Description
Technical Field
[0001] This application relates to the field of signal acquisition device processing technology, specifically to a high-precision, self-adhesive, stretchable, multimodal pattern system and its construction method. Background Technology
[0002] As human-machine collaborative technology develops towards "naturalness, precision, and safety," and especially with the continuous emergence of new technology scenarios, motion behavior perception in complex environments becomes particularly important. Flexible motion-sensitive systems, which are devices in behavioral monitoring equipment that convert various minute movements into electrical signals, represent an important direction for development in fields such as motion monitoring and rehabilitation training.
[0003] The current mainstream motion capture technologies include: (1) depth-of-field camera technology based on computer vision, which has high requirements for environmental conditions such as changes in ambient light, optical interference, background stability, and climate. Moreover, the field of view of the camera itself is limited, and the motion behavior is easily obstructed by surrounding objects and itself, resulting in higher costs. (2) Inertial sensors based on MEMS and optical technology have rigid, hard structures and large volume shapes that are difficult to fit tightly with soft, flexible, and curved substrates such as human skin, muscles, and fingers in micro-environments, so they cannot truly and reliably reflect the actual motion state parameters. The portability, intelligence, sensitivity, aesthetics, or stealth of flexible motion devices have also put forward higher requirements. One of the significant features is multimodality, which enables accurate, safe, and efficient monitoring of motion behavior and can be applied to various action scenarios such as fitness, sports, and yoga. Due to its multimodal characteristics, it generates multi-level electrical signals for different human motion behaviors, realizing efficient acquisition and real-time monitoring of motion information, and timely detection and correction of non-standard motion behaviors. It provides more possibilities for applications in the field of behavior detection and has important research significance and broad application prospects. Summary of the Invention

[0027] As can be seen from the background technology, the existing technology has the following problems: high requirements for environmental conditions; limited field of view of the camera itself; easy obstruction of movement by surrounding objects and itself; high cost; and when using inertial sensors to capture behavior for motion detection, there are limitations such as the inertial sensors being difficult to fit closely with the human body, thus failing to capture small and subtle human movements.
[0028] Existing depth-of-field camera technologies suffer from drawbacks such as high environmental requirements, limited field of view, susceptibility to occlusion by surrounding objects and the camera itself, and high cost. Inertial sensors based on MEMS and optical technologies, on the other hand, are rigid, have a large size, and are difficult to integrate with soft, flexible, or curved substrates like human skin, muscles, and fingers in micro-environments. This makes them unable to capture subtle human movements and thus cannot accurately and reliably reflect actual motion parameters. Therefore, as human-machine collaborative technologies develop towards "natural, precise, and safe" approaches, motion perception in complex environments becomes particularly important.
[0029] To address the aforementioned technical challenges, this application provides a high-precision, self-adhesive, stretchable, multimodal pattern system and its construction method. This system aims to solve scientific movement problems such as posture calibration, rehabilitation training, and motion monitoring in complex sports, fitness, and rehabilitation environments. It achieves self-adhesion, flexibility, and stretchability of materials, and overcomes the limitations of traditional camera-based technologies, which are highly susceptible to environmental influences, have high costs, and rely on rigid inertial sensors whose hard structures and shapes make it difficult to adhere tightly to the human body, thus hindering the accurate acquisition of subtle, small-amplitude human movements. This enables accurate, safe, and effective acquisition of motion information, meeting the application needs of limb movement behavior monitoring systems in specific situations.
[0030] The purpose of this application is to provide a high-precision, self-adhesive, stretchable mechanical motion sensitive pattern system based on digital printing, which enables accurate, safe, and efficient real-time monitoring of motion behavior. It overcomes the problems of traditional detection technologies based on cameras, which are greatly affected by the environment and have high costs, and the rigidity, hard structure and shape of inertial sensors, which make it difficult to adhere tightly to the human body. It can accurately acquire small-amplitude and subtle human movements, making it more aesthetically pleasing, stealthy and multimodal, and can meet the application needs in specific scenarios, with broad development and application prospects.
[0031] The following description, in conjunction with the accompanying drawings, details a specific implementation scheme of a motion behavior monitoring, high-precision, self-adhesive, stretchable, multimodal functional pattern mechanical sensing system based on digital printing technology, which relates to this application.
[0032] See Figure 1 This application provides a method for constructing a high-precision, self-adhesive, stretchable, multimodal pattern system, including the following steps:
[0033] Step 1: Provide a flexible and stretchable conductive film material as the substrate for the motion-sensitive pattern system.
[0034] Step 2: Simulate the structural parameters of the motion-sensitive pattern system using simulation software, and then use drafting software to create the mechanical motion-sensitive pattern based on the structural parameters.
[0035] Step 3: Import the motion-sensitive pattern into the digital printing equipment, adjust the parameters of the digital printing equipment, and use the digital printing equipment to print the motion-sensitive pattern onto the flexible and stretchable conductive film material to obtain the digitally printed motion-sensitive pattern.
[0036] Step 4: Conduct a qualification inspection on the digitally printed motion-sensitive pattern. If the inspection is successful, a high-precision, self-adhesive, stretchable mechanical motion-sensitive pattern system is obtained.
