Embodiment 1

[0030] combine figure 1 and figure 2 , the present embodiment provides a neural interface, which includes at least one microneedle body 1 and a flexible base 2, and the microneedle body 1 is bound on the flexible base 2. Wherein, at least one body electrode point is arranged on the microneedle body 1, and the body electrode point is used for collecting nerve signals.

[0031] Wherein, the flexible substrate 2 is made of flexible materials, wherein the flexible materials include silica gel, PDMS, polyimide or bacterial cellulose.

[0032] In an optional embodiment, the flexible base 2 has a hollowed out part to improve the flexibility of the flexible base 2 .

[0033] In this embodiment, the flexible base 2 is circular, elliptical, polygonal or fan-shaped.

[0034] In an actual application scenario, the number of the microneedles 1 is multiple, and the plurality of microneedles 1 are arranged and formed along a preset rule to form a microneedle array on the flexible substra...

Embodiment 2

[0042] Such as figure 1 As shown, the present application provides a neural interface, including at least one microneedle body 1 and a flexible base 2, and the microneedle body 1 is bound on the flexible base 2.

[0043] In an optional embodiment, the flexible substrate 2 is disc-shaped, and when there are a plurality of microneedles 1, the plurality of microneedles 1 can be arranged along the diameter of the disc to form a microneedle array, Wherein, along the direction away from the geometric center of the flexible substrate, the distribution of the microneedles 1 is gradually sparse. Since the flexible base 2 is made of flexible materials, the flexible base 2 can be deformed. In the actual use process, an external force can be applied to the flexible base according to the specific structure of the target position, so that the flexible base is deformed to ensure that the flexible base and the target position are formed. Good attachment can increase the implantation depth of...

Embodiment 3

[0050] In this embodiment, the application provides another neural interface, which can be used as an artificial retina to enable people with retinal damage or detachment to have visual perception function. The artificial retinal microneedle array structure made of flexible substrate 2 does not need to order the binding material of the microneedle body 1 according to the size of the eyeballs of the visually impaired in advance. The flexible substrate 2 is easy to deform, which can make the microneedle The body 1 is inserted into the nerve tissue of the retina, making the back of the flexible base 2 concave to form a hemispherical shape, forming a good fit with the eyeball, and reducing the friction sensation caused by the rigid binding material.

[0051] In one of the optional embodiments, the disc-shaped flexible base 2 has a hollowed out part, that is, a part that does not need to bind the microneedle body 1, and the hollowed out part can be set according to the structure of ...

Abstract

The invention belongs to the technical field of nerve interfaces, and provides a nerve interface which comprises at least one microneedle body and a flexible substrate, and the microneedle body is bound on the flexible substrate. The invention provides a nerve interface which comprises at least one micro-needle body and a flexible substrate, the micro-needle body is bound on the flexible substrate, the flexible substrate can deform under the action of external force and can be better attached to the surface of a meninx, the micro-needle can better avoid brain blood vessels, implantable injury is reduced, and the nerve interface can be applied to the brain. And meanwhile, a single nerve action potential can be read out.

Description

technical field [0001] The present application relates to the technical field of neural interfaces, in particular to a neural interface. Background technique [0002] A connection path can be established between a human (or animal) and an external device through a neural interface. In the case of a one-way neural interface, the computer either receives information from the nerve cells or sends signals to the brain (such as video reconstruction), but not both. A bidirectional neural interface, on the other hand, allows two-way information exchange between the brain and external devices. [0003] In the neural interface, it is often necessary to obtain neuron signals through the neural interface, and the substrate of the neural interface cannot be well attached to the surface of the pia mater. Contents of the invention [0004] The main purpose of this application is to propose a neural interface, the flexible substrate can be deformed under the action of external force, w...
