[0023] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention.

[0024] See also Figures 1 to 4 It should be noted that the illustrations provided in this embodiment are merely schematic illustrations of the basic concept of the present invention. Therefore, the illustrations only show components relevant to the present invention and are not drawn according to the number, shape, and size of components in actual implementation. In actual implementation, the type, quantity, and proportion of each component may be arbitrarily changed, and the component layout may also be more complex.

[0025] See also Figure 1 This embodiment provides a knee pad for collecting data. The knee pad is worn at the knee joint. When the knee joint moves, the knee pad can collect data, thereby understanding the activity of the muscle groups around the knee joint.

[0026] The knee pad includes a clothing piece 1, at least one flexible sensor 2 and a data interface 3. The clothing piece 1 is configured to cover the human knee. The flexible sensor 2 is provided on the clothing piece 1 and is configured at a position corresponding to the knee joint muscle group. The flexible sensor 2 is used to collect data during knee joint movement. The data interface 3 is provided on the clothing piece 1 and connected to the flexible sensor 2. The data interface 3 is used to transmit data.

[0027] When the clothing piece 1 is worn on the human knee, the clothing piece 1 covers the knee joint muscle group. At this time, the flexible sensor 2 corresponds exactly to the position of the muscle group. When the knee joint flexes and extends, the flexible sensor 2 will capture the movement of the muscle to monitor the changes in muscle activity. At this time, the flexible sensor 2 generates an electrical signal, which is transmitted to the external device through the data interface 3.

[0028] The knee brace of this embodiment has a flexible usage scenario. By providing a data interface 3, it can be connected to various processing terminals and can be used for rehabilitation monitoring in medical settings, health monitoring, sports monitoring, and motion capture in VR. For example, in the field of motion detection, the real-time data from the flexible sensor 2 can be combined with an algorithm to analyze indicators such as joint angles, speed, cadence, and stride length. This not only captures movement details, but also generates personalized motion analysis and improvement suggestions based on this data, effectively preventing sports injuries.

[0029] In this embodiment, the garment panel 1 is configured to cover at least the quadriceps femoris, tibialis anterior, tibialis longus, and gastrocnemius muscles surrounding the knee joint. The coverage area of ​​the garment panel 1 can be expanded according to the design to monitor more muscle groups. The garment panel 1 is made of a single piece, and the elastic material of the garment panel 1 allows for good adhesion to the skin without falling off.

[0030] To prevent incorrect wearing, the square garment piece 1 is also provided with an auxiliary wearing mark 11. This mark 11 corresponds to the tibialis anterior muscle and is circular. Specifically, the mark 11 surrounds the patella to locate the position of the knee brace. This allows the user to wear the knee brace more accurately, avoiding deviation and incorrect wearing, promoting standard wear, and ensuring that the flexible sensor 2 is always in the target area during each use.

[0031] See also Figure 2 and Figure 3 In this embodiment, the flexible sensor 2 can be attached to the surface of the clothing panel 1 or embedded within the clothing panel 1 (i.e., within the interlayer of the clothing panel 1), without limitation. The number of flexible sensors 2 is multiple, for example, four. Each of the four flexible sensors 2 is connected to the data interface 3. The four flexible sensors 2 are configured on the clothing panel 1 corresponding to the quadriceps femoris, tibialis anterior, tibialis longus, and gastrocnemius muscles, respectively. The quadriceps femoris is a key muscle group that affects knee flexion and extension. Placing a flexible sensor 2 at the quadriceps femoris can accurately detect knee flexion and extension. By monitoring this area, movements such as running and jumping can be analyzed. The tibialis anterior muscle plays a key role in leg movements, such as lifting the foot or stepping. Placing the flexible sensor 2 at the tibialis anterior muscle can help capture subtle deformations in footsteps and effectively analyze the activity of the tibialis anterior muscle during exercise. The tibialis longus muscle is responsible for controlling dorsiflexion of the foot and stability of the ankle joint. By monitoring the tibialis longus muscle, we can better understand the dynamics of the foot and ankle during running, thereby predicting athletic performance. The gastrocnemius muscle directly influences the pushing motion during running and gait. Monitoring the deformation of the gastrocnemius muscle with the flexible sensor 2 can assess the performance of the ankle joint during movement, thereby analyzing important running metrics such as cadence and stride length.

[0032] See also Figure 1 and Figure 4In this embodiment, the type of flexible sensor 2 used is a flexible pressure sensor, a flexible resistive strain sensor or a flexible force strain sensor. The flexible sensor 2 includes a stretchable conductor 21 and two connecting ends 22. The stretchable conductor 21 is arranged at a position corresponding to the knee joint muscle group and is connected to the data interface 3. When the muscle group around the knee joint moves, the stretchable conductor 21 will deform accordingly. At this time, the stretchable conductor 21 can generate an electrical signal and transmit data through the data interface 3. In this process, the stretchable conductor 21 is used to collect data. The two connecting ends 22 are connected to the data interface 3. The stretchable conductor 21 is connected to the data interface 3 through the two connecting ends 22. The stretchable conductor 21 is liquid metal. For example, the liquid metal is gallium-indium alloy, gallium-tin alloy, gallium-indium-tin alloy or gallium-zinc alloy. The advantage of using such liquid metal materials is that they have good electrical conductivity, tensile durability and biosafety.

[0033] In this embodiment, the stretchable conductor 21 is arranged in a pattern on the garment panel 1. For example, a portion of the stretchable conductor 21 is bent into an S-shape. This bending helps capture the lateral force movement of the muscles, resulting in higher data accuracy. In other embodiments, the stretchable conductor 21 can also be bent into other shapes, which are not limited here.

[0034] In this embodiment, in order to enable the flexible sensor 2 to capture muscle movement more sensitively, the flexible sensor 2 is arranged along a direction perpendicular to the muscle stretching force.

[0035] Data interface 3 can be connected to data boxes and other signal collection and processing equipment. The specific selection can be based on the application scenario and is not limited here.

[0036] In summary, the knee brace of this embodiment is implemented as follows: Apparel piece 1 is worn on the human knee, with the auxiliary wear mark 11 encircling the patella. This ensures that the apparel piece 1 covers the knee joint muscle group, with the flexible sensor 2 precisely aligned with the muscle group. When the knee joint flexes and extends, or performs other movements, the flexible sensor 2 captures muscle movement to monitor changes in muscle activity. This generates an electrical signal, which is transmitted via a data interface 3 to an external data acquisition and processing device. Therefore, this utility model effectively overcomes the shortcomings of the prior art and possesses high industrial value.

[0037] This embodiment further provides a wearable device, which includes the above-mentioned knee pad. It is understandable that the wearable device may include elbow pads and other devices in addition to the knee pad.

[0038] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
