[0027] In order to better understand the purpose, structure and function of the present invention, a breathing visualization clothing of the present invention is further described in detail below in conjunction with the accompanying drawings.

[0028] With the development of textile science and technology, smart fabrics that integrate sensor materials, information science, data processing and storage, and ergonomics have become a hot research direction in the field of high-tech textiles. Flexible stretch sensors are currently mainly used in medical health, electronic products, robots and other fields. This embodiment is based on the working characteristics of flexible stretch sensors to solve the problem of difficulty in monitoring the breathing process.

[0029] Figure 1 This is a front structural schematic diagram of a breathing visualization garment according to an embodiment of the utility model. Figure 2 FIG. 1 is a schematic diagram of the back structure of a breathing visualization garment according to an embodiment of the present invention. Figure 1 and Figure 2 As shown, the breathing visualization clothing includes: a clothing body 1 suitable for being worn on the body, and a power module 2, a flexible stretch sensor 4, a main control board 3 and a light module 5 arranged on the clothing body;

[0030] The main control board 3 is respectively connected to the power module 2, the flexible stretch sensor 4 and the light module 5 through flexible wires. The flexible stretch sensor 4 is arranged at a position corresponding to the breathing monitoring part of the body on the clothing body 1, and the light module 5 is arranged on the outer surface of the clothing body 1;

[0031] The main control board 3 is used to generate a control signal for controlling the light module 5 to change light and dark according to the electrical signal output by the flexible stretch sensor 4. The main control board 3 is an independently working hardware and does not rely on other software and programs.

[0032] Specifically, the flexible stretch sensor 4 is connected to the main control board 3 via a first flexible wire 6 , the lighting module 5 is connected to the main control board 3 via a second flexible wire 7 , and the power module 2 is connected to the main control board 3 via a third flexible wire 8 .

[0033] In a specific embodiment, the lighting module 5 includes multiple LEDs, the positive pole of each LED is connected to different output pins of the main control board 3 through a flexible wire, and the negative poles of the multiple LEDs are gathered through the flexible wire and then connected to the ground pin of the main control board 3.

[0034] In a specific embodiment, the garment body 1 may be a tight-fitting garment, so that the breathing of the wearer can be monitored. Figure 3a The figure shows a front view of a garment body in one embodiment of the utility model. Figure 3b The back schematic diagram of the clothing body in one embodiment of the utility model is shown. The clothing body 1 is composed of an outer tight waist short sleeve and an inner bra. The fabric of the clothing body 1 is soft and elastic and fits the skin. The abdominal changes caused by human breathing will cause the close-fitting clothing to deform, which is convenient for monitoring the small changes in human breathing. Optionally, the fabric of the clothing body 1 is composed of 85% nylon and 15% spandex.

[0035] The flexible stretch sensor 4 is a sensor designed to maintain its function under non-rigid conditions such as deformation, bending or stretching. In a specific implementation, the sensitivity of the flexible stretch sensor 4 is improved by changing the sensitivity of the flexible stretch sensor 4 or replacing the outer layer of the flexible stretch sensor 4 with a thinner fabric.

[0036] In a specific embodiment, a capacitive flexible stretch sensor is used, which mainly includes a flexible substrate, a sensor microchannel, a conductive sensing material, a flexible wire, a sensor flexible package and a subsequent signal processing circuit. These parts work together to enable the sensor to achieve high stretchability and have good flexibility and elasticity. Its working principle is that stress triggers sensor deformation, deformation triggers changes in sensor capacitance, reads the capacitance, and reacts to stress and strain. The trigger stress of the flexible stretch sensor is 0.2N, the allowable range of tension is 0~10N, the corresponding sensor length variation range: 0~50%, the line length is 99.9%, the durability is more than 300,000 times, and the working stability is less than 60 degrees Celsius.

[0037] Among them, when the deformation of the capacitive flexible stretch sensor increases, the electrical signal output by it is usually enhanced (the capacitance value increases); and when the deformation decreases, the electrical signal weakens (the capacitance value decreases). This change rule is the basis for realizing deformation monitoring, force sensing, touch recognition and other functions. Correspondingly, during the inhalation process, the abdomen gradually expands, the deformation of the capacitive flexible stretch sensor gradually increases, and the brightness of the light module 5 gradually increases; during the exhalation process, the abdomen gradually contracts, the deformation of the capacitive flexible stretch sensor gradually decreases, and the brightness of the light module 5 gradually decreases.

[0038] The flexible wire is a conductive sewing thread used for sewing circuits on clothing, which is used to connect various hardware modules. The flexible wires do not cross and the spacing is greater than a threshold value, so as to avoid short circuits caused by line crossing. After sewing, the flexible wires need to be insulated. In a specific embodiment, the flexible wire is a silver fiber wire made of nylon with silver plated surface, for example, a silver fiber wire with a silver content of more than 18%. Specifically, the breathing visualization clothing also includes an insulator covering the flexible wire, and the insulator is covered on the flexible wire to achieve insulation treatment of the flexible wire. The insulator can be fabric glue, fabric paint or fabric layer. Insulation treatment is achieved by covering the surface of the flexible wire with a layer of fabric glue, fabric paint or the flexible wire is covered by satin embroidery.

