What it concerns

According to an embodiment of the present invention, a multi-channel electrode array for brain map remodeling comprises: an ultra-thin flexible substrate; a plurality of electrodes for measuring signals and applying stimulation formed on the ultra-thin flexible substrate; a plurality of track electrodes for transmitting signals, sensed by the plurality of electrodes for measuring signals and applying stimulation, to the outside or transmitting external electrical stimulation to the plurality of electrodes for measuring signals and applying stimulation; an insulating layer formed to cover the plurality of track electrodes and the ultra-thin flexible substrate while exposing the plurality of electrodes for measuring signals and applying stimulation; and a plurality of through-holes formed in a region where the plurality of electrodes for measuring signals and applying stimulation and the plurality of track electrodes are not formed and configured to penetrate the substrate and the insulating layer.

What the filing appears to be about, read by published rules from its title, abstract and classification codes (A61B2562/0209, A61B2562/04, A61B5/24, A61B5/291, A61B5/6868). The claims define what a patent protects, and they are not read here.

Why it matters

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.
Stimulation
Restoring sensation, sight or movement needs information going in, and a therapy that adapts needs to sense and stimulate at once. The problem behind it: evoking a precise, stable effect without damaging tissue or electrodes, and without blinding the recording.

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.
