Description

[Technical Field]

[0001] The present invention relates to the field of traditional Chinese medicine technology, specifically to a biofeedback smart headband for AI cognitive coaching. [Background technology]

[0002] With the development of artificial intelligence (AI) and biofeedback technology, cognitive state adjustment devices based on physiological signals are finding widespread applications in areas such as mental health and improving learning efficiency. However, current technologies still have the following challenges:

[0003] First, traditional Chinese medicine theory is not fully integrated with modern biofeedback technology. Most existing biofeedback devices are based on Western medical theory and lack the systematic application of traditional Chinese medicine's meridian and acupoint theories, making it difficult to achieve the overall goal of "integrating the body and mind." For example, the electrode placement of existing EEG collection devices is not aligned with traditional Chinese medicine's head-based meridian-diagnosis theory, making it difficult to accurately capture bioelectric signals corresponding to meridians and acupoints. Electrodermal response detection is also not aligned with traditional Chinese medicine theories such as "the heart governs God," making it difficult to multidimensionally reflect emotional and cognitive states.

[0004] Second, there are limitations to the collection and integration capabilities of multidimensional physiological signals. Existing devices typically only collect signals such as EEG, electrical skin conduction, and heart rate variability individually, and lack the ability to simultaneously collect and analyze these multidimensional data. This makes it difficult to build a cognitive state assessment model that conforms to traditional Chinese medicine symptom diagnosis theory (e.g., quantitatively assessing symptoms such as cognitive fatigue and emotional imbalance).

[0005] Furthermore, the feedback intervention method lacks the characteristics of traditional Chinese medicine. Traditional tactile feedback mechanisms often use a single frequency or intensity of stimulation, which cannot mimic the traditional Chinese acupuncture and moxibustion principles of "gaining qi sensation" and "replenishing deficiency and draining fullness," resulting in a lack of personalized and precise intervention methods. In addition, few current devices combine AI technology to generate real-time feedback methods based on physiological signals, making it difficult to meet the dynamic adjustment needs of combining traditional Chinese and Western medicine.

[0006] In addition, there is a contradiction between wearing comfort and signal collection stability. Some biofeedback devices use wet electrode technology, which requires conductive gel, resulting in problems such as wearing discomfort and skin irritation. At the same time, the electrode placement does not follow ergonomics or traditional Chinese medicine head circumference size theories, resulting in unstable signal collection and discomfort during wearing, limiting long-term use scenarios. Summary of the Invention [Problem to be solved by the invention]

[0007] The object of the present invention is to solve at least to some extent the above-mentioned technical problems. [Means for solving the problem]

[0008] The biofeedback smart headband for AI cognitive coaching according to the present invention comprises a head-mounted main body structure, which includes an EEG sensor array conforming to the head division theory of traditional Chinese medicine, a skin electrodermal response module based on the meridian and acupoint principle, a heart rate variability detection unit incorporating pulse diagnosis theory, a low-power microprocessor, and a tactile feedback mechanism simulating acupuncture and moxibustion stimulation.

[0009] The electrode arrangement of the EEG sensor array corresponds to the Chinese herbal acupuncture stimulation areas of the frontal region (Yintang and Shenting points), temporal region (Taiyang and Zhugu points), and parieto-occipital region (Baihui and Fengchi points), and uses dry electrode technology to simultaneously collect bioelectrical signals from multiple brain regions and meridians and acupoints.

[0010] The measurement site of the electrodermal response module is selected to be the Laogong point area on the hand or the heart area reflex point on the ear, and a body surface meridian circuit is formed by the flexible electrodes integrated in the ear hook and the conductive rubber electrodes on the front end of the main body.

[0011] The heart rate variability detection unit uses an optical sensor to acquire the forehead pulse wave signal, and the sampling frequency meets the dynamic detection needs of traditional Chinese medicine pulse diagnosis.

[0012] The tactile feedback mechanism includes vibration actuators distributed at positions corresponding to acupuncture points such as Tou Wei and Si Shen So, and simulates the qi-gaining sensation of acupuncture and moxibustion by using vibration pulses of different frequencies.

[0013] Preferably, the head-mounted body structure has an adjustable headband designed with reference to the head circumference size theory of traditional Chinese medicine, the body material is selected from biocompatible silicone rubber and alloy frame, and the electrode contact position conforms to the head meridian positioning theory of traditional Chinese medicine.

