[0043] Currently, biomedical sensing technology plays an important role in disease diagnosis, treatment monitoring and physiological research, in which implantable electrodes can be used to monitor physiological information such as neural signals and muscle activity in real time. Among them, flexible electrodes have good flexibility and biocompatibility, can better adapt to the movement of tissues, reduce tissue damage, and are widely used.

[0044] In related technologies, the material of the flexible electrode usually adopts a low modulus polymer substrate and a soft conductive material to realize good flexibility and biocompatibility. However, it is found in actual application that in invasive applications, the flexible electrode needs to penetrate the tissue, and insufficient hardness will cause the flexible electrode to break or deform, affecting the stability of signal acquisition.

[0047] The following describes the specific implementation of the embodiment of the present application in detail with reference to the accompanying drawings. First, a method for enhancing the hardness of a flexible electrode provided in the embodiment of the present application is described with reference to the accompanying drawings.

[0048] Please refer to Figure 1 , Figure 1 1 is a schematic diagram of an implementation environment of a method for enhancing the hardness of a flexible electrode provided by an embodiment of the present application. In this implementation environment, the main software and hardware entities involved include a terminal processor 110 and a server 120.

[0049] Specifically, the terminal processor 110 may be installed with a control program for the flexible electrode hardness enhancement method, and the server 120 is the backend server for the control program. The terminal processor 110 and the backend server 120 are in communication with each other. The flexible electrode hardness enhancement method provided in the embodiments of the present application can be executed on the terminal processor 110 side.

[0050] The server 120 can be a stand-alone physical server, a server cluster or a distributed system composed of multiple physical servers, a cloud server providing cloud services, cloud database, cloud computing, cloud function, cloud storage, network service, cloud communication, middleware service, domain name service, security service, CDN (Content Delivery Network), and basic cloud computing services such as big data and artificial intelligence platform.

[0051] In addition, the server 120 can also be a node server in a blockchain network.

[0052] The terminal processor 110 and the server 120 can establish a communication connection through a wireless network. The wireless network uses standard communication technology and / or protocol, and the network can be set as the Internet, or any other network, for example, including but not limited to a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), a mobile or wireless network, a private network or a virtual private network, or any combination thereof. In addition, the above-mentioned software and hardware subjects can use the same communication connection mode or different communication connection modes, and the application does not make specific limitations.

[0053] Of course, it can be understood that Figure 1 The implementation environment in the above Figure 1 The software and hardware environment shown in the above is not limited in the application.

[0054] As Figure 2 As Figure 2 is a flowchart of a flexible electrode hardness enhancement method provided by the embodiments of the application, and specifically includes but is not limited to steps 100 to 300.

[0055] Step 100, obtaining a flexible electrode to be implanted.

[0056] In the embodiments of the present application, flexible electrodes of different material types and different sizes and lengths can be selected according to the morphology of the target tissue. Among them, flexible electrodes refer to electrode materials or devices that can maintain conductive properties and structural integrity under deformation conditions such as bending, stretching, and torsion. Flexible electrodes are key biomedical sensors and are widely used in electrophysiological signal acquisition, such as electrocardiogram (ECG), electromyogram (EMG), electroencephalogram (EEG), etc. Its electrode materials include conductive materials (such as metals, carbon materials, polymers) and flexible substrates (such as polydimethylsiloxane (PDMS), polyimide), etc., and the preparation process mainly includes micromachining or screen printing process, etc. The design of flexible electrodes is intended to adapt to the complex structure in human tissue, reduce the mechanical stimulation of electrodes to living organisms, and achieve long-term stable signal recording.

[0057] Furthermore, a flexible electrode to be implanted that meets the requirements can be selected based on whether it serves as a sensing electrode for recording physiological signals or as an electrical stimulation electrode for applying electrical stimulation signals.

[0058] Step 200: Modify the polymer coating on the flexible electrode to be implanted to obtain a flexible electrode with enhanced hardness.

[0059] In an embodiment of the present application, by modifying the polymer coating for the flexible electrode to be implanted, the mechanical strength of the electrode is enhanced without sacrificing flexibility, ensuring the rigidity of the flexible electrode during implantation and application, as well as its long-term stability in a complex physiological environment, so that it can smoothly penetrate the high-modulus cortex and be implanted into the subcutaneous tissue.

[0060] In practical applications, after the flexible electrode is implanted into biological tissue, the polymer coating modified on the surface of the flexible electrode can absorb water and dissolve, allowing the flexible electrode to restore its flexibility and biocompatibility, meeting the operational requirements of the flexible electrode.

[0061] Step 300: Using the flexible electrode with enhanced hardness, complete the implantation process of the flexible electrode.

