Description

Inflatable garments equipped with piezoelectric elements designed to measure cardiograms

[0001] The present disclosure relates to an inflatable garment designed to care for a psychological state based on biometric information, and more particularly, to an inflatable garment having a sensor module including a piezoelectric element designed to measure ballistic cardiography.

[0002] As the importance of managing and stabilizing a person's psychological state or stress has increased in recent years, the need for methods and devices to relieve anxiety and stress has emerged.

[0003] In this regard, as a method and technology for judging or estimating a user's psychological state or stress, a wearable device equipped with a biometric sensor designed to acquire biometric information acquires the user's biometric information, and a method and technology for judging or estimating the user's psychological state based on the acquired biometric information of the user have been proposed.

[0004] To assess or infer a user's psychological state or stress, biometric data is required. To assess these psychological states or stress more precisely, noise in the biometric data, which serves as the basis for assessing these states or stress, must be minimized. In other words, a method is needed to acquire the user's biometric data in real time while minimizing noise.

[0005] In response to the above-mentioned needs, a method of acquiring a user's biometric information in real time was previously adopted through a sensor in contact with the user's body (i.e., a contact-type biometric sensor). However, the user may experience uncomfortable sensations such as discomfort, a foreign body sensation, or a feeling of restriction due to the contact of the biometric sensor. Accordingly, a method of acquiring a user's biometric information using a non-contact biometric sensor has been proposed as a method of acquiring the user's biometric information without making contact with the user's body.

[0006] However, even when biometric information is acquired using a non-contact biometric sensor, noise caused by the user's body movements, etc., is still greater in the sensing data of the non-contact biometric sensor than in the sensing data of the contact biometric sensor.

[0007] Therefore, there is a need for an air-injected compression garment that can collect the user's biometric information while minimizing noise that may be generated from the user's movements and relieving discomfort by not directly contacting the user's body, such as a non-contact biometric sensor.

[0008] According to one embodiment, a wearable device for caring for a user's psychological state based on the user's biometric information may include an outer shell having a front part positioned on the user's chest area and a rear part positioned on the user's back area. The outer shell may include a first side facing the user's body and a second side facing away from the body. The wearable device may include an air tube positioned between the first side and the second side, an air inlet provided at one end of the air tube so that air is injected into or extracted from the air tube, a driving unit for injecting or extracting air into or from the air tube through the air inlet, a silicone tube extending from the driving unit and connected to the air inlet, a sensor module positioned inside the silicone tube and having a piezoelectric element for detecting pressure, and a processor positioned inside the silicone tube and operatively connected to the driving unit and the sensor module.

[0009] According to one embodiment, the processor obtains air pressure data representing the air pressure inside the air tube through the piezoelectric element of the sensor module, and determines the user's condition based on the air pressure data, wherein the user's condition may include at least one of the user's psychological condition, stress level, or type of physical symptom. Based on the determined user's condition, the driving unit may be controlled to inject air into the air tube.

[0010] According to one embodiment of the present disclosure, an inflatable garment equipped with a bio-module including a piezoelectric element can determine a user's psychological state or stress, and non-intrusively collect bio-information necessary for caring for the same, without contacting the user's skin. Furthermore, based on air pressure data measured through a piezoelectric element located inside a sealed silicone tube, the user's cardiogram can be measured, and by acquiring the user's bio-information based on the measured air pressure data, noise included in the bio-information can be reduced compared to when the bio-information is acquired using a conventional non-contact bio-sensor. In other words, the user's psychological state or stress can be more precisely determined using the bio-information with reduced noise, and by applying air pressure to the user based on the determined air pressure, the user's anxiety or stress can be effectively reduced.

Furthermore, when a part is said to "include" a component, this should be understood to mean that, unless specifically stated to the contrary, it may include other components rather than excluding them, and does not preclude the presence or addition of one or more other features, numbers, steps, operations, components, parts, or combinations thereof.

[0026] FIG. 1 illustrates a system for caring for a user's psychological state using a wearable device (101) according to one embodiment.

[0027] Referring to FIG. 1, a system for managing a user's psychological state may include a wearable device (101), a network (102), and a server (103). However, the system is not limited to the components illustrated in FIG. 1, and some components may be omitted or added. For example, the system may further include a user terminal (e.g., a smartphone).

