Description

Technical Field

[0001] This utility model relates to the field of smart wearable technology, specifically to a smart garment based on adaptive fit and flexible partitioning. Background Technology

[0002] When collecting physiological motion signals such as heart rate, respiration, and posture, existing smart clothing requires sensors to maintain stable contact with the skin. The sensor groups in existing smart clothing are usually directly mounted on the clothing, causing the sensor groups to come into direct contact with the user's skin. Users may experience a foreign body sensation due to the sensors. During exercise, prolonged contact between the user's skin and hard objects such as sensors can easily cause friction injuries to the skin surface, affecting the user experience. Utility Model Content

[0003] The purpose of this invention is to provide a smart garment that aims to reduce the discomfort caused by the sensor array when wearing it by improving the garment structure.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A smart garment includes a garment body and a sensor group. The garment body includes an outer layer, a sensing layer and a skin-friendly layer from the outside to the inside. The sensing layer includes a sensing area, a transition area and a blank area. The sensor group is disposed in the sensing area. The transition area is woven between the sensing area and the blank area. The thickness of the transition area decreases from the edge of the sensing area to the edge of the blank area.

[0006] Furthermore, the sensing area is made of highly elastic, skin-friendly fiber fabric, and the blank area is made of breathable, lightweight yarn fabric.

[0007] Furthermore, the antibacterial rate of the skin-friendly layer is ≥99%, and the moisture permeability of the outer layer, sensing layer, and skin-friendly layer corresponding to the sensing area is ≥5000g / m². 2 ·24h.

[0008] Furthermore, the sensing area includes a connection area, and the sensor group is converged to the connection area via conductive yarn, with the main control module connected to the connection area.

[0009] Furthermore, the conductive yarn is laid in a serpentine / spiral pattern.

[0010] Furthermore, the sensor group includes a flexible textile electrode, a flexible pressure sensor, and an airbag. The flexible textile electrode is located in the chest area inside the sensing layer, the flexible pressure sensor is located in the chest area of ​​the garment body, and the airbag is located in the sensing layer corresponding to the flexible textile electrode. The main control module controls the inflation amount of the airbag and receives the heart rate information collected by the flexible textile electrode.

[0011] Furthermore, the airbag is arranged in a ring on the flexible textile electrode, and the airbag is located within the step provided in the transition zone.

[0012] Furthermore, the skin-friendly layer is provided with a clearance area corresponding to the flexible textile electrode.

[0013] Furthermore, the sensor group also includes a yarn sensing strip, which is disposed at the chest and abdomen positions of the garment body.

[0014] Furthermore, the sensor group also includes an IMU module, which includes IMU units fixed to the scapular region, the two sides of the chest cavity, and the two sides of the waist of the smart garment, respectively, for collecting the user's posture information.

[0015] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:

[0016] 1. This utility model improves wearing comfort while protecting the sensing layer through a three-layer composite structure. At the same time, the independent setting of the sensing area ensures the stability of the centralized arrangement of the sensor group. The blank area adopts a non-sensing area to avoid the feeling of restraint caused by redundant materials. The transition area achieves a flexible connection between the sensing area and the blank area through the change of thickness gradient. The physical characteristics of decreasing thickness not only ensure the support strength of the sensor edge area, but also avoid the pressure marks caused by hard boundaries on the skin.

[0017] 2. This utility model, by limiting the high antibacterial properties of the skin-friendly layer, inhibits the damage of bacteria to the skin during long-term wear, meeting the need for smart clothing to be washed less frequently than ordinary clothing; at the same time, by controlling the amount of moisture permeable to the outer layer, sensing layer and skin-friendly layer in the sensing area, it avoids the accumulation of sweat affecting the impedance of the sensor and improves the detection accuracy.

