[0002] Wearable devices are intelligent computing devices that can be worn or installed on the human body to sense, transmit, and process physiological information released by the body, providing real-time health status analysis. In recent years, wearable devices have made significant progress driven by materials science, electronics, and nanotechnology, especially in flexible materials, biocompatibility, and multifunctional integration. Wearable devices require flexible sensors, which are sensors that can maintain their performance under external forces such as bending, twisting, or compression. They are usually composed of flexible substrate materials and sensitive materials, and are suitable for wearable devices, medical health monitoring, robotics, and other fields. Existing flexible sensors mainly consist of a base layer and a conductive layer printed on it. The conductive layer is mostly composed of interdigitated electrodes, which are mostly printed by screen printing. Currently, they are all horizontally printed, making it difficult to ensure sufficient paste on each printed area, resulting in uneven printing, poor quality of the interdigitated electrodes, impaired conductivity, and reduced sensing effect.

[0003] Chinese patent application CN 202210526630.7, filed on May 13, 2022, discloses a flexible pressure sensor comprising a polyurethane encapsulation layer, a gel electrolyte layer, a first electrode, a second electrode, and a flexible PET substrate. The side of the gel electrolyte layer in contact with the first and second electrodes has an irregular microstructure. The first and second electrodes are symmetrically arranged on the flexible PET substrate. By adjusting the impedance between the first and second electrodes, a response to dynamic and static pressure stimuli can be achieved. This fabrication method is simple and convenient, effectively reducing production costs. However, the above technology does not solve the problems of low quality and poor conductivity of the interdigitated electrodes.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this patent application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

All the first and second support columns are equipped with sliding parts at their bottoms, and the sliding parts are in sliding cooperation with the material changing slide rail; The height of the first support column is greater than the height of the second support column.

[0011] The inner wall of the storage platform is slidably connected to baffles on both sides, and two guide rods are installed on the top of the baffles; An L-shaped plate is installed on the inner wall of the storage platform below the baffle. The vertical plate of the L-shaped plate contacts the baffle, the bottom of the baffle is connected to the top of the piston, the piston slides with the L-shaped plate, there is no material chamber between the piston and the vertical plate of the L-shaped plate, and two return springs are provided between the side of the piston and the vertical plate of the L-shaped plate. The piston reciprocates along the horizontal plate of the L-shaped plate.

[0012] A return zone is formed between the piston, the horizontal plate of the L-shaped plate, and the inner wall of the storage platform away from the screen printing plate. The top of the horizontal plate of the L-shaped plate is provided with multiple evenly distributed leakage holes located in the return material area. The return material area and the discharge chamber are connected through a leakage hole, while the area between the piston and the vertical plate of the L-shaped plate is not connected to the discharge chamber.

[0013] Rollers are provided at both ends of the scraper, and the rollers contact the two guide rods along the screen printing plate, the arc surface, the baffle.

[0014] The two guide rods are located at one-quarter to three-quarters of the length of the baffle, and the distance between the two guide rods is less than the distance between the two rollers.

[0015] The inner walls of the storage platform are equipped with adjustable slide rails on both sides, and the sides of the baffles are slidably engaged with the two adjustable slide rails.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In a wearable sensor manufacturing system based on screen printing, one end of a storage platform is provided with an inclined placement plate. One end of a screen printing plate is inclinedly positioned in the area between the storage platform and the placement plate. The connection between the placement plate and the storage platform is an arc-shaped surface. The other end of the screen printing plate is positioned on a fixed track. Two fixing components are slidably fitted on the fixed track, and the two fixing components clamp the left and right sides of the screen printing plate respectively. In application, the screen printing plate is placed in an inclined state on the fixed track and the placement plate, and then the two fixing components are moved to hold the screen... The printing plate is fixed, and then the ink is placed above the squeegee. The squeegee is pushed diagonally upwards along the screen printing plate, allowing the ink to accumulate abundantly at the bottom of the squeegee. This ensures sufficient ink per unit area, printing the ink onto the base layer of the printing plate. The printed conductive layer and its base layer are then removed from the printing plate, and a new base layer is transported, repeating the above operation. The diagonal pushing of the squeegee ensures ample ink throughout, improving printing uniformity and resulting in better screen printing quality. This, in turn, improves the quality of the interdigital electrodes, resulting in stable electrical signals, high ink utilization, and better sensor performance. Therefore, the interdigital electrodes of this invention have high quality, good conductivity, and excellent sensor performance.

