Microfilament device and preparation method of microfilament device

The invention provides a microfilament device and a preparation method of the microfilament device, and the microfilament device comprises a microfilament electrode which comprises a transmission part and a plurality of microfilament structures connected to one side of the transmission part, and each microfilament structure is provided with an electrode site; the temporary supporting structure is located on the surface of one side of the microwire electrode and makes contact with each microwire structure, the part, making contact with the temporary supporting structure, of each microwire structure is a first electrode section, each microwire structure is further provided with a second electrode section connected to the end, away from the transmission part, of the first electrode section, and the second electrode section is provided with an electrode site. By applying the technical scheme of the invention, the problems of low preparation yield, complicated operation and poor reliability of the multi-microfilament device can be solved.

The abstract as published by the patent office, from CN122464390A. It describes the invention; it is not a statement of what is protected.

What the filing appears to be about, read by published rules from its title, abstract and classification codes (B81B1/008, B81C1/00111). 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
