Electrode design method, electrode manufacturing method and electrode

The invention discloses an electrode design method, a manufacturing method and an electrode. The electrode design method comprises the following steps: acquiring medical image data and a neural signal decoding demand; constructing a target cerebral cortex model according to the medical image data; according to the neural signal decoding requirement and the target cerebral cortex model, electrode parameters are determined; and determining an electrode mask file according to the electrode parameters. The technical problem that an electrode in the prior art cannot meet personalized customization requirements in different medical scenes is solved.

What the filing appears to be about, read by published rules from its title, abstract and classification codes. The claims define what a patent protects, and they are not read here.

Interface and electrodes

Everything downstream works with what the contacts pick up. Their number, size and distance from the neurons set the ceiling on the signal. The problem behind it: more contacts, closer to neurons, that still record after years in tissue that reacts to them.

Decoding

This is the step that turns brain activity into a command or a word. Its accuracy and speed are what a user experiences. The problem behind it: accuracy that holds over months without frequent recalibration, for more than one user and one task.

Why the layer matters to the field, not a judgement of this filing. A patent family shows that protection was sought. It does not show that the technology was built, is used in a product, or works in people. The whole stack

Dates as the offices published them. Office records are in the offices' own words and are a selection: refusals, lapses and withdrawals, and records that name an owner. Each concerns one member of the family, not the family as a whole, and another member in the same office may stand. Whether a patent is in force today is not assessed.
