Description

Technical Field

[0001] This invention relates to the field of electrode technology, and more specifically, to an electrode design method, a manufacturing method, and an electrode. Background Technology

[0002] In the field of brain-computer interfaces, intracranial cortical ECoG electrodes, as key components connecting the cerebral cortex to external devices, directly affect the acquisition and clinical decoding effectiveness of electroencephalogram (EEG) signals. Traditional ECoG electrode designs mainly fall into two categories: one is metal electrodes based on rigid materials, and the other is flexible electrodes manufactured using microelectromechanical systems (MEMS) technology. However, both types of electrodes have certain limitations, restricting their widespread application in personalized medicine scenarios.

[0003] The main problems with rigid metal electrode sheets are: fixed site layout and size: the site layout of these electrodes is usually preset and cannot be adjusted according to the brain sulci and gyri of a specific patient, which limits the adhesion between the electrode and the brain surface, thus affecting the efficiency and quality of signal acquisition; poor biocompatibility and adhesion effect: the rigidity of the metal material itself makes it difficult for the electrode to form close contact with the soft and complex brain surface, which not only leads to signal loss or absence, but may also cause immune response, and may cause tissue damage during long-term implantation, as well as a decrease in signal-to-noise ratio.

[0004] While MEMS flexible electrodes have solved the adhesion problem of rigid electrodes to some extent, they still face the following challenges: the fixation of electrode site configuration: despite the use of a flexible substrate, the size and layout of the electrode sites are still limited by the pre-designed template, making it impossible to achieve truly personalized adjustments; and the limited range of applications: for different indications, such as limb movement recovery and improvement of language disorders, signals need to be collected from different brain regions, and a single electrode design is difficult to meet diverse needs.

[0038] Figure 1 This is a flowchart illustrating an electrode design method according to an embodiment of the present invention, as shown below. Figure 1 As shown, the method includes the following steps:

[0039] Step S101: Obtain medical imaging data and neural signal decoding requirements.

[0040] Specifically, medical imaging data obtained from patients mainly includes fMRI (functional magnetic resonance imaging), MRI (magnetic resonance imaging), and CT (computed tomography) images. MRI and CT images clearly show brain structures, especially details of cortical regions, while fMRI provides the location of target brain regions, i.e., the location of functional areas. Additionally, decoding needs are obtained to determine which specific neural signals the target is to decode, such as limb movement commands or language comprehension signals.

[0041] Optionally, the requirements for neural signal decoding may also include the frequency range of the signal, the signal-to-noise ratio, and related brain region information.

[0042] Step S102: Construct a target cerebral cortex model based on medical imaging data.

[0043] Specifically, using pre-set medical image processing software, the acquired MRI and CT images are converted into three-dimensional visualization models to obtain a target cerebral cortex model, accurately presenting the geometric features and surface morphology of the patient's cerebral cortex.

[0044] Optionally, when constructing the target cerebral cortex model, fMRI (functional magnetic resonance imaging) data is also used to mark the target functional areas on the cerebral cortex model. These areas are the focus of subsequent electrode design to ensure that the electrodes accurately cover the target areas.

[0045] Understandably, the constructed target cerebral cortex model includes the target functional area.

[0046] Step S103: Determine electrode parameters based on neural signal decoding requirements and the target cerebral cortex model.

[0047] Specifically, electrode parameters include electrode size and layout. Based on the characteristics of the target brain region in the target cerebral cortex model and decoding requirements, the size (including the size and shape of the electrode sites), layout (the spacing and arrangement between electrodes), and density (the number of electrodes per unit area) of the electrodes are determined. This step is highly personalized and aims to optimize signal acquisition efficiency and signal-to-noise ratio.

[0048] Optionally, when determining electrode parameters, appropriate electrode materials may be selected based on signal type and patient safety considerations.

[0049] Step S104: Determine the electrode mask file based on the electrode parameters.