[0028] According to one embodiment, the wearable device (101) may be referred to as an air-injected garment including an air tube (e.g., the air tube (110) of FIG. 2), an air inlet (e.g., the air inlet (204) of FIG. 2), and a driving unit to provide deep touch pressure (DTP) to a user wearing the wearable device (101). For example, the wearable device (101) may refer to an air-injected garment designed to provide deep touch pressure to a user wearing the wearable device (101) so as to relieve psychological anxiety and reduce stress by the user feeling psychologically anxious or under high stress when the user wears the wearable device (101). Here, deep touch pressure refers to pressure that stimulates the parasympathetic nerve by applying appropriate pressure to the user's body, thereby allowing the user to feel as if someone is hugging him / her, thereby relieving anxiety or reducing stress and providing a sense of psychological stability. The above users may include individuals who require psychological stability or who seek relief from stress (e.g., children or individuals with developmental disabilities). However, the above users are not limited to the examples described above, and may include infants, toddlers, children, adolescents, people with disabilities, or the elderly.

[0029] According to one embodiment, the driving unit may function as an air pump, and may inject air into the air tube (e.g., the air tube (110) of FIG. 2) through the air inlet (e.g., the air inlet (204) of FIG. 2) or extract air from the air tube. For example, when it is determined that a user wearing the wearable device (101) feels anxious or stressed, the driving unit may inject air into the air tube through the air inlet. After air is injected into the air tube, when it is determined that the user's anxiety or stress has been relieved, the driving unit may extract air from the air tube. The criterion for determining that the user feels anxious or stressed may be determined based on the user's biometric information acquired through a sensor module (e.g., the sensor module (201)) provided in the wearable device (101). For example, if a value included in the biometric information exceeds a set value and / or a set range, the wearable device (101) may determine that the user is anxious or stressed.

[0030] According to one embodiment, the wearable device (101) may include a communication module capable of performing data communication with an external electronic device. For example, the wearable device (101) may perform data communication with a server (103) via a network (102).

[0031] According to one embodiment, the wearable device (101) may transmit biometric information (e.g., ballistic cardiogram information, heart rate variability information, or respiration information) acquired using a sensor module (e.g., sensor module (201) of FIG. 2) provided in the wearable device (101) to a server (103) via a network (102). The wearable device (101) may receive an artificial intelligence model updated by the server (103) from the server (103).

[0032] According to one embodiment, the server (103) can perform data communication with the wearable device (101) and drive an artificial intelligence model to produce data values ​​for controlling the driving unit of the wearable device (101). For example, the server (103) can train an artificial intelligence model using learning data and obtain output data by inputting input data into the artificial intelligence model.

[0033] According to one embodiment, when data communication is established with the wearable device (101), the server (103) can receive the user's biometric information from the wearable device (101). When data communication is established with the wearable device (101), the server (103) can transmit an updated artificial intelligence model to the wearable device (101).

[0034] According to one embodiment, although not shown in FIG. 1, the wearable device (101) can perform data communication with a user terminal (e.g., a smart phone) via a network (102). For example, the wearable device (101) can transmit biometric information acquired through a sensor module (e.g., a sensor module (201) of FIG. 2) provided in the wearable device (101) to the user terminal. The user terminal can transmit command data for controlling the wearable device (101) to the wearable device (101) via the network (102).

The first artificial intelligence model (408-1) may refer to an artificial intelligence model used to process (or preprocess) air pressure data or biosignals (e.g., BCG signals) acquired through the piezoelectric element (402). That is, the first artificial intelligence model (408-1) may refer to an artificial intelligence model that performs a raw data filter to extract filtered data (filtered signals) from raw data processed (e.g., Fourier transform and wavelet transform) using a template matching technique. The first artificial intelligence model (408-1) may be referred to as a similar signal matching model as an artificial intelligence model that utilizes a template matching technique. The above raw data may refer to air pressure data obtained through a piezoelectric element (402) or data that has been preprocessed through a data processing unit (409). The above preprocessing may refer to Fourier transform and wavelet transform.

[0060] According to one embodiment, the first artificial intelligence model (408-1) may be trained to output filtered data when raw data is input by utilizing a normal BCG data set (or a normal biometric data set).

[0069] According to one embodiment, the heart disease-related symptoms, such as heart failure, arrhythmia, and myocardial infarction, which affect heart health, can reduce the variability of heart rate variability.

