include signals of various frequency bands generated in the brain. Specifically, the signals generated in the user's brain may vary depending on the user's activities or movements, and different signals may have different frequencies. For example, EEG may include at least one of delta, theta, alpha, beta, and gamma signals. Additionally, EEG may include other signals and is not limited to a specific form. The smart all-in-one head patch (300) can measure EEG generated in the user's brain in real time and utilize the measured signals, which will be described later. Furthermore, the smart all-in-one head patch (300) can measure EOG through the conduction of the eye. EOG is a technology that measures the electrical potential between the cornea and the retina and can measure eye movements. Specifically, EOG can measure eye movements based on the potential difference between the eye and its surroundings. Additionally, EOG can measure eye movements based on the electrical difference between the front and back of the eye. The smart all-in-one head patch (300) can measure EOG signals in real time and utilize the measured signals, and this will be described later.

[0071] Additionally, the smart all-in-one head patch (300) can measure oxygen saturation. Oxygen saturation may be the oxygen concentration in the blood, and the smart all-in-one head patch (300) can obtain an oxygen saturation signal. As a specific example, the smart all-in-one head patch (300) may include a light source and a light sensor, and may obtain information on oxygen saturation in the blood by measuring infrared and visible light through the light sensor, but may not be limited to such an embodiment. The smart all-in-one head patch (300) can measure oxygen saturation-related signals in real time and utilize the measured signals, and this will be described later.

[0072] The smart all-in-one head patch (300) is attached to the forehead position on the front of the user's face to acquire the aforementioned EEG, EOG, and oxygen saturation signals. Additionally, the smart all-in-one head patch (300) can acquire other signals. For convenience of explanation, the EEG, EOG, oxygen saturation, and other signals measured through the smart all-in-one head patch (300) are referred to as head-related signals below. However, this is for convenience of explanation only and is not limited to such names.

[0073] As another example, the smart all-in-one head patch (300) can be attached to the forehead position in front of the user's face to acquire head-related signals. As an example, the smart all-in-one head patch (300) can be configured in the form of a sleeping pad and attached to the eye position in front of the user's face. As another example, the smart all-in-one head patch (300) can be attached to the user's body in a combined form with a hat, a hair band, or other wearable device to acquire head-related signals, and is not limited to a specific form.

[0074] As another example, multiple smart all-in-one head patches (300) may be attached to the body. It may also be possible for the smart all-in-one head patches (300) to be attached to the front, back, and sides of the body, respectively. Head-related signals can be obtained from each of the multiple smart all-in-one head patches (300) and compared, and since head-related signals are obtained based on the compared signals, the accuracy of head-related signal measurement can be increased. However, it may not be limited to this form. For convenience of explanation, the following description is based on the form in which the smart all-in-one head patch (300) is attached to the forehead position in front of the user, but it may not be limited to this.

[0075] Here, the smart all-in-one head patch (300) being attached to the user's body may be a case where the electrode patch and medical tape are attached to the user's body, and the electrode patch is connected to the smart all-in-one head patch (300) so that the smart all-in-one head patch (300) is positioned on the user's body, and for convenience of explanation, it is described below that the smart all-in-one head patch (300) is attached to the user's body.

[0076] The smart all-in-one head patch (300) can acquire additional information other than head-related signals. For example, the smart all-in-one head patch (300) can acquire additional information regarding the user's body temperature or the moisture content of the skin. The user's body temperature or the moisture content of the skin is information that can affect the head-related signals as interference signals when acquiring head-related signals through the smart all-in-one head patch (300). By acquiring this additional information, the smart all-in-one head patch (300) can improve the accuracy of head-related signal measurement. As a specific example, correction for head-related signals may be necessary when the user's body temperature rises slightly, such as in midsummer, or when there is a lot of moisture on the surface due to sweat. The smart all-in-one head patch (300) can improve the accuracy of head-related signal measurement by acquiring this additional information.

[0077] As another example, the smart all-in-one head patch (300) can acquire user status information and other information. Specifically, head-related signals can be acquired by considering the state of the user using the smart all-in-one head patch (300). For example, head-related signals may differ depending on whether the user is in a sleeping state, in a state of concentration (e.g., performing work), in a state of rest, and other lifestyle patterns of the user, and it may be necessary to acquire information that reflects this. Additionally, the smart all-in-one head patch (300) can acquire user status information from the outside and reflect it in signal measurement or directly sense the user's state, and is not limited to a specific form.