[0050] Specifically, after determining the electrode parameters, a mask is designed using preset mask design software. A mask is a template used for patterning during MEMS manufacturing, determining the shape and layout of the electrodes. Mask file output: The completed mask design is output in a specific format (such as GDSII) to form an electrode mask file.

[0051] It should be noted that the mask design must cover all electrode sites, interconnects, and necessary control circuitry. Each part must be precise to the micrometer level to ensure the accuracy of the photolithography steps.

[0052] In this embodiment of the invention, an electrode design method is provided, comprising: acquiring medical imaging data and neural signal decoding requirements; constructing a target cerebral cortex model based on the medical imaging data; determining electrode parameters based on the neural signal decoding requirements and the target cerebral cortex model; and determining an electrode mask file based on the electrode parameters. This invention constructs a target cerebral cortex model using medical imaging data, taking into account the medical imaging data of actual patients, resulting in a targeted model. Furthermore, after constructing the target cerebral cortex model, it also considers neural signal decoding requirements. Electrode parameters are determined under the combined effect of the target cerebral cortex model and neural signal decoding requirements, thereby achieving personalized customization of the electrode design process for different patients and different neural signal decoding requirements. This solves the technical problem that electrodes in the prior art cannot meet the personalized customization needs of different medical scenarios.

[0053] Optionally, the medical imaging data includes structural images and functional images of the cerebral cortex. In step S102 above, constructing a target cerebral cortex model based on the medical imaging data may include the following steps:

[0054] Step S1021: Add the functional image of the cerebral cortex to the structural image of the cerebral cortex to obtain the target image, wherein the target image includes the structural features and functional area features of the cerebral cortex.

[0055] Specifically, structural images of the cerebral cortex (such as high-resolution MRI scans) are overlaid and fused with functional images (such as functional magnetic resonance imaging (fMRI) and positron emission tomography (PET). Structural images provide the brain's anatomical structure, while functional images reveal the activity of brain regions during specific tasks. During the fusion process, ensuring precise alignment between the two sets of images is crucial. Image processing techniques can be used to adjust the spatial positioning of the images, ensuring accurate matching of structural features and functional area features within the target image. The fused target image includes structural features of the cerebral cortex (such as sulci and gyri, and the boundary between white and gray matter) and functional areas (such as the motor cortex, sensory cortex, and language cortex).

[0056] Step S1022: Determine the cerebral cortex model based on the target image.

[0057] For example, a 3D reconstruction algorithm is used to transform a 2D target image into a 3D model of the cerebral cortex. The software constructs the 3D geometry of the cerebral cortex, including details such as sulci, folds, and wrinkles, based on the grayscale values ​​or labeling information in the target image. Simultaneously, functional areas are precisely mapped onto the 3D model based on the functional area features in the target image.

[0058] Optionally, in some embodiments of the present invention, model correction and optimization are included, based on clinical experience and anatomical knowledge, to correct the reconstructed model, for example, by filling gaps in the image and smoothing unnatural surfaces, to ensure the accuracy of the model and its usability for subsequent steps.

[0059] Optionally, in some embodiments of the present invention, the completed cerebral cortex model is validated by comparing it with the original medical imaging data to confirm the accuracy of the model.

[0060] Optionally, in step S103 above, determining the electrode parameters based on the neural signal decoding requirements and the target cerebral cortex model may include the following steps:

[0061] Step S1031: Determine the type of neural signal requirement based on the neural signal decoding requirements.

[0062] Specifically, the need for decoding neural signals can include action potentials, local field potentials, electromyography signals, etc., depending on the application of the target therapy, such as motor control assistance, pain management, epilepsy monitoring, etc. Based on the type of need, the required type of decoded neural signal (including but not limited to frequency range, amplitude characteristics, and spatiotemporal pattern of the signal) is determined. Different signal types have different requirements for the size, shape, and density of electrodes.

[0063] Step S1032: Determine the initial parameters according to the type of neural signal demand.