[0018] 3. This invention achieves dual optimization of function and comfort through differentiated material selection for different zones. High-elasticity, skin-friendly fibers are used in the sensing area that directly supports the sensor, utilizing their high resilience to ensure a continuous and close fit between the sensor and the skin, preventing sensor displacement due to fabric deformation during movement. Simultaneously, breathable, lightweight yarns are used in the non-sensing areas, improving airflow efficiency by reducing fabric density and increasing pore structure, effectively alleviating the stuffiness and restrictive feeling caused by the extensive use of elastic materials in traditional smart clothing.

[0019] 4. The conductive yarn of this utility model is laid in a serpentine / spiral pattern, which takes into account both the stretchability required by clothing and the stability required by electrical circuitry.

[0020] 5. This utility model adjusts the fit of the flexible electrode by changing the inflation volume of the airbag. The main control module receives pressure data and controls the inflation volume of the airbag, forming a closed-loop control mechanism of pressure sensing-airbag adjustment-signal optimization, which ensures the quality of heart rate signal acquisition while maintaining wearing comfort.

[0021] 6. This invention adjusts the airbag pressure according to the user's movement state to balance the accuracy of data collection and the user's comfort.

[0022] 7. The avoidance area set in the skin-friendly layer of this utility model greatly improves the contact area between the sensor and the skin, reduces the discomfort of wearing, and improves the user's wearing experience.

[0023] 8. This invention is equipped with a yarn sensing belt, which can collect user physiological data information from multiple dimensions.

[0024] 9. This invention improves safety by using a temperature sensor to determine whether there is prolonged overpressure. Attached Figure Description

[0037] Example

[0038] Please refer to Figures 1 to 4 As shown, this embodiment provides a smart garment. The garment body 100 includes an outer layer 110, a sensing layer 120, and a skin-friendly layer 130 from the outside to the inside. The sensing layer 120 includes a sensing area 1261, a transition area 1262, and a blank area 1263. The sensor group is disposed in the sensing area 1261. The transition area 1262 is woven between the sensing area 1261 and the blank area 1263, and its thickness decreases from the edge of the sensing area 1261 to the edge of the blank area 1263.

[0039] Please refer to Figure 3 As shown, specifically, the sensing layer 120 refers to the intermediate layer where the sensor assembly is located. This can be achieved using a knitted spacer fabric, whose three-dimensional structure provides a fixed space for the sensor while maintaining the fabric's elasticity. The outer layer 110 and the skin-friendly layer 130 encapsulate the sensing layer 120, making the sensor module invisible. This eliminates the foreign object sensation associated with traditional rigid devices, resulting in a neater appearance for the garment and also protecting the sensor to some extent, thus extending its lifespan.

[0040] The sensing area 1261 is woven with highly elastic fibers 140 to form a rigid support structure, ensuring stable contact between the sensor assembly and the skin. The transition area 1262, through a gradient change in yarn density, creates a decreasing thickness, forming a flexible transition between the edge of the sensing area 1261 and the blank area 1263. When the garment body 100 is stretched by an external force, the thickness gradient change in the transition area 1262 can evenly transfer stress from the sensing area 1261 to the blank area 1263, avoiding skin indentations caused by sudden changes in local stress, thus improving overall wearing comfort while ensuring signal acquisition accuracy.

[0041] In a preferred embodiment, the sensing area 1261 is made of highly elastic, skin-friendly fiber, and the blank area 1263 is made of breathable, lightweight yarn.

[0042] High-elasticity, skin-friendly fibers refer to textile materials with high resilience and a skin-friendly surface, such as spandex composite yarns or polyester elastic fiber 140, with an elastic modulus ranging from 0.5 to 5 GPa. These fibers maintain stable contact pressure between the sensor and the skin through elastic deformation. Breathable, lightweight yarns refer to low-density textile materials with high porosity, specifically honeycomb-structured nylon yarns or ultra-fine denier polyester yarns, with a porosity of 30% to 60%, reducing stuffiness by increasing airflow.

[0043] In a preferred embodiment, the antibacterial rate of the skin-friendly layer 130 is ≥99%, and the moisture permeability of the outer layer 110, the sensing layer 120, and the skin-friendly layer 130 corresponding to the sensing area 1261 is ≥5000g / m². 2 ·24h.

