Description

Technical Field

[0001] This utility model relates to the field of vital sign detection technology, specifically a motion sensing garment. Background Technology

[0002] Real-time monitoring of vital signs during exercise is crucial, enabling timely tracking of changes in physiological indicators such as heart rate and body temperature, and effectively preventing sports injuries. However, existing apparel products have significant technical limitations: on the one hand, traditional sportswear lacks vital sign monitoring functions, failing to meet users' needs for real-time access to sports health data; on the other hand, some smart garments, in order to achieve washability protection, permanently embed sensor modules into the inner layer of the clothing, resulting in a fabric barrier between the modules and the skin. During exercise, relative displacement can easily occur due to clothing deformation and changes in body position, making it difficult to maintain stable skin contact, causing fluctuations or loss of monitoring signals, seriously affecting the accuracy and reliability of data collection. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a motion-sensing garment, comprising a garment body and a detachable sensing module. The garment body has a functional pocket on its inner side, with a hidden snap opening on its upper side. A rectangular hole is located in the center of the functional pocket. An elastic conductive layer is sewn into the functional pocket at the rectangular hole. The elastic conductive layer is woven with conductive fiber circuitry, the ends of which terminate at several metal contacts. Neodymium magnets are uniformly fixed around the rectangular hole in the functional pocket, and these magnets are used to magnetically attach the sensing module. The sensing module includes a housing, on which magnets with polarities matching the positions of the neodymium magnets in the garment body are mounted. A spring-loaded pin contact corresponding to the metal contacts is also located at the bottom of the housing, and the spring-loaded pin contact can connect to the metal contacts.

[0004] The housing contains a microprocessor, a micro battery, an electrocardiogram (ECG) biosensor, a skin temperature sensor, and a wireless transmission unit; the micro battery is electrically connected to the microprocessor; the microprocessor is electrically connected to the ECG biosensor, the skin temperature sensor, and the wireless transmission unit, and the ECG biosensor is electrically connected to a spring array contact.

[0005] In a specific implementation, the electrocardiogram biosensor uses a dry electrode type ADS1292 chip.

[0006] The skin temperature sensor is an NCP15WF104F03RC surface mount thermistor.

[0007] The metal contacts are gold-plated, which can effectively prevent sweat from causing corrosion and increasing contact resistance during exercise.

[0008] To improve the comfort of wearing the garment, the neodymium magnet has a size of Φ6mm×3mm.

[0009] The functional patch is made of a skin-friendly and breathable fabric blended with 80% cotton and 20% spandex.

[0010] The thickness of the functional patch is 0.3 mm.

[0011] Beneficial effects: This utility model is a sports sensing garment. By setting a functional pocket on the inside of the garment body, neodymium magnets are used to achieve magnetic detachable installation of the sensing module, avoiding the water damage problem caused by the permanent embedding of traditional smart garment modules. The polarity matching design of neodymium magnets allows the sensing module to be automatically guided back into position after being placed in the pocket, without the need for precise alignment. Moreover, the magnetic attraction force can withstand the centrifugal force of running, jumping and other movements, solving the problem of unstable contact caused by fabric obstruction and displacement of traditional embedded modules. At the same time, the elastic conductive layer directly contacts the skin to transmit biological signals. By integrating electrocardiogram biosensors and skin temperature sensors, it can collect vital signs data such as heart rate and body temperature in real time, realizing the monitoring of vital signs during exercise.

[0014] Exemplary embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings.

[0015] See Figure 1-2This embodiment provides a motion-sensing garment, including a garment body 1 and a detachable sensing module. A functional pocket 2 is provided on the inner side of the garment body 1. The functional pocket 2 is made of the same fabric as the garment body 1, using a skin-friendly and breathable fabric blended from 80% cotton and 20% spandex. The functional pocket 2 is 0.3mm thick to ensure comfort for the wearer. A hidden snap opening is provided on the upper side of the functional pocket 2, which is used to open and close the functional pocket 2 and the garment body 1 via a snap fastener assembly 3. The hidden snap opening is used to place the sensing module inside the functional pocket 2. A rectangular hole is provided in the center of the functional pocket 2; an elastic conductive layer 5 is sewn into the rectangular hole of the functional pocket 2. The elastic conductive layer 5 is made of silver-coated nylon fiber and polyurethane elastic fiber blend, and can directly contact the skin. The elastic conductive layer 5 is woven with conductive fiber circuit 6, which can conduct electrical signals during human movement. The endpoints of the conductive fiber circuit 6 terminate at several metal contacts 7, which can be electrically connected to the sensing and monitoring module, thereby transmitting the electrical signals of the conductive fiber circuit 6 to the sensing and monitoring module through the metal contacts 7.

[0016] Meanwhile, to ensure the sensor monitoring module remains firmly connected to the metal contact 7 after installation, neodymium magnets 4 are evenly fixed around the rectangular opening of the functional patch 2. Each neodymium magnet 4 measures Φ6mm×3mm, a small size that will not cause discomfort during movement. The neodymium magnets 4 can align and magnetically attract the magnets on the sensor monitoring module, firmly fixing the module inside the functional patch 2 for collecting human feature information. Compared with traditional Velcro or snap fasteners, this magnetic structure has significant advantages: firstly, precise alignment is not required during installation, as the magnets automatically guide the module into position; secondly, the magnetic attraction is strong, able to withstand the centrifugal force generated during running, jumping, and other movements without falling off.

[0017] The sensing and monitoring module includes a housing, on which magnets with polarities matching the positions of neodymium magnets 4 on the garment body 1 are installed. The bottom of the housing also has spring-loaded pin contacts corresponding to metal contacts 7, which can connect to the metal contacts 7. When the sensing and monitoring module is placed inside the functional patch pocket 2, the neodymium magnets 4 automatically align and attract with the magnets on its housing, thereby ensuring precise contact between all spring-loaded pin contacts and the metal contacts 7 on the garment body 1.

[0018] To collect and detect human characteristic information during exercise, the housing houses a microprocessor, a microbattery, an electrocardiogram (ECG) biosensor, a skin temperature sensor, and a wireless transmission unit. These components are electrically connected via a flexible PCB board. The microbattery is electrically connected to the microprocessor, providing power to the entire sensor monitoring module. The microprocessor is electrically connected to both the ECG biosensor and the skin temperature sensor. The ECG biosensor uses a dry-electrode ADS1292 chip, whose electrode pins are connected to the conductive fiber circuit 6 of the elastic conductive layer 5 via spring-loaded contacts. This allows it to collect ECG signals from the human body surface. Furthermore, to ensure the accuracy of the detected electrical signals, the metal contacts 7 are gold-plated, effectively preventing corrosion caused by sweat during exercise and thus reducing contact resistance.

[0019] The skin temperature sensor uses an NCP15WF104F03RC surface-mount thermistor, which senses changes in body temperature through thermal conduction. Based on the resistance change of the thermistor, it outputs an electrical signal that is transmitted to a microprocessor. The microprocessor obtains the body temperature value detected by the skin temperature sensor based on the electrical signal. The microprocessor is electrically connected to a wireless transmission unit, which in turn connects to a user terminal, such as a smartphone, to upload the monitored human vital signs information to the terminal device. The user terminal's app can display vital signs parameters such as heart rate curves and body temperature changes in real time, and issue alarms when abnormal vital signs parameters are detected.

[0020] In addition, to prevent the sensing module from stopping due to insufficient power, a wireless charging coil is provided on the top of the sensor module's casing. The wireless charging coil is connected to a micro battery and can charge the sensing module wirelessly.
