Abstract

The invention relates to a magnetic compatible neural electrode and a preparation method thereof. The magnetic compatible neural electrode comprises a polyimide flexible substrate; a plurality of holes are formed in the surface of the polyimide flexible substrate; a plurality of electrodes; the plurality of electrodes are embedded in the polyimide flexible substrate; the plurality of electrodes are in one-to-one correspondence with the plurality of open pores, and part of the surface of each electrode in the plurality of electrodes is exposed to the outside through the corresponding open pores; wherein each electrode is of a titanium-gold-titanium layer structure; and the thickness of the gold metal layer in the titanium-gold-titanium layer structure is 7-10 times of the sum of the thicknesses of the two titanium metal layers in the titanium-gold-titanium layer structure. According to the magnetic compatible neural electrode, the in-vivo nuclear magnetic resonance safety requirement of the neural electrode can be met, and magnetic susceptibility artifacts caused by the electrode to magnetic resonance imaging can be reduced.

Description

technical field [0001] The present application relates to the technical field of nerve electrodes, in particular to a magnetically compatible nerve electrode and a preparation method thereof. Background technique [0002] EEG signals are important physiological electrical signals. It is an aperiodic signal consisting of oscillations of different frequencies with a characteristic frequency range and spatial distribution, related to different functional states of the brain, and representing characteristic synchronous activity on neural networks. By acquiring and analyzing EEG signals of a specific frequency, it is possible to understand the physiological state of an organism or to detect and diagnose diseases. Neural electrodes can be surgically implanted into the cerebral cortex to record electrical signals of brain neuron activity, and long-term in vivo recording of electrodes can be realized. By analyzing the electrical signals of neuron activity, the analysis and modelin...
