Apparatus for Micro Electrode Array for Neural Signals Measurement and Optical Stimulus

Disclosed are a device for micro electrode array for neural signal measurement and photic simulation. According to an embodiment of the present invention, the device for micro electrode array may comprise: a substrate; a light emitting diode disposed on part of the substrate and emitting light; a first wiring connected to the light emitting diode; a first insulating layer applied on the substrate and applied on the light emitting diode and the first wiring on the substrate; an electrode disposed on part of the first insulating layer to transmit and receive neural signals; a second wiring connected to the electrode; and a second insulating layer applied on the first insulating layer excluding a partial region of the electrode.

What the filing appears to be about, read by published rules from its title, abstract and classification codes (A61B2562/16, A61B5/0059, A61B5/24). 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.

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.