[0037] This application relates to a method for constructing a high-precision, self-adhesive, stretchable, multimodal pattern system. Specifically, it involves a multi-level processing method for functional flexible capacitors, strain gauges, and electrodes using digital printing technology. This method aims to solve scientific motion problems such as posture calibration, rehabilitation training, and motion monitoring in complex motion environments like sports, fitness, and rehabilitation. It achieves self-adhesion, flexibility, and stretchability of materials, and overcomes the limitations of traditional camera-based technology, which is highly susceptible to environmental influences, has high costs, and suffers from the difficulty of accurately capturing subtle human movements due to the rigid structure and shape of inertial sensors. This enables accurate, safe, and effective acquisition of motion information, meeting the application needs of limb movement behavior monitoring systems in specific situations.
[0038] Specifically, step one provides a flexible and stretchable conductive film material. The flexible conductive film material can be obtained by directly purchasing commercially available products, such as ITO / PET, AgNW / PET, etc., or it can be prepared.
[0039] In some embodiments, see Figure 2 Flexible stretchable conductive film material includes a flexible substrate and a conductive material disposed on the flexible substrate; that is, flexible self-adhesive film material includes a flexible substrate (also known as a support substrate) and a conductive material; wherein, the substrate is one of polyethylene terephthalate, polydimethylsiloxane or thermoplastic polyurethane; the conductive material is one of stretchable silver-based, carbon-based or liquid metal conductive paste.
[0040] The preparation of a flexible and stretchable conductive film includes the following steps: selecting a flexible and stretchable substrate, choosing at least one material selected from polyethylene terephthalate (PET), polydimethylsiloxane (PDMS), thermoplastic polyurethane (TPU), etc., but not limited to these; cleaning the flexible and stretchable substrate using ultrasonic cleaning, with preferred ultrasonic cleaning conditions being an ultrasonic power of 60–120 W, an ultrasonic frequency of 40 kHz, a heating power of 100–300 W, a temperature of 50–60 °C, and a time of 10–20 min; drying at 50–60 °C for 5–10 min after cleaning; spin-coating silver nanowires (AgNW) onto the flexible and stretchable substrate, and curing to obtain the flexible and stretchable conductive film. The above cleaning process can be used or omitted as appropriate.
[0041] In some embodiments, the simulation software is Origin software, and the drafting software is CAD software.
[0042] Step two mainly involves designing the structure of the mechanical motion-sensitive pattern system.
[0043] The structure of the mechanical motion sensitive pattern system required in different scenarios is different. The structural design parameters of the mechanical motion sensitive pattern system that meet the preset conditions are obtained by simulating with Origin software, and then produced in computer-aided design (CAD) software to obtain the pattern required by the digital printing equipment and the format file compatible with it.
[0044] Step three mainly involves adjusting the parameters of the digital printing equipment, using the digital printing equipment to print mechanical motion-sensitive patterns, as well as the shape of the non-printed areas that serve as conductive paths.
[0045] In some embodiments, the digital printing technologies of the digital printing equipment include inkjet, screen printing, direct writing, and stencil printing.
[0046] In some embodiments, the motion-sensitive pattern is a multimodal functional pattern; the multimodal functional pattern has the shape of the printed area required by the digital printing device and the shape of the non-printed area as a conductive path; the format file of the multimodal functional pattern is a .dxf file.
[0047] In some embodiments, the motion-sensitive patterning system is a flexible device exhibiting dynamic fatigue stability of more than 10,000 cycles.
[0048] Step four mainly involves verifying the conformity of the mechanical motion-sensitive pattern.
[0049] In some embodiments, the conformity test includes checking whether the substrate of the digitally printed motion-sensitive pattern is damaged, whether the printing is complete, and whether the conductive path is broken.
[0050] Specifically, after printing, remove the motion-sensitive pattern and check whether the substrate of the motion-sensitive pattern is damaged and whether the multimodal motion-sensitive pattern is complete. Use a multimeter and a conductive tester to check whether the conductive path of the multimodal motion-sensitive pattern is continuous and complete, and whether the printed part is complete.
[0051] This application provides a high-precision, self-adhesive, stretchable, multimodal pattern system, which is fabricated using the construction method of the high-precision, self-adhesive, stretchable, multimodal pattern system described in the above embodiments, and is applied to motion behavior monitoring.
[0052] In some exemplary embodiments, the patterning system is connected to a signal acquisition system, which includes commercially available wireless, multi-channel, real-time acquisition hardware and host computer software.
[0053] This application also provides an application of the high-precision, self-adhesive, stretchable, multimodal patterning system described in the above embodiments for posture calibration, rehabilitation training, and motion monitoring in complex sports, fitness, or rehabilitation environments.
[0054] The following detailed description of the high-precision, self-adhesive, stretchable, multimodal pattern system and its construction method provided in this application is illustrated through specific embodiments.