[0070] According to one embodiment, the data processing unit (409) may be a circuit that processes sensing data (e.g., BCG raw data) acquired through a sensor (e.g., a piezoelectric element (402) of a sensor module (201)) into input data to be input into an artificial intelligence model (e.g., a first artificial intelligence model (408-1)). For example, the data processing unit (409) may perform a preprocessing operation to process air pressure data representing air pressure in an air tube (110) of a wearable device (101) acquired through a piezoelectric element (402) into input data to be input into the first artificial intelligence model unit (408-1) of the artificial intelligence model unit (408). The preprocessing process may mean a Fourier transform and a wavelet transform. The data processing unit (409) can first apply Fourier transform to the air pressure data acquired through the piezoelectric element (402) and secondarily apply wavelet transform to generate transformed data. Data obtained by applying the Fourier transform to the raw data may be first transformed data, and data obtained by applying the wavelet transform to the first transformed data may be second transformed data.

[0071] According to one embodiment, the noise removal unit (410) can remove noise included in sensing data detected through the piezoelectric element (402) based on movement data acquired from a motion sensor (407) (e.g., a 3-axis motion sensor, an acceleration sensor, a geomagnetic sensor, and / or a gyro sensor). For example, the noise removal unit (410) can remove noise data included in the sensing data by superimposing signals of the x, y, and z axes measured from an acceleration sensor on sensing data (e.g., air pressure data) measured through the piezoelectric element (402) and removing the amplified signals.

[0072] According to one embodiment, the battery (411) may supply power to operate the sensor module (201). The battery (411) may be capable of being charged by wires and / or wirelessly.

[0080] According to one embodiment, when a user wearing a wearable device (101) exhales or his / her heart contracts (601), the user's blood vessels may maintain their original state or become dilated. When a user wearing a wearable device (101) inhales or his / her heart contracts (602), the user's blood vessels may become contracted compared to their original state.

[0081] According to one embodiment, the wearable device (101) can obtain the user's biometric information through the sensor module (201). The wearable device (101) can obtain raw data (611) representing the user's biometric information through the sensor module (201). The wearable device (101) can process the raw data through the data processing unit (409) to generate ballistic cardiogram (BCG) data (612) and respiration data (613).

[0087] FIG. 8 illustrates a flowchart of a method for a wearable device (101) to care for a psychological state using biometric information according to one embodiment.

[0088] The operations of the wearable device (101) described below may be performed in different order or simultaneously.

[0089] In operation 801, the wearable device (101) can obtain biometric information of a user wearing the wearable device (101) in real time through the sensor module (201). For example, the wearable device (101) can detect air pressure within an air tube (110) of the wearable device (101) through the piezoelectric element (402) of the sensor module (201), thereby obtaining air pressure data. The air pressure may vary depending on the user's heartbeat or breathing state.

[0090] According to one embodiment, the wearable device (101) can process the air pressure data into biometric data through the data processing unit (409) and the artificial intelligence model unit (408). The air pressure data can be understood as raw data or ballistic cardiogram data. The wearable device (101) can process the raw data through the data processing unit (409). For example, the wearable device (101) can first apply a Fourier transform to the raw data through the data processing unit (409) and secondarily apply a wavelet transform to the raw data.

[0091] According to one embodiment, the wearable device (101) can obtain ballistic cardiogram data and respiratory data by applying puree transformation and wavelet transformation to the raw data. The ballistic cardiogram data and the respiratory data may refer to the second transformed data.

[0092] According to one embodiment, the wearable device (101) may perform a Fourier transform by separating a first frequency corresponding to a heart rhythm to obtain ballistic cardiogram data (or second transformed data) from the raw data. The wearable device (101) may perform a wavelet transform using a wavelet function modeled according to a heart rhythm on the first transformed data obtained by performing the Fourier transform.

[0093] According to one embodiment, the wearable device (101) may perform a Fourier transform by separating a second frequency corresponding to a respiratory rhythm to obtain respiratory data (or second transformed data) from the raw data. The wearable device (101) may perform a wavelet transform using a wavelet function modeled according to the respiratory rhythm on the second transformed data obtained by performing the Fourier transform.

[0094] According to one embodiment, the wearable device (101) inputs the second transformed data to which the Fourier transform and wavelet transform are applied into the first artificial intelligence model (408-1) of the artificial intelligence model unit (408), and based on the output data, acquires biometric data in real time. The biometric data is data to which the template matching technique of the first artificial intelligence model is applied, and may be referred to as data to which a raw data filter is applied. The biometric data may include ballistic cardiogram data or respiratory data to which the raw data filter is applied.

[0095] In operation 802, the wearable device (101) can detect an abnormal condition of a user wearing the wearable device (101) based on biometric data acquired in real time (e.g., ballistic cardiogram data or respiration data) or data processed from the biometric data (e.g., heart rate data or heart rate variability data). For example, the wearable device (101) can detect an abnormal condition of the user based on whether a numerical value of the biometric data exceeds a specified range.