[0078] The smart all-in-one head patch (300) can transmit the acquired signal described above to a user device (410, 420, 430). For example, the user device (410, 420, 430) is a device used by a user who has attached the smart all-in-one head patch (300), and may be a smartphone (410), a tablet (420), a smart watch (430), or other devices, and is not limited to a specific form. However, for convenience of explanation, the following description is based on a tablet (420) among the user devices, but it may not be limited thereto. Afterward, the user device (410, 420, 430) can perform monitoring based on the signal acquired from the smart all-in-one head patch (300). Additionally, the user device (410, 420, 430) can transmit the signal acquired from the smart all-in-one head patch (300) to a server (or system). As another example, the user device may be a device that operates within a preset distance from the smart all-in-one head patch (300). As a specific example, the user device may be a smart watch (430). Here, the user device may obtain user status information and other information within a preset distance from the smart all-in-one head patch (300), and is not limited to the above-described embodiment. As an example, among the user devices, the smart watch (430) may provide user status information and other information to the smart all-in-one head patch (300) within a preset distance from the smart all-in-one head patch (300), but is not limited to such embodiment.

[0079] FIG. 4 is a diagram illustrating a smart all-in-one head patch system according to an embodiment of the present specification. Referring to FIG. 4, the smart all-in-one head patch system may include a smart all-in-one head patch (300), a user device (420), and a cloud (or server, 500). Additionally, the smart all-in-one head patch system may include other configurations and may not be limited to a specific form. Referring to FIG. 4(a), the user device (420) may obtain head-related signals from the smart all-in-one head patch (300). That is, the smart all-in-one head patch (300) may obtain EEG, EOG, oxygen saturation, and other signals, but is not limited to a specific embodiment.

[0080] In this disclosure, the term "head-related signal" may refer to EEG, EOG, SpO₂, and other groups of signals. It may also include signals that can be measured in relation to brain waves or brain function. In this disclosure, for convenience of explanation, the term is used, but it is not limited to this term and may include various signals.

[0081] Additionally, the user device (420) may acquire additional information. For example, the user device (420) may acquire the aforementioned head-related signals from the smart all-in-one head patch (300) and display the information to provide it to the user. Here, the user device (420) may acquire the aforementioned user state information or other user-related information from an external device or server and display it by further reflecting the information. For example, in FIG. 4(a), the user device (420) may display the user state information (421) by reflecting it. The user state information (421) may be state information based on sleep state, concentration state, rest state, and other user lifestyle patterns, and may be a case where the user's mental / emotional state changes. Additionally, the smart all-in-one head patch (300) may measure head-related signals in real-time or based on a preset cycle. As another example, the smart all-in-one head patch (300) may measure head-related signals when a sudden state change occurs due to event triggering, but is not limited to a specific form.

[0082] The user device (420) may further display average information (422), long-term monitoring information (423), and other information based on the signal measured as described above. For example, the user device (420) may provide analysis information based on a preset period. As a specific example, the user device (420) may provide at least one of daily information, weekly information, monthly information, and long-term based information, and is not limited to a specific form. That is, the user device (420) may acquire head-related information from the smart all-in-one head patch (300) based on real-time or a preset period, derive analysis information from the head-related information, and provide it to the user, thereby enabling the user to recognize the correlation between the head-related signal and the user's state.

[0083] As another example, referring to FIG. 4(b), a user device (420) can transmit head-related information obtained from a smart all-in-one head patch (300) to a cloud (500). Here, the cloud (500) can obtain signals from each of the multiple user devices (420) that obtain signals from the smart all-in-one head patch (300), perform analysis, and transmit the analyzed information to the user device (420). As another example, the cloud (500) can perform training on a state monitoring learning model based on the head-related information obtained from multiple user devices (420). Afterward, the cloud (500) can transmit the learned state monitoring learning model to each user device (420). Each user device (420) can provide head-related information obtained from the user as input to the state monitoring learning model to perform inference and automatically derive whether the user state is abnormal as an output value, which will be described later.