[0062] In the embodiment of the present application, by utilizing a flexible electrode with enhanced hardness, the mechanical hardness of the flexible electrode during implantation can be significantly improved, so that it can be successfully implanted into the subcutaneous tissue, avoiding the situation where the electrode is broken or deformed due to insufficient hardness, and helping to complete the implantation process of the flexible electrode.

[0063] For example, please refer to Figure 3 , Figure 3 This is a schematic diagram of a modified flexible electrode provided in an embodiment of the present application. By modifying a polymer coating on the surface of the flexible electrode, a flexible electrode with enhanced hardness can be obtained.

[0064] Currently, flexible electrodes primarily utilize low-modulus polymer substrates and soft conductive materials such as PDMS, carbon nanotubes, and graphene. In device design, porous structures, kirigami structures, or fractal designs further enhance the flexibility and adaptability of electrodes, enabling them to better adapt to the dynamic changes in human tissue and reduce mechanical stimulation. However, in invasive applications, electrodes need to penetrate tissue and remain in place for extended periods. Insufficient rigidity can lead to electrode breakage or deformation, impacting signal acquisition stability. This is primarily due to the significant difference between the modulus of existing materials and that of human tissue.

[0065] Therefore, this application significantly improves the mechanical hardness of the flexible electrode during the implantation process by modifying the flexible electrode with a polymer coating, so that it can be successfully implanted into the subcutaneous tissue. At the same time, after implantation into the tissue, the polymer coating can be washed and dissolved in water, so that the flexible electrode can maintain good flexibility and biocompatibility after implantation into the tissue, avoiding the situation where the hardness of the flexible electrode is too high and affects signal acquisition.

[0066] Specifically, as an optional embodiment, modifying the polymer coating on the flexible electrode to be implanted to obtain a flexible electrode with enhanced hardness includes:

[0067] Obtaining the prepared hardness-enhancing coating solution;

[0068] coating the surface of the flexible electrode to be implanted with the hardness-enhancing coating solution;

[0069] The flexible electrode is dried at room temperature, thereby completing the modification of the polymer coating on the flexible electrode to be implanted, and obtaining a flexible electrode with enhanced hardness.

[0070] In an embodiment of the present application, the hardness-enhancing coating solution can be obtained after preparation, and evenly coated on the surface of the flexible electrode to be implanted, and dried at room temperature for a certain period of time, thereby completing the modification of the polymer coating on the flexible electrode to be implanted and obtaining a flexible electrode with enhanced hardness.

[0071] In practical applications, when obtaining the prepared hardness-enhancing coating solution, the polymer substance can be dissolved in water at a target temperature to form and obtain the prepared hardness-enhancing coating solution.

[0072] Among them, different types of polymer substances such as gelatin, polyvinyl pyrrolidone and polyvinyl alcohol can be used as raw materials to prepare the hardness-enhancing coating solution.

[0073] For example, taking gelatin as an example, 1 g of gelatin powder can be dissolved in 4 mL of deionized water and heated in an oven at 55° C. for one hour to form and prepare a gelatin solution as a hardness-enhancing coating solution.

[0074] In practical applications, the hardness of the polymer coating can be dynamically adjusted by adjusting the polymer material and the preparation ratio. In addition, the hardening degree of the flexible electrode can be adjusted by adjusting the average molecular weight of the material.

[0075] Furthermore, the hardness-enhancing coating solution is evenly modified on the surface of the flexible electrode by multiple immersion coatings (for example, five times), and the flexible electrode is dried and cooled at room temperature, thereby obtaining a flexible electrode with enhanced hardness.

[0076] Among them, the flexible electrode can be an insulated platinum wire, a PI single-channel electrode, or a PI multi-channel electrode, which can effectively improve the usability of the flexible electrode.

[0077] Optionally, the drying time of the flexible electrode is positively correlated with the electrode diameter of the flexible electrode.

[0078] In an embodiment of the present application, after the flexible electrode is coated with the hardness-enhancing coating solution, the drying time at room temperature is positively correlated with the electrode diameter of the flexible electrode. The longer the electrode diameter of the flexible electrode, the longer the corresponding drying time.

[0079] For example, when the diameter of the flexible electrode is 50 μm, the drying time at room temperature can be set to two hours; when the diameter of the flexible electrode is 100 μm, the drying time at room temperature can be set to four hours; when the diameter of the flexible electrode is 200 μm, the drying time at room temperature can be set to six hours.

[0080] Of course, it can be understood that the above embodiments are only some optional application scenarios of the drying time settings provided in the embodiments of this application. The actual application is not fixed to the above embodiments, and this application does not impose specific restrictions on this.