[0014] Preferably, the EEG sensor array includes 8 to 16 electrodes, of which the forehead electrodes correspond to the circulation areas of the Du meridian and the bladder meridian, the temporal electrodes correspond to the distribution area of ​​the Shaoyang meridian, and the parieto-occipital electrodes correspond to the intersection area of ​​the Taiyang meridian and the Du meridian, forming a signal collection network suitable for Chinese medicine head meridian differentiation syndrome.

[0015] Preferably, the electrodermal response module selects the Shenmen area (wrist), which is the original point of the heart meridian, or the heart area of ​​the concha cavity as an auxiliary measurement point based on the traditional Chinese medicine theory that "the heart governs the spirits," and combines it with the Renmai acupoint area on the forehead to form a multidimensional emotional arousal detection circuit.

[0016] Preferably, the heart rate variability detection unit extracts the photoplethysmographic signal from the forehead, combines it with the three-element analysis model of "stomach qi, shen qi, and endurance qi" in traditional Chinese medicine pulse diagnosis, and outputs HRV parameters reflecting the autonomic nervous balance state.

[0017] Preferably, the vibration frequency range of the tactile feedback mechanism covers the frequency bands of alpha waves (8-13 Hz) and beta waves (14-30 Hz), corresponding to the Chinese medicine adjustment theory of "stillness nourishes spirit, movement moves qi," and stimulates acupoints on the head by combining different vibration frequencies to improve cognitive state. In addition, the biofeedback smart headband for AI cognitive coaching disclosed in this utility model may have the following additional technical features:

[0018] Preferably, the microprocessor has a built-in Chinese medicine symptom discrimination algorithm, and constructs a cognitive fatigue and emotional imbalance symptom model that conforms to the Chinese medicine symptom diagnosis theory based on the energy distribution of EEG delta / theta / alpha / beta waves, the amplitude of skin conductance response, and the time domain parameters of heart rate variability.

[0019] Preferably, the electrode arrangement within the main body structure is in accordance with the traditional Chinese medicine holography theory of "left governs the liver, right governs the lungs, and forehead governs the gods," with the left temporal electrode corresponding to the liver meridian reflex zone, the right corresponding to the lung meridian reflex zone, and the central forehead electrode corresponding to the regulating area of ​​the Du meridian Yuanshenzhifu.

[0020] Preferably, the vibration intensity of the tactile feedback mechanism is divided into two modes: supplementation (low-intensity continuous vibration) and drainage (high-intensity intermittent vibration), which corresponds to the regulatory principle of Chinese acupuncture and moxibustion that "if there is deficiency, supplement it, and if there is fullness, drain it," and improves cognitive function through acupoint stimulation. [Effects of the Invention]

[0021] The present invention can provide the following beneficial effects: (1) Multidimensional precision testing based on traditional Chinese medicine theory The EEG sensor array uses electrodes positioned based on traditional Chinese medicine head segment theory (the frontal region corresponds to the Du meridian and bladder meridian, and the temporal region corresponds to the Shaoyang meridian). Combined with dry electrode technology, it simultaneously collects bioelectric signals from multiple brain regions and meridians and acupoints, improving the accuracy of signal collection and its relevance to traditional Chinese medicine diagnosis. The electrodermal response module selects meridian reflex points such as the Laogong point on the hand and the heart area on the ear, and constructs a surface meridian circuit based on the theory that "the heart governs the gods," thereby realizing multidimensional detection of emotional arousal. The heart rate variability detection unit quantifies the autonomic nervous system balance state through the forehead photoplethysmography signal and combines it with the three-element model of "stomach qi, shen qi, and endurance qi" of traditional Chinese medicine pulse diagnosis, providing a traditional Chinese medicine theoretical basis for the assessment of cognitive status. (2) Individualized tactile feedback intervention combining Chinese and Western medicine The tactile feedback mechanism combines vibration frequency (covering the alpha and beta wave bands) and intensity (supplement and drainage modes) to simulate the acupuncture-moxibustion sensation of gaining qi and the regulatory principle of "supplementing when deficiency occurs, draining when fullness occurs." It improves cognitive function by stimulating acupuncture points such as Tou Wei and Si Shensong, filling the gap in traditional Chinese medicine intervention methods that were lacking in previous devices. The microprocessor's built-in Chinese medicine symptom discrimination algorithm constructs symptom models such as cognitive fatigue and emotional imbalance based on multidimensional physiological data, and combines them with an AI cognitive coaching system to realize dynamic feedback plan generation for "harmonizing body and mind," thereby improving the accuracy and level of individualization of intervention. (3) Optimizing wearing comfort and signal stability The head-mounted main body structure features an adjustable headband designed based on traditional Chinese medicine head circumference size theory, and uses biocompatible silicone rubber and an alloy frame. The electrode contact position conforms to the head positioning theory, ensuring comfort while also ensuring stable and consistent biosignal collection. Dry electrode technology avoids the reliance on conductive gel of wet electrodes, reduces skin irritation, and is suitable for long-term wear. (4) Innovative architecture based on multidimensional data fusion and AI integration By integrating multidimensional data collection modules such as electroencephalograms, electrical skin conductance, and heart rate variability, an evaluation model that conforms to the theory of Chinese medicine symptom diagnosis is constructed through a microprocessor, realizing quantitative conversion from physiological signals to Chinese medicine symptoms. The wireless communication module interacts with the AI ​​cognitive coaching system to form a closed-loop regulation system of "signal collection - Chinese medicine diagnosis - AI decision-making - tactile feedback", promoting the intelligent development of cognitive intervention technology that combines Chinese and Western medicine.