[0084] As another example, the smart all-in-one head patch (300) can operate in conjunction with a user device (420). For example, when the smart all-in-one head patch (300) is attached to the user's forehead and turned on, the user device (420) can transmit setting information related to the head-related signals acquired by the smart all-in-one head patch (300) to the smart all-in-one head patch (300). For example, the setting information may include at least one of the following: information regarding the total time during which the smart all-in-one head patch (300) acquires head-related signals, sensing cycle information, monitoring event information for monitoring the user's condition, information on the user's body parts, and other information. That is, the setting information may be setting information regarding the method by which the smart all-in-one head patch (300) acquires head-related signals, and said setting information may be set by the user device (420) and transmitted to the smart all-in-one head patch (300). However, this is merely one example and is not limited thereto. After that, the smart all-in-one head patch (300) can sense and transmit arm-related signals according to the setting information obtained from the user device (420).

[0085] FIGS. 5a to 5c are drawings illustrating the structure of a smart all-in-one head patch according to an embodiment of the present specification. Referring to FIG. 5a, the smart all-in-one head patch (300) may include at least one electrode (311-1, 311-2, 311-3, 311-4, 311-5, 311-6), and each of the at least one electrode (311-1, 311-2, 311-3, 311-4, 311-5, 311-6) may be connected to at least one sensing electrode (331-1, 331-2, 331-3, 331-4, 331-5, 331-6).

[0086] Here, an electrode patch comprising at least one sensing electrode (331-1, 331-2, 331-3, 331-4, 331-5, 331-6) may be attached to the body and may perform sensing to acquire the EEG and EOG signals described above. That is, the electrode patch comprising at least one sensing electrode (331-1, 331-2, 331-3, 331-4, 331-5, 331-6) may detect changes in electrical signals, and when a change in electrical signal is sensed, the corresponding sensing information may be transmitted to the connected electrode. Each of at least one electrode (311-1, 311-2, 311-3, 311-4, 311-5, 311-6) can acquire sensing information from at least one connected sensing electrode (331-1, 331-2, 331-3, 331-4, 331-5, 331-6) and can transmit the sensing information to a process connected to the electrode patch, and based on this, EEG and EOG signals can be sensed. This will be described later. In addition, the smart all-in-one head patch (300) may further include a body part (330). The body part (300) can be connected to an electrode patch including at least one electrode (311-1, 311-2, 311-3, 311-4, 311-5, 311-6). Here, the body part (330) may be a component located outside the processor and other components to protect each component, and may not be limited to such a name. For example, the smart all-in-one head patch (300) may be attached to the body and prevent detachment using a material of silicon gel and silicon elastomer. Silicon elastomer may be a material with excellent elasticity, absorbency, and tensile strength. Here, the smart all-in-one head patch (300) may be attached to the surface of the body based on a medical tape combined with an electrode patch. The smart all-in-one head patch (300) may be a flexible material composed of silicon gel and silicon elastomer, but is not limited thereto.For example, the smart all-in-one head patch (300) may be formed in the shape of a flexible material based on the above description. As another example, the smart all-in-one head patch (300) may be a functional plastic or other form. That is, the smart all-in-one head patch (300) may not be limited to a specific material or form, and may be various forms that sense signals from the user's body and operate smoothly.

