Abstract:
Electrodes were expensive consumables of electrophysiological experiments. Cheap and homemademicrowire electrodes had been widely applied, but their implantation performanee was not good. To fabricatelow cost and aeceptable performanee of microwire electrode, first, the key factors affecting the longtemm re-cording performance was analyzed and the direction of the enhaneement of eleetrode was determined. The ex-isting fabrication process was improved through electrode fabrication and the eleetrode tip surface modification,and the impedanee model modified electrode was established and its properties, signal acquisition ability andbiocompatibility was systematically evaluated. The result showed that the improved electrode tip surface wassmooth and tidy, and its model was effective and its impedance decreased by 56.196 on average; record signal-to-noise ratio was higher; recording longevity reached 45 days ; biocompatibility was better. It met the re-quirement of the general eleetrophysiological experiment.