[0055] Example 1
[0056] See Figure 2 , Figure 2a , Figure 2b , Figure 2c and Figure 2d The method for digitally printing multimodal mechanical motion-sensitive patterns provided in this embodiment specifically includes the following steps:
[0057] (1) Commercially available AgNW / PET was selected as the flexible conductive film;
[0058] (2) Create a mechanical motion-sensitive pattern structure that meets preset conditions in CAD software to obtain the pattern required by the digital printing equipment. For example... Figure 2 The image shows a multimodal mechanical motion sensitive pattern system. The pattern system has different pattern structures distributed on both sides of a flexible and stretchable conductive film. The line width of the pattern on one side is 400 μm, the radius of the circular endpoint is 1.5 mm, the rectangular endpoint is 1.5 mm × 3 mm, and the spacing between the two rectangles is 1.2 mm. The pattern on the other side has long lines on both sides with a size of 1 mm × 3 cm and a spacing of 9 mm between the two long lines. The short line in the middle has a size of 8 mm × 400 μm and a spacing of 500 μm between the short lines.
[0059] (3) Import the prepared mechanical motion sensitive pattern into the digital printing equipment and set the printing area on the software of the digital printing equipment; peel off the protective film layer of the flexible conductive film, place it on the digital printing platform and fix it; use the digital printing equipment to print the flexible conductive film. After the digital printing is completed, take out the printed area of the flexible transparent conductive film, and use a multimeter and a conductive test pen to check its qualification, and obtain the flexible stretchable mechanical motion sensitive pattern.

[0062] Figure 2d Optical microscope images of the patterns on both sides of the mechanical motion-sensitive patterning system.
[0063] Example 2
[0064] See Figure 3a and Figure 3b This embodiment provides a method for characterizing multimodal signals by digitally printing multimodal mechanical motion-sensitive patterns:
[0065] The prepared multimodal mechanical motion sensitive pattern was subjected to detection of both electrical and mechanical signals. As the flexible conductive film stretched, the capacitance value on the pattern changed due to the capacitance effect, thus generating a clear electrical signal. When the strain distance on the pattern changed, the pattern system could respond quickly and sensitively, accurately generating the corresponding strain force signal. By comprehensively processing these two signals, the system could output the response results according to the time sequence of the action to characterize the corresponding action. This series of performances fully demonstrates the accuracy and sensitivity of its multimodal monitoring.
[0066] Example 3
[0067] See Figure 4a , Figure 4b and Figure 4c This embodiment provides a method for digitally printing multimodal mechanical motion-sensitive patterns for accurate monitoring of multimodal signals in the field of motion detection:
[0068] Multimodal mechanical motion-sensitive pattern systems have a wide range of applications, especially in sports and fitness, medical rehabilitation, and movement correction, where they show great potential. Taking weightlifting as an example, multimodal mechanical motion-sensitive pattern systems can monitor the user's grip strength and finger flexion to ensure correct grip during the snatch, preventing slippage or hand injuries. By monitoring upper limb exertion, they can ensure that upper limb muscles are fully exercised. At the same time, they can further determine whether the user's clean and jerk movements are stable, preventing swaying or loss of balance.
[0069] In the field of medical rehabilitation, during the rehabilitation process after sports injuries or surgery, multimodal mechanical motion-sensitive pattern systems can monitor the patient's motion status in real time, including key indicators such as joint range of motion and muscle strength. This data helps physical therapists accurately assess rehabilitation progress, adjust rehabilitation plans, ensure training intensity, and correct improper movements during rehabilitation exercises, thereby accelerating the patient's recovery of normal motor function. Furthermore, by monitoring the patient's electromyographic signals to provide real-time feedback, this technology helps patients better understand their physical condition and improve the effectiveness of rehabilitation training. For example, by monitoring the patient's electromyographic activity, real-time muscle contraction feedback can be provided, helping the patient better master muscle training methods.
[0070] In the field of motion correction, multimodal mechanical motion sensitive pattern systems can combine computer vision technology to capture users' motion data in real time during sports training, such as muscle strength, joint range of motion, position, speed, acceleration, and angle. Furthermore, by processing and analyzing this motion data, errors or deficiencies in the motion can be identified, and targeted correction suggestions can be provided.
[0071] Based on the above technical solutions, this application provides a high-precision, self-adhesive, stretchable, multimodal pattern system and its construction method, specifically involving a multi-level processing method for functionalized flexible capacitors, strain gauges, and electrodes through digital printing technology, which has the following beneficial effects:
[0072] This application utilizes digital laser etching technology to etch conductive materials into predetermined electrode patterns, achieving high-precision, self-adhesive, stretchable mechanosensitive capacitor patterns. This enables efficient, safe, and accurate real-time acquisition of corresponding muscle electrophysiological, skin, or joint deformation signals during human movement. This application boasts advantages such as simple and rapid fabrication, high precision, strong flexibility, high safety, and multimodality. Furthermore, it overcomes the limitations of traditional camera-based detection technologies, which are highly susceptible to environmental influences and have high costs, as well as the limitations of rigid inertial sensors, whose hard structure and shape make it difficult to adhere tightly to the human body, thus hindering the accurate acquisition of subtle, small-amplitude human movements. This makes the application more aesthetically pleasing and stealthy, meeting the application needs of specific scenarios and possessing broad development and application prospects.
