Method and system for switching multi-channel electrode arrays

Abstract

The invention provides a switching method and system of a multichannel electrode array. The switching method includes that a control unit transmits detecting signals to a second multichannel analog switch; the second multichannel analog switch is switched to be connected with a detector according to the detecting signals; the detector measures impedance of the electrode array when the first multichannel analog switch is in a current channel; the detector transmits the impedance to the control unit; the control unit switches the first multichannel analog switch according to the impedance. Full-automatic multichannel electrode modification and measurement and automatic switching among channels are realized, microelectrode array manufacture under the condition of unattended operation is realized, manufacturing process of neural electrode is accelerated, and the switching method is applicable to production of commercial neural microelectrode.

Description

technical field [0001] The present invention relates to the technical field of electrophysiology, in particular to the electrophysiological nerve microelectrode array technology, and specifically to a multi-channel electrode array switching method and system. Background technique [0002] At present, at least one tenth of the world's population is suffering from neuropsychiatric diseases, and the treatment burden of epilepsy, schizophrenia, depression, drug addiction, Alzheimer's disease and other neuropsychiatric diseases accounts for all 13% of diseases, more than cardiovascular disease and cancer. And with the acceleration of the pace of life and the aging of the population structure, the number of patients is still increasing. The increasing incidence of neuropsychiatric diseases worldwide not only imposes a heavy burden on patients and society, but also poses unprecedented challenges to the treatment and research of these diseases. At the same time, due to the contrad...