[0087] Additionally, FIGS. 5b and 5c may show the structure of an all-in-one head patch (800). However, the structure may not be limited to such a structure, and the all-in-one head patch (800) of FIGS. 5b and 5c may be the all-in-one head patch (300) of FIG. 5a. For example, the all-in-one head patch (800) may include six electrodes (811, 812, 813, 814, 815, 816), and the six electrodes (811, 812, 813, 814, 815, 816) may be flexible electrodes. As a specific example, the flexible electrodes having a serpentine pattern as the six electrodes (811, 812, 813, 814, 815, 816) of the all-in-one head patch (800) may be ENIG (electroless nickel immersion gold) electrodes composed of two layers of electroless nickel and immersion gold on an electronic circuit board (PCB), and the gold may come into contact with the user's body, but are not limited to this embodiment. As an example, the electroless nickel may form a nickel layer on copper so that the copper does not come into direct contact with the gold, and the immersion gold may form a layer of thin gold on the nickel, and the gold may be coated on the nickel surface based on an immersion method. Here, the immersion gold may have high electrical conductivity performance, and based on this, it may come into contact with the user's body to acquire the user's biosignal. That is, by allowing gold with high electrical conductivity to come into contact with the user's body, the accuracy of acquiring the user's biosignal can be improved. Additionally, the six electrodes (811, 812, 813, 814, 815, 816) may be connected to a copper conductive layer (820) or other conductive layers. A signal sensed through the conductive layer (820) may be transmitted to the connection portion (830) of the electrode patch.The back side of the connection part (830) of the electrode patch is composed of an ENIG electrode, and the front side is composed of a flat flexible cable (FFC), so that a path can be formed for transmitting a signal sensed from the patch device (800).

[0088] Additionally, as an example, the all-in-one head patch (800) may be configured to a size that is attached to the user's body as a header patch. As a specific example, it may have a size of 76 (L) x 26 (M) mm, but this is merely one example and is not limited thereto. Additionally, a polyamide layer may be formed between the conductive layer (820) in the all-in-one head patch (800). As another example, the all-in-one head patch (800) may further include an area equipped with a Photoplethysmography (PPG) sensor. The PPG sensor can measure changes in blood flow through a light source and thereby measure the oxygen saturation described above. Specifically, oxygen saturation may be the oxygen concentration in the blood, and the PPG sensor may include a light source and a light sensor, and may obtain information on oxygen saturation in the blood by measuring infrared and visible light through the light sensor. Additionally, as an example, the PPG sensor may further sense blood pressure or other information based on changes in blood flow, and is not limited to a specific form.

[0089] Additionally, referring to FIG. 5c, the basic structure of the all-in-one head patch (800) may be the same as FIG. 5b. However, the shape of the six electrodes (811, 812, 813, 814, 815, 816) in FIG. 5c may be configured differently from FIG. 5b. Specifically, each of the six electrodes (811, 812, 813, 814, 815, 816) may be a serpentine pattern, but may be in the same shape as FIG. 5c. However, it is not limited to this, and other types of patterns may also be possible.

[0090] Additionally, referring to FIG. 5c, the connection portion (830) of the electrode patch may include a signal transmission portion (831) that transmits a signal to a region composed of electrodes within a flexible region, and an external connection portion (832) composed of electrodes within a rigid region that can be connected to an external device. Specifically, the signal transmission portion (831) may be a part that transmits signals obtained from six electrodes (811, 812, 813, 814, 815, 816) within the connection portion (830) of the electrode patch, and the signal transmission portion (831) within the flexible region may be formed as an electrode. The external connection portion (832) may be located at the end of the signal transmission portion (831), and the external connection portion (832) may be a part that is connected to a driving portion within the all-in-one head patch (800) through coupling with electrodes and circuits. The external connection part (831) may be made of a rigid material because it must be connected to the drive part of the all-in-one head patch (800) or an external device. Specifically, if the external connection part (831) is made of a flexible material, the connection to the external device may not be smooth. For example, if the area of ​​the external connection part (831) is bent or folded, the part that needs to be connected to the terminal of the external device may not be connected, and a defect may occur in the terminal. Considering the above-mentioned point, the external connection part (832) may be made of a rigid material in a fixed form as a support area, and based on this, it can be connected to the drive part of the patch device to the external device without defect. On the other hand, the signal transmission part (831) may be made of a flexible material because it is not an area that is directly connected to the drive part or the terminal of the external device, even though an electrode exists therein. Here, the signal transmission part (831) can be bent so that the external connection part (832) moves to a position where it contacts the driving part or the external terminal, thereby supporting the connection of the external connection part (832), which will be described later.Additionally, the all-in-one head patch (800) may be provided with at least one fixing groove (840). The at least one fixing groove (840) may be a part configured to allow a substrate composed of electrodes within the patch device (800) to be fixed to a medical tape (or other flexible material, 850). For example, the medical tape (850) or other flexible materials may be elastic materials, and thus may be easily contracted and expanded. As another example, a case may be considered where the measurement value differs for each patch device when the medical tape (850) or other flexible materials are moved slightly. Considering the above points, it is necessary for the medical tape (850) and the substrate inside the all-in-one head patch (800) to be aligned in a certain position, and the fixing groove (840) may be a part that allows the substrate within the all-in-one head patch (800) and the medical tape to be aligned in a fixed position. Considering the above-described points, the all-in-one head patch (800) may be provided with at least one fixing groove (840), and the substrate and medical tape may be sequentially overlapped based on the fixing groove (840), thereby allowing the all-in-one head patch (800) of the same shape to be manufactured. In addition, other details may be the same as those in FIG. 5b.

