[0031] Example 1: To address the problem that existing devices for preventing deep vein thrombosis in the lower extremities cannot provide intelligent control and individualized adjustment, referring to Figures 1, 2, and 3, this example proposes a flexible wearable piezoelectric material intelligent strap device. It mainly includes a main control module 2 and several functional straps 4. The main control module 2 is connected to all the functional straps 4. The main control module 2 mainly includes a data processor and an electrical energy processing unit, which are connected to the data processing unit. A piezoelectric module is mounted on each functional strap 4, and the piezoelectric module contacts the target area and applies corresponding pressure for massage. The piezoelectric module is also connected to a main control device 5, which is electrically connected to the main control module 2.
[0032] In this technical solution, the main control module 2 and the functional strap 4 are used to achieve flexible massage of the target area. The piezoelectric module can simulate the "muscle pump". Through the piezoelectric module and the main control module 2, intelligent massage adjustment and personalized treatment of human muscles can be achieved.
[0033] The number of functional straps 4 is not limited here, and can be flexibly adjusted and selected according to the actual situation of the target and the part of the body to be treated.
[0034] In this embodiment, there are four functional straps 4. The four functional straps 4 are respectively tied to the lower legs and thighs on both sides of the human body. The specific positions can be selected according to the actual needs of the human body.
[0035] Referring to Figure 2, in this embodiment, the main control module 2 is specifically the main control box, which is fixedly connected to the buckle 1 via a flexible strip.
[0036] In this embodiment, the main control box can be installed on the waist of the human body using a flexible strap and buckle 1. Of course, if the waist of the human body is not suitable for installation, a flexible fixation method using a flexible strap and buckle 1 can also be used. All of this is to meet the comfort of the human body, and the specific installation method is not limited.
[0037] Inside the main control module 2, that is, inside the main control box in this embodiment, there is a data processor and a power processing unit, which are electrically connected to each other. Since the main control box needs to be fixed to the waist or other parts of the human body, the data processor and power processing unit need to be lightweight.
[0038] In this embodiment, the weight of the main control box is approximately the same as that of a mobile phone, which weighs between 200g and 300g. This allows it to be adapted to people of different genders and weights, so that people can feel relatively unaffected or relaxed even when walking or running.
[0039] The main control module 2 is electrically connected to several functional straps 4. In order to ensure the stability of transmission monitoring and feedback adjustment, a data connection line 3 is used for connection, so as to realize the overall control and linkage of different functional straps 4.
[0040] Due to the piezoelectric module, the functional strap 4 integrates the functions of piezoelectric materials and sensors, enabling it to accurately assess muscle pressure at the application site and provide timely feedback and adjustment.
[0041] Referring to Figure 2, the main control device 5 is located on the side away from the functional strap 4 and the part of action. It has a structure of several straps. In this embodiment, two main control devices 5 are provided on each functional strap 4.
[0042] The main control device 4 can transmit data with the main control module 2. It can receive instructions from the main control module 2, parse them, and send the parsed results to the piezoelectric module for intelligent massage and pressure adjustment. It can also send the collected muscle pressure data and physiological parameters to the main control module 2 so that the main control module 2's data processor and power processing unit can perform corresponding data processing and conversion.
[0043] Similarly, the main control device 4 is also electrically connected to the main control module 2 via the data connection cable 3.
[0044] In this embodiment, the data processor can be the main control chip.
[0045] Referring to Figure 2, corresponding adhesive devices are provided on both sides of the functional strap 4 to make it easier to wear the functional strap 4; in this embodiment, the adhesive device is Velcro, but it can also be changed to other adhesive devices according to actual needs.
[0046] The functional strap 4 is embedded with a piezoelectric module, which includes an outer protective layer 6 and an inner protective layer 11. A first electrode 7 is provided on one side of the outer protective layer 6, and a second electrode 10 is provided on one side of the inner protective layer 11. A piezoelectric material 8 and a piezoelectric sensor 9 are provided between the first electrode 7 and the second electrode 10.
[0047] In this technical solution, the piezoelectric module consists of, from the outside to the inside, an outer protective layer 6, a first electrode 7, a piezoelectric material 8, a piezoelectric sensor 9, a second electrode 10, and an inner protective layer 11.
[0048] For the piezoelectric material 8, in this embodiment, the lead-free piezoelectric material KNN is specifically used, and both the outer protective layer 6 and the inner protective layer 11 are nylon matrix.
[0049] In this technical solution, the outer protective layer 6 is an outer nylon matrix, and the inner protective layer 11 is an inner nylon matrix.