[0064] For example, initial parameters include electrode site size and site density. For high-frequency, high-amplitude neural signals, a larger electrode contact area is required to acquire the relevant signals; while for low-frequency signals, the electrode size needs to be reduced to improve spatial resolution. At the same time, considering signal transmission, the electrode thickness and the size of the transmission wires also need to be set.

[0065] The electrode array layout is designed based on the spatial distribution of decoding requirements. For areas requiring high-resolution signal acquisition, the electrode spacing should be smaller and the density higher; while for areas with less stringent signal acquisition requirements or a wider range of signal sources, the electrode spacing can be appropriately increased to reduce potential signal crosstalk.

[0066] Based on considerations of signal characteristics and patient safety, appropriate conductive materials are selected. For example, highly conductive and chemically stable materials such as graphene, titanium, platinum, or gold are often used as electrode site materials that come into direct contact with brain tissue, while insulating and stable materials such as parylene and polyimide (PI) are used as the main electrode materials to improve the biocompatibility of the electrode with brain tissue and the purity of the signal.

[0067] Step S1033: Optimize the initial parameters based on the target cerebral cortex model to obtain electrode parameters.

[0068] Specifically, the initial parameters obtained in step S1032 are aligned with the target cerebral cortex model to ensure that the electrode array layout accurately covers the functional areas identified in the model, while avoiding unnecessary interference with brain regions. Based on the target cerebral cortex model, the electrode shape is adjusted to better adapt to the curved structure of the cerebral cortex, the electrode spacing and density are optimized to adapt to changes in neural signal intensity in different regions, and further screening of electrode materials is conducted to ensure that good signal transmission is maintained while minimizing the impact on brain tissue.

[0069] Understandably, through the above steps, it is possible to accurately determine various parameters of the electrodes based on specific neural signal decoding needs and individualized three-dimensional models of the patient's cerebral cortex.

[0070] Optionally, the initial parameters include electrode site size and site density. In step S1033 above, optimizing the initial parameters based on the target cerebral cortex model to obtain the electrode parameters may include the following steps:

[0071] Step S1033a: Based on the target cerebral cortex model, determine the functional characteristics of the functional areas in the target cerebral cortex.

[0072] Specifically, by using a constructed model of the target cerebral cortex and the marked functional areas within the model, combined with the patient's specific fMRI data, the characteristics of each functional area are analyzed. This includes, but is not limited to, the activity level of the functional area, the specific neural functions it is responsible for, and its interaction and connection patterns with other functional areas.

[0073] Step S1033b: Based on the functional characteristics, the electrode site size and site density are optimized to obtain the electrode parameters.

[0074] Specifically, based on the characteristics of the functional area, the type of neural signals generated or received in that area and its main frequency range can be determined.

[0075] The size of the electrode sites is adjusted according to the signal type and frequency range of each functional area. For high-frequency signals, larger electrode sites are needed to acquire the relevant signals; for low-frequency signals, smaller electrode sites are needed to improve spatial resolution.

[0076] Ensure that the size of the electrode sites matches the micro-topography of the cerebral cortex, such as adapting to the depth and width of the sulci and gyri, to guarantee good mechanical contact and signal transmission.

[0077] For areas with dense functionalities or requiring high-resolution signal acquisition, increasing the density of electrode sites can capture more detailed information and improve decoding accuracy.

[0078] At the same time, considering the biocompatibility of brain tissue and the stability of long-term implantation, it is not advisable to use high-density configuration in all areas. It is necessary to balance signal crosstalk and decoding requirements, as well as electrode adhesion and patient safety and comfort.

[0079] Understandably, based on the above steps, the size and density of electrode sites can be precisely adjusted according to the functional characteristics of a patient's specific cerebral cortex model, thereby obtaining a highly customized set of electrode parameters. These parameters not only maximize the efficiency of neural signal acquisition and decoding but also ensure the safety of electrode implantation and the individual patient's comfort.