[0044] Specifically, the skin-friendly layer 130 uses a TPU nanofiber membrane composite antibacterial fabric. This involves electrospinning thermoplastic polyurethane material into a nanofiber structure and then combining it with an antibacterial agent. The antibacterial agent can be achieved through silver ion loading or quaternary ammonium salt grafting. While utilizing the nanoscale porous structure to achieve breathability, the slow-release effect of the antibacterial components inhibits bacterial growth that might occur when smart clothing is washed less frequently than ordinary clothing, thus maintaining hygienic conditions for wearers.

[0045] Moisture permeability refers to the mass of water vapor that passes through a unit area of ​​fabric in 24 hours. It can be achieved by controlling the porosity of the fabric. For example, a gradient density weaving process can be used to balance breathability and structural strength. Rapid moisture wicking prevents the sensing area from becoming stuffy and sweaty, effectively preventing sensor impedance abnormalities caused by sweat accumulation, and improving the accuracy of data acquisition.

[0046] In a preferred embodiment, the sensing area 1261 includes a connection area 125, and the sensor group is converged to the connection area 125 by conductive yarn 124. The main control module 200 is connected to the connection area 125 by magnetic attraction or snap-fit.

[0047] The conductive yarn 124 refers to a flexible wire used for transmitting electrical signals, such as silver-plated fiber or carbon fiber composite yarn. It can adapt to garment stretching through bending deformation, avoiding signal transmission failure due to the breakage of rigid wires. Magnetic or snap-fit ​​connection refers to the detachable interface between the main control module 200 and the garment body 100, for example, using neodymium iron boron magnets for alignment and attraction or plastic snap-fit ​​mechanical locking, enabling rapid separation while ensuring stable electrical contact.

[0048] Thus, the physiological signals collected by the flexible IMU module 121, flexible textile electrode 122, and yarn sensing strip 123 are transmitted to the connection area 125 via conductive yarn 124. This connection area 125 serves as a signal concentration node embedded in the garment body 100. The main control module 200 forms a physical connection with this connection point via magnetic attraction or snap-fit, thereby establishing an electrical signal path. When it is necessary to clean the garment or replace the main control module 200, it can be directly detached from the connection area 125 by external force.

[0049] Please refer to Figure 2 As shown, in this invention, the conductive yarn 124 is arranged in a serpentine / spiral pattern. Serpentine routing refers to the conductive yarn 124 being arranged in a continuously curved, wavy path, while spiral routing refers to the conductive yarn 124 being arranged in a spiral trajectory around the axis. Through this routing method, when human movement causes the fabric to stretch or twist, the conductive yarn 124 absorbs stress through geometric deformation, avoiding the limitation of rigid wires on the elasticity of the clothing and preventing the conductive path from breaking due to fabric deformation.

[0050] Please refer to Figure 4 As shown, in a preferred embodiment, the sensor group includes a flexible textile electrode 122, a flexible pressure sensor 127, and an airbag 129. The flexible textile electrode 122 is disposed on the chest area inside the sensing layer 120 to collect the user's heart rate information. The flexible pressure sensor 127 is disposed on the chest area of ​​the garment body 100 to monitor the contact pressure between the flexible textile electrode 122 and the user. The airbag 129 is disposed on the sensing layer 120 corresponding to the flexible textile electrode 122. The main control module 200 controls the inflation amount of the airbag 129 and receives the heart rate information collected by the flexible textile electrode 122.

[0051] The main control module 200 is electrically connected to the flexible textile electrode 122, the flexible pressure sensor 127 and the airbag 129 respectively, and adjusts the inflation volume of the airbag 129 according to the contact pressure.

[0052] The airbag 129 is an inflatable microbag that automatically fills with a small amount of gas or gel after being worn, so that the surface of the flexible textile electrode 122 is in close contact with the skin without causing pressure.