[0039] The breathing monitoring part refers to the part that can change significantly when the human body breathes. In a specific embodiment, the flexible stretch sensor 4 is set on the clothing body 1 at a position corresponding to the front abdomen of the body. When the abdomen of the human body breathes, the flexible stretch sensor 4 causes the deformation of the flexible stretch sensor 4, and the flexible stretch sensor 4 as the input end senses the deformation and changes the capacitance, causing the current to change and changing the state in the circuit. The main control board 3 is the core of signal monitoring and processing, and is used to generate a control signal that can make the light module 5 emit light according to the electrical signal output by the flexible stretch sensor 4; the light module 5 is the output end, and the electrical signal change is fed back to the wearer in the form of light changes, so as to achieve the visualization effect of the light module 5 changing light and dark following the human body's breathing process.

[0040] Figure 4 A schematic diagram of the working principle of the breathing visualization clothing according to an embodiment of the utility model is shown. As shown in the figure, the power module 2 supplies power to the main control board 3, the human body's breathing drives the flexible stretch sensor 4 to stretch, and the flexible stretch sensor 4 outputs a signal to the main control board 3. The main control board 3 processes the received electrical signal to generate a control signal for controlling the light module 5 to emit light.

[0041] The power module 2 and the main control board 3 are arranged at a position corresponding to the back of the body on the clothing body 1. Further, the position corresponding to the back of the body on the clothing body 1 has two layers of fabric, and the main control board 3 and the power module 2 are arranged in the middle of the interlayer formed by the two layers of fabric. Further, the power module 2 and the main control board 3 are arranged in the middle of the interlayer of the fabric at the back of the bra of the clothing body 1 and the surface fabric.

[0042] In a specific embodiment, the power module 2 is arranged on the clothing body 1 through a connector. The connector can be a metal snap fastener, such as a copper snap fastener, so that the power module 2 is arranged as a detachable part, which facilitates the installation and removal of the power module 2.

[0043] In a specific embodiment, the lighting module 5 includes a plurality of SMD LEDs, which are arranged on the clothing body 1 at a position corresponding to the chest of the body, and are connected to the main control board 3 through a flexible conductor, and have an operating voltage of 3-5V and an operating current of 40mA.

[0044] In a specific embodiment, the power module 2 includes a button battery and a button battery holder, such as a CR2032 button battery and a CR2032 button battery holder module.

[0045] The CR2032 button battery uses lithium metal as the negative electrode and manganese dioxide as the positive electrode, and belongs to the chemical battery system. The maximum size is usually 20.0mm (diameter) * 3.2mm (thickness), and the weight is usually 3.0g. The nominal capacity of the CR2032 button battery is usually 210mAh, and the capacity of some CR2032 button batteries can reach 240mAh. The CR2032 button battery can withstand a maximum continuous current of 20mA. The CR2032 button battery holder module uses CR2032 batteries and is composed of two pairs of positive and negative connection points, a slide switch, a metal coin battery mounting port, and a coin battery holder.

[0046] The edge of the main control board 3 has conductive holes. Before sewing, determine the placement of the modules to be sewn on the cloth, and draw a circuit on the cloth to connect the modules. The specific steps of the sewing process are as follows:

[0047] 1. Threading the Needle Before you begin sewing, tie a knot at the long end of the thread to prevent pulling the thread completely through the fabric.

[0048] 2. Sew the first starting knot on the fabric.

[0049] 3. Sewing the main control board: Each time the thread passes through the sewing hole, it should be looped three to four times to ensure that the contact between the energized wire and the sewing hole is firm. After tightening, leave a certain amount of thread to connect other modules.

[0050] 4. Sew the circuit part: straighten the thread so that it is flush with the fabric, and sew forward step by step along the direction of the circuit through the fabric. Repeat this process, keeping the stitches evenly spaced while sewing.

[0051] 5. When connecting multiple main control boards, keep one conductive sewing thread energized and continue sewing to the next board.

[0052] 6. After sewing the holes with the same electrical level, cut the conductive sewing thread short and tie a knot.

[0053] 7. To avoid accidental short circuits after the circuit is sewn to the fabric and tested, the wires need to be insulated: you can cover the wires with a thin layer of fabric glue, fabric paint or an extra layer of fabric, or cover the circuit with satin embroidery.

[0054] In a specific embodiment, the clothing body 1 can be a tights suitable for yoga training, so that the breathing of the wearer during yoga exercises can be monitored. Yoga practitioners mainly use abdominal breathing during the entire practice, so the flexible stretch sensor is sewn on the abdomen of the yoga clothing. The brightness of the LED light is weak before the wearer starts to inhale, and the brightness of the LED light reaches the brightest when the wearer inhales to the maximum extent. During the wearer's exhalation, the LED light gradually dims to the brightness at the beginning.

[0055] In summary, the embodiment of the utility model realizes breathing visualization clothing based on flexible stretch sensors. On the one hand, the flexible stretch sensor is used to measure the changes in human breathing. On the other hand, the measured value is processed by the main control board to obtain a control signal, which is used to control the light module to emit light, thereby realizing the visualization of breathing. Specifically, the flexible stretch sensor produces a change in capacitance as the human breathing changes, and at the same time, the current can be changed to make the light change, thereby realizing the visualization of human breathing, allowing the wearer to monitor the breathing frequency and breathing changes more conveniently and intuitively, thereby adjusting the breathing rhythm and better mastering the correct breathing method, which provides a new idea for the application of flexible stretch sensors in the field of smart wearables.