[0080] Optionally, the initial parameters include electrode shape and electrode size. In step S1033 above, optimizing the initial parameters based on the target cerebral cortex model to obtain electrode parameters may include the following steps:

[0081] Step S1033c: Based on the target cerebral cortex model, determine the structural features of the target cerebral cortex.

[0082] For example, for a three-dimensional target cerebral cortex model, the structural features of the cerebral cortex most relevant to the decoding requirements of neural signals are identified and confirmed, and these features are used as the basis for subsequent parameter optimization. These features include, for example, the curvature, thickness, distribution of sulci and gyri of the cerebral cortex, and the geometry and location of specific functional areas.

[0083] During feature extraction, computer vision and machine learning algorithms are used to extract specific numerical values ​​or descriptions of the aforementioned structural features from the model. For example, edge detection algorithms are used to identify the boundaries of grooves and troughs; morphological analysis is used to quantify curvature and thickness; and region segmentation techniques are used to determine the size and shape of functional areas.

[0084] In step S1333d, the electrode shape and size are optimized based on the structural characteristics to obtain the electrode parameters.

[0085] Specifically, based on the curvature and geometry of the cerebral cortex, the shape of the electrodes is optimized to ensure that they fit closely to the cortical surface, reducing mechanical stress and protecting brain tissue. For example, smaller electrode shapes are needed for areas with greater curvature, while larger electrode shapes can be chosen to cover a wider area for flat or open regions. Electrode sizes are adjusted according to the structural features in the target cerebral cortex model to ensure that electrode sites cover all key areas while avoiding interference between electrodes.

[0086] Optionally, in step S103, the electrode parameters are determined according to the neural signal decoding requirements and the target cerebral cortex model, including: inputting the neural signal decoding requirements and the target cerebral cortex model into a pre-constructed electrode parameter determination model, and using the electrode parameter determination model to determine the electrode parameters, wherein the electrode parameter determination model includes the correspondence between the neural signal decoding requirements, the target cerebral cortex model and the electrode parameters.

[0087] For example, a large amount of known neural signal decoding requirements, cerebral cortex model data, and corresponding electrode parameter settings are collected.

[0088] Feature extraction: Extract key features from the cerebral cortex model, such as the curvature of the cortex, the sulcus, and the location of functional areas; at the same time, extract key elements such as signal type, frequency range, and decoding accuracy requirements from the neural signal decoding needs.

[0089] Model training: Machine learning algorithms (such as support vector machines, neural networks, decision trees, etc.) are used to construct a model for determining electrode parameters. The above features are used as inputs, and the electrode parameters (including electrode size, site density, shape, etc.) are used as outputs to train the model and establish the correlation between them.

[0090] The specific neural signal decoding requirements are input into the model, including the type of signal to be decoded (e.g., motor, sensory, and language signals), the frequency range of the signals to be acquired, and the required decoding accuracy. Simultaneously, the constructed 3D model data of the target cerebral cortex is used as another set of inputs, including the geometry of the cerebral cortex, the precise location and size of each functional area, and other information. The electrode parameter determination model, based on the input decoding requirements and the cerebral cortex model, automatically analyzes the correlation between the two and dynamically adjusts and optimizes the electrode parameters through internal algorithms and a pre-trained model.

[0091] The model outputs a series of electrode parameters, including but not limited to the size of the electrode sites, the density and distribution between sites, the selection of electrode materials, and the overall layout of the electrode array. These parameters are based on the model's deep understanding of input requirements and brain structure, and aim to maximize the acquisition quality and decoding efficiency of neural signals.

[0092] Optionally, the electrode design method further includes: using preset simulation software to simulate the interaction between the electrode corresponding to the electrode parameters and the target cerebral cortex and to acquire EEG signals; determining the parameter validity of the electrode parameters based on the EEG signals; and iteratively optimizing the electrode parameter determination model based on the parameter validity.