[0096] According to one embodiment, the wearable device (101) can detect an abnormal state of the user based on whether the heart rate data exceeds a specified range. The specified range may be a first value or a second value, and the specified range may mean a normal heart rate range by age. For example, since the normal average heart rate for adults aged 20 or older is approximately 70 to 75 beats per minute, the first value may be 70 beats per minute, and the second value may be 75 beats per minute. However, the present invention is not limited to the above-described values. If the heart rate data exceeds the specified range, the wearable device (101) may determine that the user is feeling anxious or stressed.

[0097] According to one embodiment, the wearable device (101) can detect an abnormal state of the user based on whether the heart rate variability data exceeds a specified range. The specified range may be a third value or a fourth value, and the specified range may refer to a normal heart rate variability range by age. For example, when the psychological state is stable or the stress level is low, the heart rate variability may be high, in which case the difference value between the third value and the fourth value, which is a specified range, may be a first difference value. When the psychological state is unstable or the stress level is high, the heart rate variability may be low, in which case the difference value between the third value and the fourth value, which is a specified range, may be a second difference value. The first difference value may be greater than the second difference value. When the heart rate variability data exceeds a specified range, the wearable device (101) may determine that the user is feeling anxious or stressed.

[0098] According to one embodiment, the wearable device (101) can detect an abnormal state of the user based on whether the breathing data exceeds a specified range. The specified range may be a fifth value or a sixth value, and the specified range may refer to a normal breathing rate range. The fifth value may be 12 breaths per minute, and the sixth value may be 20 breaths per minute. If the breathing data exceeds the specified range, the wearable device (101) can determine that the user is feeling anxious or stressed.

[0099] In operation 803, when the wearable device (101) detects that the user is feeling anxious or stressed, i.e., is in an abnormal state, the wearable device (101) may automatically control the driving unit to inject air into the air tube (110) of the wearable device (101). The wearable device (101) may transmit at least one of status information indicating that the user is in an abnormal state or information related to controlling the driving unit to an external device (e.g., a server (103) or a user terminal).

[0100] According to one embodiment, the wearable device (101) can determine at least one of the type of the user's psychological state, the level of stress, or the type of symptom based on the user's biometric information.

[0101] In one embodiment, the types of psychological states may include anger, sadness, joy, comfort, anxiety, etc. The stress level may be divided into intervals and categorized into predetermined stages. For example, the stress level may be categorized from Level 1 to Level 5, and it may be understood that stress increases from Level 1 to Level 5. The types of symptoms may include stress-related symptoms, respiratory symptoms, pain-related symptoms, depression-related symptoms, and heart disease-related symptoms.

[0102] According to one embodiment, the wearable device (101) may select an air injection method corresponding to the type of the user's psychological state, the level of stress, and the type of symptom determined above. The air injection method may include at least one of air injection strength, air injection speed, maintenance time after air injection, or air compression area. The wearable device (101) may control the driving unit of the wearable device (101) to inject air into the air tube (110) based on the selected air injection method. For example, when the user's psychological state is determined to be anxious, the wearable device (101) may inject air into the air tube (110) at a first pressure and a first speed, and maintain the air injection state for a first duration. For another example, if the user's psychological state is determined to be angry, the wearable device (101) may inject air into the air tube (110) at a second pressure greater than the first pressure and at a second speed faster than the first speed, and maintain the air injection state for a second duration longer than the first duration. The air injection method is not limited to the above example.

[0103] In operation 804, the wearable device (101) can detect that the user's psychological state is stable based on the user's biometric information acquired in real time. For example, the wearable device (101) can determine that the user's psychological state is stable if the numerical value of the user's biometric data falls within a specified range. For example, the wearable device (101) can determine that the user's psychological state is stable if at least one of the ballistic cardiogram data, heart rate data, heart rate variability data, or respiration data falls within a specified range.

[0104] According to one embodiment, when the user's psychological state is determined to be stable, the wearable device (101) may control the driving unit of the wearable device (101) to extract air from the air tube (110). The wearable device (101) may transmit at least one of state information indicating that the user's psychological state is stable or information related to controlling the driving unit to an external device (e.g., a server (103) or a user terminal).

[0105] FIG. 9 illustrates a flowchart of operations between a wearable device (101) and a server (103) for caring for a psychological state using biometric information according to one embodiment.