[Figure 2] FIG. 2 is an operational flow diagram of the biofeedback smart headband for AI cognitive coaching according to the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention, in conjunction with the drawings of the embodiments of the present invention. Obviously, the described embodiments are not all embodiments, but only some embodiments of the present invention. Needless to say, any other embodiments that a person skilled in the art can obtain based on the embodiments of the present invention without any creative ingenuity will fall within the scope of the claims of the present invention. [Example]

[0024] An embodiment of the present invention will be described in detail with reference to FIGS. The biofeedback smart headband for AI cognitive coaching according to the present invention is: The device has a head-mounted main body structure, and is equipped with an electroencephalogram (EEG) sensor array conforming to the head division theory of traditional Chinese medicine, a skin electrodermal response module based on the meridian and acupoint principle, a heart rate variability detection unit incorporating pulse diagnosis theory, a low-power microprocessor, and a tactile feedback mechanism that simulates acupuncture stimulation. The EEG sensor array: the electrodes are arranged in the frontal area (Yintang, Shenting points), temporal area (Taiyang, Zhugu points), and top pillow area (Baihui, Fengchi points), corresponding to the areas stimulated by traditional Chinese medicine acupuncture. Dry electrode technology is used to simultaneously collect bioelectrical signals from multiple brain regions and meridians and acupoints. The electrodermal response module: The measurement site is selected from the Laogong point area on the hand or the heart area reflex point on the ear, and the ear hook integrated flexible electrode and the main body front end conductive rubber electrode form a body surface meridian circuit. The heart rate variability detection unit uses an optical sensor to obtain the forehead pulse wave signal, and the sampling frequency meets the needs of traditional Chinese medicine pulse diagnosis detection. The tactile feedback mechanism includes vibration actuators distributed at the positions corresponding to the acupuncture points such as Tou Wei and Si Shen So, and simulates the sensation of receiving qi through acupuncture and moxibustion with vibration pulses of different frequencies.

[0025] The head-mounted body structure is designed with an adjustable headband based on the traditional Chinese medicine theory of head circumference, the body material is made of biocompatible silicone rubber and an alloy frame, and the electrode contact position is set to conform to the traditional Chinese medicine theory of head positioning. The EEG sensor array contains 8 to 16 electrodes, of which the forehead electrodes correspond to the area where the Du meridian and bladder meridian flow, the temporal electrodes correspond to the area where the Shaoyang meridian is distributed, and the parieto-occipital electrodes correspond to the area where the Taiyang meridian and Du meridian intersect, and are configured to form a signal collection network that is suitable for Chinese medicine head meridian differentiation. Based on the traditional Chinese medicine theory that "the heart governs the gods," the electrodermal response module selects the Shenmen area (wrist), which is the primary acupoint of the heart meridian, or the heart area of ​​the concha cavity as auxiliary measurement points, and combines them with the Renmai acupoint area on the forehead to form a multidimensional emotional arousal detection circuit.

[0026] In addition, the heart rate variability detection unit is configured to extract the photoelectric volume pulse wave signal from the forehead, combine it with the three-element analysis model of "stomach qi, shen qi, and endurance qi" of traditional Chinese medicine pulse diagnosis, and output HRV parameters that reflect the autonomic nervous system balance state. The vibration frequency range of the tactile feedback mechanism covers the alpha wave (8-13Hz) and beta wave (14-30Hz) bands, corresponding to the Chinese medicine adjustment theory of "stillness nourishes the spirit, movement moves the qi," and is designed to stimulate acupoints on the head with a combination of different vibration frequencies to improve cognitive state.