[0093] For example, based on the electrode parameters optimized in step S103, such as electrode site size, site density, shape, and material properties, a complete electrode model is established in the simulation software. The target cerebral cortex model obtained in step S102 is imported into the simulation environment to ensure the accuracy and completeness of the model. The simulation boundary conditions and physical parameters are set, such as signal source type, frequency, cerebral cortex conductivity, dielectric constant, etc., and then the simulation program is run to simulate the process of electrodes collecting EEG signals on the target cerebral cortex, observing and recording key information such as signal quality and the contact state between the electrodes and the cerebral cortex.

[0094] The EEG signals obtained from the simulation were analyzed to evaluate whether key indicators such as signal-to-noise ratio, frequency response, and spatial resolution met the requirements for neural signal decoding. The quality of the signal directly affects the accuracy of the decoding.

[0095] Based on the signal quality analysis results, evaluate the effectiveness of the current electrode parameter settings. If the signal quality does not meet expectations, further analyze which parameters are problematic, such as electrode size, density, or material selection.

[0096] The validity evaluation results of the parameters determined in the above steps are fed back to the electrode parameter determination model as input data for model optimization.

[0097] Based on the feedback data, adjust the model's algorithm framework or parameter settings, including updating weights, introducing new feature variables, changing the learning rate, etc., and then retrain the model to make it more accurate in predicting electrode parameters.

[0107] Optionally, the preset electrode manufacturing process is a microelectromechanical system (MEMS) manufacturing process.

[0108] In embodiments of the present invention, the above-described electrode manufacturing method is implemented as follows:

[0109] Preparations before manufacturing:

[0110] Mask file generation: Based on the determined electrode parameters, the software generates an electrode mask file, which guides the subsequent micro-nano fabrication process.

[0111] Step 1: Substrate processing:

[0112] Substrate selection: Select a substrate material with excellent biocompatibility and flexibility, such as polyimide (PI), which can adapt to the complex topography of the cerebral cortex.

[0113] Substrate preparation: The PI substrate is pretreated, including cleaning and surface activation, to ensure the adhesion of subsequent materials and the stability of the electrodes.

[0114] For example, the PI layer thickness is 2-5 μm.

[0115] Step 2: Metal layer deposition and patterning:

[0116] Metal sputtering: A Cr / Au (chromium / gold) alloy layer with a thickness of approximately 300 nm is uniformly deposited on the PI substrate using metal sputtering technology. Cr serves as the adhesion layer, while Au provides good conductivity and biocompatibility.

[0117] Photolithography patterning: Using photolithography, the shape and size of the electrode sites are defined based on the mask file. This step requires extremely high precision to ensure that each electrode site is accurately placed in the predetermined position.

[0118] Step 3: Preparation of insulating layer at electrode sites:

[0119] Insulating layer deposition: By spin-coating a PI layer over the metal electrode layer, an insulating layer is formed to protect the electrode from external interference and ensure good contact between the electrode and the cerebral cortex.

[0120] RIE etching: Reactive ion etching (RIE) technology is used to precisely create holes in the PI insulating layer to expose electrode sites, but the surrounding insulating layer is preserved to prevent short circuits or corrosion of the electrodes by biological fluids.

[0121] Step 4: Packaging and post-processing of the electrode array:

[0122] Flexible encapsulation: After the above procedures are completed, the entire electrode array needs to be flexibly encapsulated to ensure that the electrode array can maintain the necessary flexibility and mechanical strength when implanted into the cerebral cortex, thereby reducing damage to brain tissue.

[0123] Electrode array testing: Perform electrical performance tests on the electrode array to check the connectivity between electrodes, the impedance values ​​of the electrodes, and the overall signal transmission capability.

[0124] Step 5: Electrode release and cleaning:

[0125] Electrode release: Through a specific release process, the formed electrode array is separated from the substrate, making it an independent flexible electrode.

[0126] Thorough cleaning: The separated flexible electrodes are cleaned to remove any residual chemicals or impurities to ensure the safety and reliability of the electrodes when implanted in the brain.
