Intracerebral signal acquisition device, preparation method thereof and brain-computer interface

Abstract

The invention relates to an intracerebral signal acquisition device, a preparation method thereof and a brain-computer interface. The intracerebral signal acquisition device comprises a biological silk protein substrate, a brain electrode, a first biological silk protein insulating layer, an intracranial information acquisition layer and a biological silk protein packaging layer, wherein the brainelectrode is positioned on the biological silk protein substrate and used for acquiring an electroencephalogram signal; the first biological silk protein insulating layer is positioned on the brain electrode; the intracranial information acquisition layer is positioned on the first biological silk protein insulating layer and used for acquiring intracranial temperature and intracranial pressure;and the biological silk protein packaging layer is positioned on the intracranial information acquisition layer. The intracerebral signal acquisition device has the advantages of multiple functions, capability of being implanted and degraded in vivo, capability of stably recording in vivo for a long time, high temporal-spatial resolution and the like, and can acquire the electroencephalogram signal and intracranial information, so that the problems of intracranial hemorrhage, intracranial infection and the like can be monitored in real time.

Description

technical field [0001] The present application relates to the field of brain function detection, in particular to a brain signal acquisition device, a preparation method thereof, and a brain-computer interface. Background technique [0002] In the nervous system, a large number of neurons continuously generate and transmit electrophysiological signals to realize the communication between neurons and different regions of the brain.