[0050] Referring to Figure 3, the power processing unit includes a micro battery that powers the data processor and a rectifier unit connected to the micro battery. The rectifier unit is connected to a preprocessing unit, and the preprocessing unit is connected to the main control device 5 of the functional strap 4.
[0051] The main control module 2 is also connected to a remote control terminal, which can collect and analyze historical vibration signals and muscle pressure from the main control module 2 to train the lightweight model and send the data to the main control module 2's data processor.
[0052] In this technical solution, the corresponding lightweight model is trained and updated through a remote control terminal, and then distributed to the data processor of the main control module 2 on time or as needed.
[0053] Both the piezoelectric sensor 9 and the sensing module are connected to the main control device 5. The main control device 5 is connected to the power processing unit and the data processor, respectively. The main control device 5 is equipped with a storage unit to temporarily store the physiological parameters from the sensing module and send the physiological parameters to the data processor.
[0054] In this technical solution, the outer surface of the functional strap 4 is provided with two strip-shaped main control devices 5, which can apply voltage to the functional strap 4 and transmit pressure data to the main control module 2; the preprocessing unit can preprocess the signal data received by the main control module.
[0055] In this technical solution, the main control device 5 can simultaneously collect signal data from the piezoelectric sensor 9 and the sensing module, and send the signal data from the piezoelectric sensor 9 to the power processing unit and the data processor respectively, and send the data from the sensing module directly to the data processor.
[0056] After the main control device 5 sends the signal data of the piezoelectric sensor 9 to the power processing unit, the rectifier unit of the power processing unit can rectify the signal data, extract the signal strength information, and send the extracted information to the data processor.
[0057] Micro batteries can power power processing units and data processors.
[0058] In this embodiment, the sensing module can be a collection of multiple sensors, such as a body temperature sensor and a heart rate monitor. After monitoring these physiological parameters in real time, the sensing module directly sends them to the data processor via the main control device 5.
[0059] The piezoelectric sensor 9 emits mechanical waves and receives the reflected vibration signals. The main control device 5 analyzes muscle pressure by extracting the spectral characteristics of the vibration signals.
[0060] In this technical solution, the piezoelectric sensor 9 can monitor and acquire vibration signals in real time. After receiving the corresponding vibration signal, the main control device 5 extracts the spectral characteristics of the vibration signal.
[0061] The main control module 2 is also connected to a remote control terminal, which can collect and analyze historical vibration signals and muscle pressure from the main control module 2 to train the lightweight model and send the data to the data processor of the main control module 2.
[0062] In this technical solution, the corresponding lightweight model is trained and updated through a remote control terminal, and then distributed to the data processor of the main control module on time or as needed.
[0063] The lightweight model in the remote control terminal is encrypted and then an update package is generated. The update package is transmitted through an encrypted transmission channel, and the data processor verifies the received update package.
[0064] In this technical solution, during the distribution of the lightweight model, verification is performed at the remote control terminal during the update package generation process, the transmission process, and the data processor terminal to ensure the security of the lightweight model data distribution and prevent tampering.
[0065] More specifically, during the update package generation process at the remote control end, the model is lightweighted, meaning its size is reduced and its computational requirements are decreased, making it more suitable for running on the data processor. Subsequently, encryption is performed to prevent the model from being stolen or tampered with. In this embodiment, symmetric encryption is used, meaning the model is encrypted to generate an encrypted data packet.
[0066] During transmission, a specific encrypted transmission channel is used, such as a transport layer security protocol like TLS / SSL.
[0067] During the verification process at the data processor end, integrity verification and identity verification are usually performed. After the verification is completed, the transmitted model is decrypted to obtain an executable model, which is then installed and activated.
[0068] The technical solution of this embodiment has the following technical effects, mainly including the following four points.
[0069] 1. Utilizing the inverse piezoelectric effect, the material generates minute, high-frequency mechanical vibrations that can better massage the lower limbs. Simultaneously, intelligent block units are added, which control the vibration sequence of piezoelectric units in different areas through programming, simulating the "pumping" effect of muscle contraction and blood flow from bottom to top during walking, thereby effectively promoting blood circulation in the lower limbs and preventing the formation of deep vein thrombosis.
[0070] 2. Compared to elastic stockings, the device in this embodiment provides active massage stimulation to the muscles and can intelligently control the stimulation mode at time intervals, making it easier, more flexible and adjustable to wear.
[0071] 3. Flexible piezoelectric materials eliminate the need for bulky air pumps and complex inflation tubing, making the device lighter, easier to carry, and more suitable for long-distance travel.
[0072] 4. Quieter operation. Only slight high-frequency vibration noise, suitable for quiet environments such as airplanes, trains, and offices.
