Microwire electrode for extracting brain signals

Abstract

The invention relates to a microwire electrode for extracting brain signals. The microwire electrode comprises an electrode housing, an electrode wire array provided with multiple electrode wires installed in the electrode housing in the length direction parallel to each electrode wire in a sliding mode, a screw rod having the diameter ranging from 1 mm to 1.5 mm, installed in the electrode housing and driving the electrode wire array to move in rotation, a distance measuring device configured to detect moving distances of the screw rod and the electrode wire array and disinfected fixing glue installed outside the electrode housing. The distance measuring device is an ultrasonic distance measuring device, is provided with a wire seat and is installed on the screw rod. The electrode wire array penetrates through the disinfected fixing glue and is configured to be disinfected and fixable. The microwire electrode has the advantages that the implantation depth of each electrode wire can be independently adjusted by utilizing the screw rod, and the requirements of different electrophysiological experimenters are met.

Description

technical field [0001] The invention relates to a microwire electrode for extracting brain signals. Background technique [0002] With the development of science and technology, microwire electrodes, as a bridge between brain signals and external devices, have important applications in brain science research. The performance of microwire electrodes has an important impact on the success of experiments. The length of traditional microwire electrode wires It 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. A good electrical signal cannot be collected, and if the implantation depth of the electrode wire is adjusted as a whole, it will affect the position of other electrode wires. Contents of the invention [0003] In order to solve the above problems, the present invention provides a microwire electrode for extracting brain signals. The techni...