[0017] 2. In this invention, a wearable sensor manufacturing system based on screen printing, a clamping block slides with a fixed track. The side of the clamping block contacts the side of the screen printing plate. An adjusting bolt is threaded into the center of the top of the clamping block, with one end passing through the clamping block and connecting to the top of a positioning plate. The bottom of the positioning plate abuts against a groove in the fixed track. In application, two sliding blocks at the bottom of the clamping block move along the fixed track towards the screen printing plate. Then, the adjusting bolt is rotated downwards to abut the positioning plate against the groove, thus fixing the clamping block and subsequently the screen printing plate. The clamping is stable and simple, and can be adjusted according to different usage angles and heights. The large bottom space facilitates the passage of the substrate on the material plate and adapts to printing pastes of different viscosities. Therefore, this invention is convenient to fix and highly practical.

[0018] 3. In this invention, a wearable sensor manufacturing system based on screen printing, two guide rods are located at one-quarter to three-quarters of the baffle length. The distance between the two guide rods is less than the distance between the two rollers. During application, if the guide rods are positioned too far forward after the ink flows out, they may fall into the discharge chamber during the scraper's return movement, causing obstruction or damage to the scraper. Positioning them at one-quarter to three-quarters ensures smooth and normal scraper movement, enhancing safety. Therefore, this invention is safe to use and provides smooth movement.

[0019] 4. In this invention, an wearable sensor manufacturing system based on screen printing is provided. An L-shaped plate is installed on the inner wall of the storage platform below a baffle. The vertical plate of the L-shaped plate contacts the baffle, and the bottom of the baffle connects to the top of a piston. The piston slides in conjunction with the L-shaped plate. Two return springs are provided between the side of the piston and the vertical plate of the L-shaped plate. During application, the squeegee slides to the two guide rods, and the roller drives the baffle to move, thereby opening the discharge chamber and allowing the ink to flow out. Then, the squeegee moves in the opposite direction, carrying the ink for printing. Simultaneously, the return springs drive the piston to reset, causing the baffle to move in the opposite direction, closing the discharge chamber, and the ink flows back to the return area. This makes ink retrieval more convenient, reduces ink exposure time, reduces ink waste, and saves costs. Therefore, this invention provides convenient ink retrieval and saves costs.

[0041] The following are supplementary descriptions of the present invention: Because the connection between the bottom of the screen printing plate 2 and the storage platform 1 is an arc-shaped surface 15, the squeegee 3 moves more smoothly from the storage platform 1 to the screen printing plate 2, avoiding the paste getting stuck in this area and affecting normal manufacturing.

[0042] Example 1: A wearable sensor manufacturing system based on screen printing is disclosed. The system includes a storage platform 1, a screen printing plate 2, a squeegee 3, and two fixing components 5. One end of the storage platform 1 is provided with an inclined placement plate 13.

[0048] Example 4: Example 4 is basically the same as Example 1, except that: An L-shaped plate 16 is installed on the inner wall of the storage platform 1 below the baffle 11. The vertical plate 161 of the L-shaped plate 16 contacts the baffle 11, and the bottom of the baffle 11 is connected to the top of the piston 111.

[0049] In application: The scraper 3 slides to the two guide rods 12, and the roller 31 drives the baffle 11 to move, so that the piston 111 pulls the return spring 17, thereby opening the discharge chamber 14. Under the pressure of the piston 111, the slurry flows out of the discharge chamber 14 through the return zone 164 and the leakage hole 163. Then the scraper 3 moves in the opposite direction to carry the slurry for printing. At the same time, the return spring 17 drives the piston 111 to reset, so that the baffle 11 moves in the opposite direction to close the discharge chamber 14. The slurry flows back to the return zone 164 from the leakage hole 163. At this time, the slurry inside the storage platform 1 is at the same height in the discharge chamber 14 and the return zone 164, and there is no slurry in the empty chamber 165.