[0091] FIG. 6 is a diagram showing the structure of a smart all-in-one head patch according to one embodiment of the present specification. However, the structure may not be limited to that of FIG. 6. Referring to FIG. 6(a), the upper part of the smart all-in-one head patch (300) may include at least one of an electrode connector (311), an analog digital converter (ADC, 312), a processor (313), a voltage regulator (314), a voltage divider (315), LEDs for indicating device status (316), a reverse voltage protection diode (317), an ESD protection diode (318), a wireless battery charging module (319), a battery connecting pad (320), a switch (321), and a connector for firmware flashing (322).

[0092] For example, at least one electrode (311) may be included in the smart all-in-one head patch (300). Each of the at least one electrode (311-1, 311-2, 311-3, 311-4, 311-5, 311-6) may be connected to at least one sensing electrode (331-1, 331-2, 331-3, 331-4, 331-5, 331-6) and may be attached to the body through the at least one sensing electrode (331-1, 331-2, 331-3, 331-4, 331-5, 331-6) to measure head-related signals. Specifically, at least one of the EEG and EOG signals can be obtained through at least one sensing electrode (331-1, 331-2, 331-3, 331-4, 331-5, 331-6). Additionally, as an example, the smart all-in-one head patch (300) may further include a sensor (not shown) for measuring oxygen saturation. Specifically, the sensor for measuring oxygen saturation may include a light source and a light sensor, but may not be limited to a specific form. The head-related signal obtained through at least one electrode (311-1, 311-2, 311-3, 311-4, 311-5, 311-6) and the sensor can be converted into a digital signal through an ADC (312), and the converted digital signal can be controlled through a processor (313). For example, the processor (313) may be a BLE microprocessor, but is not limited thereto. A BLE (Bluetooth Low Energy) microprocessor may be a small microprocessor that supports low-power Bluetooth communication and may support wireless applications based on low power. For example, the smart all-in-one head patch (300) may be a device that operates based on low power, and the above-described BLE microprocessor may be used, but is not limited thereto.

[0093] The processor (313) is a single chip in which a CPU, memory, RF transceiver, and various I / O devices are implemented, and can store digital signals modified by the ADC (312) and transmit them to an external device. Additionally, the smart all-in-one head patch (300) may include a voltage regulator (314) to supply power to the processor (313) and other components. For example, the voltage regulator (314) may be composed of a first voltage regulator (314-1) and a second voltage regulator (314-2), each of which can be adjusted to a different voltage. For example, the first voltage regulator (314-1) may supply a voltage of 1.8V, and the second voltage regulator (314-2) may supply a voltage of 5V. However, this is merely one example and is not limited thereto. The voltage divider (315) may distribute the voltage supplied to the processor (313) and the voltage for monitoring the battery level, and the LED (316) may indicate the operating status of the smart all-in-one head patch (300). For example, the LED (316) may remain in a turned-on state when the smart all-in-one head patch (300) senses a signal, but is not limited to such an embodiment. Additionally, the reverse voltage protection diode (317) may be a diode that protects the circuit when a reverse voltage is applied due to the power supply being connected with the wrong polarity within the smart all-in-one head patch (300), and the ESD protection diode (318) may be a diode that performs the function of protecting the smart all-in-one head patch (300) from electrostatic discharge (ESD).

