Abstract

Disclosed is a brain-computer interface with gel microneedle brain electrodes. The brain-computer interface comprises a plurality of microneedle electrodes (1), wherein each of the microneedle electrodes (1) comprises a plurality of microneedles (11); each microneedle (11) comprises a gel electrolyte (111) and a columnar electrode (112); and the columnar electrode (112) passes through the interiorof the corresponding gel electrolyte (111) and is exposed from the tip of the corresponding microneedle (11). The brain-computer interface with the gel microneedle brain electrodes is low in impedance and capable of rapidly and accurately collecting electroencephalogram signals.

Description

technical field [0001] The disclosure relates to the technical field of medical devices, in particular to a brain-computer interface with gel microneedle brain electrodes. Background technique [0002] As the most direct and effective tool for human-computer interaction, brain-computer interface has always attracted much attention. Non-invasive brain-computer interfaces based on EEG (electroencephalogram) are widely used. [0003] The current EEG brain-computer interface has the following disadvantages: [0004] First, the monitoring part of the entire brain-computer interface is bulky, poor in portability and wearability, and cannot be worn for a long time without affecting daily life. [0005] Second, the test accuracy is not high, the spatial resolution is low, and it is impossible to complete high-speed and accurate human-computer information interaction and mind control. [0006] Third, the Young's modulus of the preparation material of the electrode does not match t...