[0081] Specifically, as an optional implementation manner, the use of the flexible electrode with enhanced hardness to complete the implantation process of the flexible electrode includes:

[0082] applying a radio frequency voltage to the flexible electrode with enhanced hardness to obtain a flexible electrode with a localized radio frequency electric field;

[0083] The flexible electrode with the localized radio frequency electric field is used to complete the implantation process of the flexible electrode.

[0084] In an embodiment of the present application, by applying an RF voltage to the flexible electrode with enhanced hardness, the RF voltage will converge at the tip of the flexible electrode, thereby forming a localized RF electric field at the tip of the flexible electrode, thereby obtaining a flexible electrode with a localized RF electric field.

[0085] In practical applications, by applying a radio frequency voltage to the flexible electrode and forming a localized radio frequency electric field at the tip of the flexible electrode, the water molecules in the tissue cells can be induced to vibrate rapidly by the radio frequency alternating voltage to generate resonance, heat is released in the tissue and cell damage occurs, forming a small channel for the insertion of the flexible electrode, and then the flexible electrode is conveniently inserted into the skin tissue under the action of a low mechanical force, and the implantation process of the flexible electrode is completed.

[0086] Optionally, the radio frequency voltage is applied to the flexible electrode with enhanced hardness to obtain a flexible electrode with a localized radio frequency electric field.

[0087] The radio frequency parameters of the radio frequency generator are determined; wherein the flexible electrode with enhanced hardness is connected to the working electrode of the radio frequency generator;

[0088] By controlling the operation mode of the radio frequency generator, the radio frequency voltage is transmitted to the flexible electrode with enhanced hardness by the working electrode, so that the radio frequency voltage is applied to the flexible electrode with enhanced hardness to obtain a flexible electrode with a localized radio frequency electric field.

[0089] In the embodiments of the present application, the radio frequency generator can be used as a source of radio frequency voltage, and the flexible electrode with enhanced hardness is connected to the working electrode of the radio frequency generator, so that by controlling the operation mode of the radio frequency generator, the radio frequency voltage is transmitted to the flexible electrode with enhanced hardness by the working electrode, so that the radio frequency voltage is applied to the flexible electrode with enhanced hardness to obtain a flexible electrode with a localized radio frequency electric field.

[0090] In practical applications, before starting the radio frequency generator, the radio frequency parameters of the radio frequency generator can be determined in advance, including but not limited to radio frequency power, radio frequency frequency, pulse width and duty cycle. By modulating the preset radio frequency parameters and adjusting the operation mode of the radio frequency generator, the intensity of the localized radio frequency electric field at the tip of the flexible electrode can be further controlled.

[0091] Further, the radio frequency generator can also be provided with a neutral electrode. During the implantation process of the flexible electrode, the neutral electrode can be directly attached to the surface of the biological tissue. When the radio frequency effect is applied to the working electrode, the current is transmitted from the working electrode to the flexible electrode into the tissue, and then returned to the radio frequency generator through the neutral electrode, forming a complete current loop. The neutral electrode can be a high-frequency electrotome negative plate.

[0092] Specifically, as an optional embodiment, the method further comprises:

[0093] The hardness coefficients of the flexible electrode before the implantation process is completed and the flexible electrode after the implantation process is completed are determined by wind power test.

[0094] In the examples of this application, please refer to Figure 4 , Figure 4 This is a structural diagram of a wind testing system provided in an embodiment of the present application. The wind testing system can be used to perform wind tests on flexible electrodes in an initial state, flexible electrodes before implantation after hardness enhancement, and flexible electrodes after implantation, thereby obtaining the hardness coefficient of each flexible electrode.

[0095] For example, Figure 4 As shown, the flexible electrode in the initial state, the flexible electrode before implantation after hardness enhancement, and the flexible electrode after implantation are obtained respectively, and fixed to the test position in turn for wind force testing. First, the initial position information of the flexible electrode is obtained by a shooting device, and then a fixed wind speed is applied to the flexible electrode by a fan, and the bending condition of the flexible electrode is recorded by a shooting device. Then, the initial position information of the flexible electrode and the bending condition under the action of wind speed are analyzed and compared by the testing device to determine the bending angle of the flexible electrode, thereby determining the hardness coefficient of the flexible electrode in each state.

[0096] In practical applications, by comparing the bending angle of the flexible electrode in the initial state with the bending angle of the flexible electrode before implantation after hardness enhancement, it can be determined that the hardness of the flexible electrode can be effectively improved by modifying the polymer coating. By comparing the difference in bending angles of the flexible electrode before implantation and the flexible electrode after implantation, it can be determined that after the flexible electrode is implanted into biological tissue, the polymer coating can absorb water and dissolve, so that the flexible electrode can restore its flexibility and biocompatibility, so as to complete subsequent tasks such as collecting living electrical signals and applying electrical stimulation signals.