[0094] Additionally, the smart all-in-one head patch (300) may include a wireless battery charging module (319), thereby enabling the smart all-in-one head patch (300) to be charged wirelessly. Additionally, the smart all-in-one head patch (300) may include a battery connection pad (320), thereby enabling wired charging. That is, the smart all-in-one head patch (300) can be charged and operated by receiving power from an external source through the charging module. Additionally, the smart all-in-one head patch (300) may include a switch (321) that controls whether the smart all-in-one head patch (300) is operating. Additionally, the smart all-in-one head patch (300) may further include a firmware flashing connector (322) that updates an application or firmware within the smart all-in-one head patch (300).

[0095] Additionally, referring to FIG. 6(b), the bottom of the smart all-in-one head patch (300) may include an area (323) where a coil is located, and wireless charging may be performed through the coil. Additionally, the area (323) where the coil is located may include a wireless charging connecting pad (324), through which charging power can be supplied to the smart all-in-one head patch (300).

[0096] Additionally, as an example, the smart all-in-one head patch (300) may further include a PPG (Photoplethysmography) sensor (325). The PPG sensor (325) can measure changes in blood flow through a light source and thereby measure the oxygen saturation described above. Specifically, oxygen saturation may be the oxygen concentration in the blood, and the PPG sensor (325) may include a light source and a light sensor, and may obtain information on oxygen saturation in the blood by measuring infrared and visible light through the light sensor. Additionally, as an example, the PPG sensor (235) may further sense blood pressure or other information based on changes in blood flow, and is not limited to a specific form.

[0097] Additionally, at least one electrode (311-1, 311-2, 311-3, 311-4, 311-5, 311-6) inside the smart all-in-one head patch (300) may be an electrode for measuring ECG or EOG, and may be a gold electrode composed of gold, but is not limited thereto and may be an electrode of another material. The wireless charging coil may be a configuration that performs battery charging, and based on this, the smart all-in-one head patch (300) may be charged.

[0098] Additionally, as an example, the smart all-in-one head patch (300) may be composed of silicone gel and silicone elastomer, and may contain polyimide and copper trace inside. Here, the polyimide may be a polymer material having thermal stability and high mechanical strength. This allows the polyimide to deform together when the smart all-in-one head patch (300) is stretched or bent when the smart all-in-one head patch (300) is attached to the body, thereby allowing the smart all-in-one head patch (300) to remain attached to the body without falling off. More specifically, an electrode patch and a medical tape may be attached to the user's body, and the electrode patch may be connected to the smart all-in-one head patch (300). Thus, the bottom of the smart all-in-one head patch (300) may be present on the user's body and may deform together based on the material as described above.

[0099] Additionally, copper tracking can enable the smart all-in-one head patch (300) to track and transmit signals acquired through the high conductivity of copper. Furthermore, as an example, a battery can serve to maintain power to transmit signals acquired by the smart all-in-one head patch to a user device. As an example, the smart all-in-one head patch (300) is a low-power device and can maintain power for a long period through a battery. As another example, the battery may be attached to the body and charged according to the user's movement. As described above, since the smart all-in-one head patch (300) is a low-power device, it may operate using power charged according to the user's movement while attached to the body, but it may not be limited to such embodiments.

[0100] FIG. 7 is a drawing illustrating a smart all-in-one head patch according to an embodiment of the present specification. Referring to FIG. 7, the smart all-in-one head patch (300) may further include a skin model portion (332). Here, the skin model portion (332) may be a configuration attached to a user based on a medical tape described below. For example, the skin model portion (332) may be a configuration located outside the smart all-in-one head patch (300) to increase the strength of attachment to the body. More specifically, the smart all-in-one head patch (300) needs to be attached to the body to acquire head-related signals in real time. Here, the smart all-in-one head patch (300) can measure signals through an electrode patch and needs to be in close contact with the body to improve measurement accuracy. The skin model portion (332) may be configured to be combined with the electrode patch at a fixed position based on a medical tape, and may be a configuration that allows the electrode patch to be in close contact with the body. For example, the skin model part (332) may be in the form of a medical tape with a headband, sleep mask, and other devices further combined, but may not be limited to a specific form.

