Novel magnetoelectric microwire electrode

Abstract

The invention provides a novel magnetoelectric microwire electrode. The novel magnetoelectric microwire electrode comprises an electrode shell, an electrode wire array assembly, an electromagnet, a micro-spring and an indicator lamp. The electrode wire array assembly is provided with a sliding block and an electrode wire array installed on the sliding block and composed of multiple electrode wires. The sliding block is installed on the electrode shell in the direction parallel to the extension direction of each electrode wire in a sliding mode. The electromagnet is installed on the electrode shell and configured to be galvanized to generate a magnetic field or magnetic force for promoting the sliding block and the electrode wire array to move by preset distances. One end of the micro-spring is fixedly connected with the sliding block, and the other end of the micro-spring is fixedly connected with the electrode shell. The indicator lamp is installed outside the electrode shell and configured to receive leakage current luminance when the electrode shell leaks currents. The novel magnetoelectric microwire electrode has the advantages that the magnitude of the currents can be precisely controlled through the magnetic effect of the currents, and then the implantation depth of each electrode wire is adjusted.

technical field [0001] The invention relates to a novel magnetoelectric microwire electrode. Background technique [0002] With the continuous development of neuromedical technology, microwire electrode technology is also constantly improving. In order to study brain neuroscience, researchers implant microwire electrodes into specific brain regions, record brain signals generated by electrode stimulation, and process them through external equipment. Finally, it can control the machinery and help the disabled to perform some activities. The length of the electrode wires of traditional microwire electrodes is fixed, and the penetration depth of each electrode wire cannot be individually controlled.

AI Technical Summary

Problems solved by technology

The length of the electrode wires of traditional microwire electrodes is fixed, and the penetration depth of each electrode wire cannot be individually controlled. However, the electrode wires of microwire electrodes usually use electrode wire arrays. When implanted to a certain depth, there are often individual electrodes. Because the position of the electrode tip is not suitable, good electrical signals cannot be collected. If the implantation depth of the electrode wire is adjusted as a whole, it will affect the position of other electrode wires.