[0106] The operations of the wearable device (101) and the server (103) described below may be performed in different order or simultaneously.

[0107] In operation 901, the wearable device (101) can acquire biometric data through a sensor (e.g., a sensor module (201)) provided in the wearable device (101). The biometric data may include at least one of ballistic cardiogram data, heart rate data, heart rate variability data, respiration data, skin conductance data, photoplethysmography data, pulse data, or thermal data. The biometric data may refer to data processed from raw data (or pressure data or air pressure data) detected through a piezoelectric element (402) of the sensor module (201) of the wearable device (101).

[0108] According to one embodiment, the wearable device (101) can obtain air pressure data (or pressure data or raw data) representing the air pressure within the air tube (110) of the wearable device (101) through the piezoelectric element (402) of the sensor module (201).

[0109] In operation 902, the wearable device (101) may store the biometric data in the data storage unit (405). The wearable device (101) may perform an operation of removing noise included in the biometric data through the noise removing unit (410). According to one embodiment, the wearable device (101) may remove noise included in the sensing data (e.g., pressure data, air pressure data) detected through the piezoelectric element (402) through the noise removing unit (410). For example, the wearable device (101) may remove noise in the sensing data by overlapping the sensing data with movement data detected through the motion sensor (407) and removing an amplified signal. The movement data may include x, y, and z-axis data of an acceleration sensor.

[0110] In operation 903, the wearable device (101) may transmit the biometric data to the server (103) via the communication unit (406). Although not illustrated in FIG. 9, the wearable device (101) may transmit not only the biometric data, but also at least one of raw data, preprocessed data of the raw data (e.g., first converted data, second converted data), and filtered data processed using the first artificial intelligence model to the server (103). The raw data may refer to pressure data or air pressure data. In order for the wearable device (101) to transmit the biometric data to the server (103) via the communication unit (406), it may be assumed that the sensor module (201) or the driving unit of the wearable device (101) is in a charged state. For example, only when the sensor module (201) or driving unit of the wearable device (101) is in a charged state, the wearable device (101) can perform data communication with the server (103) through the communication unit (406).

[0111] According to one embodiment, the wearable device (101) may transmit the user's personal information (e.g., age, gender, height, weight, degree of disability, etc.) to the server (103) through the communication unit (406).

[0112] In operation 904, the server (103) can store biometric data and personal information received from the wearable device (101) in a database.

The third artificial intelligence model may be learned and operated in substantially the same manner as the first artificial intelligence model (408-1). The third artificial intelligence model may be referred to as a signal matching model as an artificial intelligence model that utilizes a template matching technique. For example, the third artificial intelligence model may be learned to output filtered data when raw data is input using a normal BCG data set (or a normal biometric data set).

[0115] According to one embodiment, the server (103) may extract features from raw data received from a wearable device (101), and then perform vector quantization to generate a template (or template data) for utilizing a template matching technique.

[0116] According to one embodiment, the server (103) may learn and operate a fourth artificial intelligence model that uses the user's personal information and biometric information to determine the user's psychological state, stress level, and type of symptom. The fourth artificial intelligence model may be learned and operated in substantially the same manner as the second artificial intelligence model (408-2). The fourth artificial intelligence model may be referred to as a personalized learning model as an artificial intelligence model used to classify the user's symptoms. For example, the fourth artificial intelligence model may be trained to output the type of symptom when inputting data (e.g., heart rate variability data, respiration data) processed from data (e.g., ballistic cardiogram data) output from the third artificial intelligence model.

[0117] In operation 906, the server (103) can transmit the generated template (or template data) to the wearable device (101). The server (103) can update the learned artificial intelligence model (e.g., the third artificial intelligence model and the fourth artificial intelligence model) using the data (e.g., raw data, biometric data, etc.) received from the wearable device (101), and transmit the updated artificial intelligence model to the wearable device (101).

[0118] In operation 907, operation 907 may be substantially the same as operation 802. The wearable device (101) may detect an abnormal state of the user by utilizing the updated artificial intelligence model received from the server (103). The wearable device (101) inputs preprocessed raw data (e.g., second transformed data) into the updated first artificial intelligence model (408-1), outputs filtered data, processes the filtered data, inputs it into the updated second artificial intelligence model (408-2), and determines whether the user's state is abnormal based on the output value.

[0119] In operation 908, operation 908 may be substantially the same as operation 803. In response to detecting that the user's condition is abnormal, the wearable device (101) may automatically inject air into the air tube (110) and transmit the user's current condition to an external device (e.g., a server (103) or a user terminal).