[0101] Additionally, as an example, the smart all-in-one head patch (300) may be provided with a polyimide of a preset shape. Each of the components of FIG. 6 may be disposed within the polyimide, as described above. Here, as an example, the components of the polyimide may include components for acquiring a signal from the user's body, performing processing, and transmitting the signal to the outside. As another example, the polyimide may be deformed according to the relaxation or contraction of the smart all-in-one head patch (300). More specifically, the smart all-in-one head patch (300) may be composed of a silicone gel as described above, and the silicone gel may relax or contract. For example, the smart all-in-one head patch (300) may relax or contract depending on the location where it is attached, and a part of it may be bent. That is, the shape of the smart all-in-one head patch (300) may be partially deformed depending on the location on the body where it is attached, thereby increasing the strength of attachment to the body.

[0102] FIG. 8 is a diagram illustrating a method for analyzing head-related signals based on machine learning according to an embodiment of the present specification. Referring to FIG. 8, a smart all-in-one head patch system can provide analysis information on head-related signals based on AI / ML. Here, head-related signals refer to EEG, EOG, SpO₂, and other groups of signals as described above, and may be a concept that includes signals that can be measured in relation to brain waves or brain function.

[0103] The smart all-in-one head patch (300) can acquire head-related signals and transmit them to a user device, as described above. Here, the user device can perform inference based on the acquired signals in an embedded algorithm or a monitoring learning model (S810) to derive analysis information regarding the head-related signals (S820). For example, the user device may be equipped with an embedded algorithm or a monitoring learning model. Here, the embedded algorithm or the monitoring learning model may be a learning model learned based on analysis information regarding the user's head-related signals. As another example, the monitoring learning model may be a learning model learned to derive signal analysis information based on other user information and a specific state (e.g., sleep state).

[0104] As a specific example, the user device may acquire head-related signals from the smart all-in-one head patch (300) and compare them with information stored in a database. Additionally, the user device may perform inference based on the preprocessed information after performing filtering, wavelet noise removal, and other preprocessing operations. For example, the learning model may perform inference based on rescaling or CNN (convolutional neural network) classification operations, and through this, perform analysis on the head-related signals acquired to provide analysis information about the current user. Afterward, the user device may calculate period information corresponding to a certain period based on the analysis information (S830) and display the information to the user device (S840). For example, the user device may generate score information based on the analysis information and display the score information to the user device. That is, the user device may provide analysis information to the user by analyzing the signals acquired from the smart all-in-one head patch (300) based on AI / ML, and is not limited to a specific form. Here, for example, a user device can receive a cloud-based pre-trained state monitoring learning model, and can derive an output value indicating whether there is an abnormality by providing head-related information as input to the said state monitoring learning model.

[0105] Additionally, for example, the signal obtained from the smart all-in-one head patch (300) can be utilized as information within a specific system. For example, the specific system may be a sleep diagnosis system, but is not limited to such an embodiment. That is, the smart all-in-one head patch (300) can be utilized as a device within a specific system that utilizes head-related signals and is not limited to a specific form.

[0106] However, for the convenience of explanation, the following description is based on a sleep diagnosis system. For example, the sleep diagnosis system may further include a smart all-in-one head patch (300) and at least one other patch. Here, each patch can be attached to the user's body to acquire signals related to the user's condition. The sleep diagnosis system can analyze and diagnose the user's sleep state based on the signals acquired from the smart all-in-one head patch (300) and other patches. Here, the sleep diagnosis system is a system that operates based on the smart all-in-one head patch (300), other patches, and a user device, allowing the user to use it in real time without visiting a specific medical institution, and thereby can provide highly accurate user analysis information.

[0107] In addition, the sleep diagnosis system can update a learning model based on signals measured by the user, and provide the user with information for improving sleep diagnosis by analyzing and diagnosing the user's sleep state according to the updated learning model.

[0108] More specifically, the smart all-in-one head patch (300) can input time-series data regarding the acquired signal into a CNN or LSTM (Long Short-Term Memory) based classifier. For example, the acquired signal may be EEG, EOG, SpO₂, and other signals as described above. The sleep diagnosis system can input time-series data regarding the acquired signal into a CNN or LSTM based classifier to estimate the AHI (Apnea-Hypopnea Index) or to automatically classify sleep stages (N1, N2, REM, etc.) and update the learning model. As a specific example, signal changes can be measured based on the time-series data of the head-related signals (e.g., EEG, EOG, SpO₂) described above.