[0027] The microprocessor is equipped with a built-in algorithm for distinguishing Chinese herbal symptoms, and is configured to construct a cognitive fatigue and emotional imbalance symptom model that conforms to the Chinese herbal symptom diagnosis theory based on the EEG delta / theta / alpha / beta wave energy distribution, skin conductance response amplitude, and heart rate variability time domain parameters. The electrode placement within the main structure follows the traditional Chinese holography theory of "left governs the liver, right governs the lungs, and forehead governs the gods," with the left temporal electrode corresponding to the liver meridian reflex zone, the right corresponding to the lung meridian reflex zone, and the central forehead electrode corresponding to the regulating area of ​​the Du meridian Yuanshenzhifu. The vibration intensity of the tactile feedback mechanism is divided into two modes: Toho (low-intensity continuous vibration) and Dashiho (high-intensity intermittent vibration). This corresponds to the Chinese acupuncture principle of regulation: "If there is deficiency, replenish it; if there is fullness, drain it." It is designed to improve cognitive function by stimulating acupoints.

[0028] Operating principle In this embodiment, the operating principle of the AI ​​cognitive coaching biofeedback smart headband is as follows. The EEG sensor array uses dry electrode technology to target bioelectrical signals from the frontal area (Yintang and Shenting points), temporal area (Taiyang and Zhugu points), and topoccipital area (Baihui and Fengchi points). The electrodes are positioned to correspond to the meridian circulation areas of the Du meridian, bladder meridian, and Shaoyang meridian, achieving synchronized acquisition of brain electrical activity and meridian signal. The electrodermal response module selects the Laogong point on the hand (heart meridian Rong point) or the heart meridian reflex point on the ear. The flexible earhook electrodes and the front-end conductive rubber electrodes form a meridian circuit on the body surface, detecting emotional arousal based on the "heart governs the spirits" theory. The heart rate variability detection unit collects pulse waves using a forehead optical sensor, with a sampling frequency that meets the dynamic detection needs of "stomach qi, spirit qi, and endurance qi" in traditional Chinese medicine pulse diagnosis. Combined with the photoplethysmographic signal, HRV parameters are extracted to reflect the autonomic nervous system balance.

[0029] After preprocessing and synchronously integrating the multi-modal signals, the low-power microprocessor uses a built-in traditional Chinese symptom discrimination algorithm to analyze the EEG delta / theta / alpha / beta wave energy distribution (corresponding to the state of the brain), skin conductance response amplitude (corresponding to emotional stress level), and heart rate variability time domain parameters (RR interval, SDNN, etc.). This is combined with the holographic theory that "the left governs the liver, the right governs the lungs, and the forehead governs the spirit" to construct quantitative models for symptoms such as cognitive fatigue and emotional imbalance. For example, if the EEG theta wave energy is elevated and the HRV parameters indicate autonomic nervous system imbalance, the algorithm will identify the symptom as "mental imbalance," providing a basis for subsequent intervention.

[0030] The microprocessor transmits symptom analysis results to the AI ​​cognitive coaching system via a wireless communication module. Based on the theory of "Xingshen Synchoron," the system generates haptic feedback strategies targeting acupuncture points such as the Baihui, Sishensong, and Zhugu acupuncture points. The haptic feedback mechanism uses a vibration actuator to achieve intervention. The vibration frequency covers the alpha wave (8-13 Hz, corresponding to "stillness nourishes the spirit") and beta wave (14-30 Hz, corresponding to "movement moves qi") frequency bands, and the combination of different vibration frequencies regulates brain wave rhythms. The vibration intensity can be controlled in two modes: "supplementing" (low-intensity continuous vibration) and "draining" (high-intensity intermittent vibration), mimicking the acupuncture principle of "replenishing deficiency and draining elimination" to stimulate the acupuncture points on the head and improve cognitive status. The intervention effect is achieved through real-time physiological signal feedback, forming a closed-loop regulation system that continues until the cognitive state optimization goal is reached.

[0031] The head-mounted device features an adjustable headband designed based on traditional Chinese medicine head circumference theory, and a biocompatible silicone rubber and alloy frame ensure a comfortable fit. The electrode contact points are positioned based on head positioning theory, and combined with dry electrode technology, they avoid reliance on conductive gel. This maintains stable signal collection even during long-term wear, providing a reliable data base for physiological signal analysis throughout the entire process.

[0032] The technical scope of the present invention is not limited to the above description, and those skilled in the art may make various modifications and alterations to the above embodiments without departing from the technical idea of ​​the present invention, and all such modifications and alterations shall fall within the scope of protection of the present invention.