[0053] The flexible textile electrode 122 refers to a conductive fabric woven from silver-plated fibers, forming an electrode array using plain weave and other processes. It collects the user's heart rate information via ECG (electrocardiogram) signal acquisition. The main control module 200 is a microcontroller with multi-channel signal processing capabilities, specifically employing a Bluetooth Low Energy chip for wireless data transmission and aligning multi-source sensor data via timestamps. The sensor components are existing technology devices and will not be described in detail in this invention.

[0054] Please refer to Figure 4 As shown, in a preferred embodiment, the airbag 129 is arranged in a ring on the flexible textile electrode, and the airbag 129 is located within the step provided in the transition region 1262.

[0055] The inner ring of the transition zone 1262 extends with a step, and the airbag 129 is locked in the step of the transition zone 1262. The step limits the airbag 129, so that the airbag 129 is blocked from expanding upward when it inflates.

[0056] The airbag 129 can also be sewn onto the sensing area to improve the stability of the airbag after installation.

[0057] The annular airbags 129 are evenly distributed in the sensing area. The top of the airbags contacts the top of the steps in the transition area 1262. When the airbags 129 are inflated, the top of the airbags 129 is blocked from moving upward. At this time, the airbags will move downward, which will push the flexible textile electrode 122 below to move downward. After the annular airbags 129 are inflated, they will push the flexible textile electrode 122 to fit more tightly with the user's skin, making heart rate monitoring, pressure monitoring, and temperature monitoring more stable and accurate, thereby obtaining good and stable detection data. The annular airbags 129 further improve the fit between the flexible textile electrode 122 and the skin.

[0058] The ring-shaped airbag 129 is set to follow the contour of the flexible textile electrode 122, so that after the airbag 129 expands, it pushes the flexible textile electrode 122 more evenly to the user's skin. The flexible textile electrode 122 is evenly stressed, and the pressure on the skin is evenly distributed, reducing the pressure felt by the user's skin after the airbag expands, improving the user experience and reducing discomfort.

[0059] The airbag 129 is connected to the air pump in the main control module 200 via an air tube. The main control module 200 supplies air to the airbag 129 according to the inflation requirements. The air pump is a prior art device and will not be described in detail in this utility model.

[0060] Specifically, the flexible textile electrode 122 is positioned in the chest area, forming stable contact with the skin via conductive yarn 124 to acquire electrocardiogram (ECG) signals. A flexible pressure sensor 127 is integrated with the electrode in the same area, detecting the pressure distribution at the contact interface in real time. When the detected pressure is below a set threshold, the main control module 200 activates an air pump to inflate the airbag, pushing the electrode towards the skin to increase contact force; when the pressure exceeds the set threshold, the airbag deflates to reduce its volume and alleviate pressure. This forms a closed-loop control system of pressure sensing, signal analysis, and airbag adjustment, dynamically maintaining the contact pressure within a suitable range, balancing signal acquisition accuracy with wearable comfort, and is particularly suitable for continuous and stable monitoring of physiological data during exercise.

[0061] Please refer to Figure 3 As shown, in a preferred embodiment, the skin-friendly layer 130 is provided with a clearance area 1264 corresponding to the flexible textile electrode 122. The clearance area 1264 provides clearance space for the flexible textile electrode. The flexible textile electrode 122 contacts the skin through the window opened in the clearance area 1264, thereby improving the detection accuracy.

[0062] The window in the avoidance area 1264 can be opened in different sizes according to the setting requirements of the flexible textile electrode 122, so that the exposed area of ​​the flexible textile electrode 122 is controllable. The flexible textile electrode 122 can be applied to different fabric materials and can be set in a way such as embedded or external by cooperating with the avoidance area 1264, which further improves the user experience of clothing with flexible textile electrodes 122.

[0063] Please refer to Figure 2 As shown, in a preferred embodiment, the sensor group further includes a yarn sensing strip 123, which is disposed at the chest and abdomen positions of the garment body 100. The yarn sensing strip 123 refers to a strain sensor composed of conductive fibers wrapped with elastic yarn. For example, if a spiral winding structure design is adopted, it calculates the breathing frequency and depth by detecting the expansion amplitude of the chest and abdomen, thereby providing the main control module 200 with the user's breathing information.

