Abstract

Abstract:

Invasive brain-computer interface (BCI) neural electrodes are pivotal components in BCI systems, but they are prone to failures such as electrical performance degradation, material fatigue, and biological rejection, which necessitate efficient and reliable testing methods. This article provides an overview of electrode detection methods in intrusive BCI, analyzing failure mechanisms, summarizing evaluation indicators, and sorting out detection methods from three aspects: electrical performance, mechanical performance, and biocompatibility. Finally, it looks forward to the development of standardization, platformization, and intelligence in invasive BCI electrode testing.

Key words: invasive BCI, neural electrodes, electrode testing