[0064] The yarn sensing strip 123 is attached to the garment body 100. The yarn sensing strip 123 located at the chest area can contact the sensor group. The elastic yarn sensing strip 123 pulls the sensor group towards the human body, so that the sensor group is attached to the user's skin, and further makes the flexible textile electrode 122 fit more tightly to the user's skin.

[0065] Please refer to Figure 2As shown, in a preferred embodiment, the sensor group further includes an IMU module 121, which is used to collect the user's posture information. The main control module 200 determines the user's current state based on the posture information. When the current state is a stationary state, the judgment threshold for maintaining contact pressure is a basic threshold. When the current state is a moving state, the judgment threshold is increased according to the intensity of the movement. When the contact pressure exceeds the maximum threshold, the judgment threshold is adjusted to the basic threshold.

[0066] The flexible IMU module 121 refers to an inertial measurement unit based on a flexible circuit board, such as an accelerometer and gyroscope integrated on a polyimide substrate. Its flexibility allows it to conform to the curves of the human body without affecting limb movement, while simultaneously collecting acceleration and angular velocity information of the mounting part to obtain attitude information. The judgment threshold refers to the critical pressure value that triggers the inflation adjustment of the airbag 129. The maximum threshold refers to the preset safe upper limit of the airbag 129 inflation volume to avoid causing discomfort to the user.

[0067] In a static state, the main control module 200 maintains a baseline threshold, allowing the flexible textile electrode 122 to collect heart rate signals with minimal contact pressure, avoiding prolonged skin compression. When movement is detected, the main control module 200 calculates the exercise intensity level based on the acceleration amplitude, such as low-intensity walking or high-intensity running, and correspondingly increases the judgment threshold to ensure that the contact pressure between the sensor and the skin is sufficient to resist movement interference during exercise. If the contact pressure reaches the maximum threshold due to over-inflation of the airbag, the main control module 200 immediately resets the judgment threshold to the baseline threshold to prevent discomfort caused by continuous pressure increases.

[0068] The flexible IMU module 121 in this invention is a distributed module, comprising IMU units respectively fixed to the scapular region, the lateral chest region, and the lateral waist region of the smart garment. This optimized IMU layout allows for flexible monitoring of differences between the two sides (such as the periodic swaying of the scapula), monitoring of key force points (such as the waist), and coordinated information from the scapula, the lateral chest region, and the waist region to identify the user's upper body state. Thus, even when only the upper body is covered by the smart garment, the user's state can be accurately monitored.

[0069] Please refer to Figure 4 As shown, in a more preferred embodiment, the sensor group further includes a temperature sensor 128, which is located in the chest area to collect the user's body temperature. When the body temperature is higher than a preset value, the judgment threshold is adjusted to a base threshold. If the body temperature is still higher than the preset value after a certain period of time, an alarm is output.

[0070] The temperature sensor 128 is a detection device used to monitor the user's body surface temperature in real time. It can be implemented using a flexible thermocouple or a thermistor, integrated into the chest area of ​​the clothing to be close to the skin. The preset value is a trigger threshold set according to the normal human body temperature range, for example, 37.5℃. The base threshold is the initial reference value for adjusting the airbag pressure, used to avoid excessive compression due to abnormal temperature. The alarm sends warning information to the user or external devices via audible and visual signals or a wireless transmission module, specifically using a buzzer in the main control module 200 or a Bluetooth communication module.

[0071] When the temperature sensor 128 detects that the user's chest temperature exceeds a preset value, the main control module 200 immediately adjusts the contact pressure judgment threshold to a lower baseline threshold, thereby reducing the inflation volume of the pneumatic airbag 129 to alleviate local pressure. If the body temperature does not drop below the preset value within the adjusted set time (e.g., 10 minutes), the main control module 200 will trigger an alarm mechanism to alert the user that there may be a health abnormality or that the clothing is too tight.

[0072] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope of the claims.
