Abstract

ObjectiveTo explore the main path of technology development based on the patent citation network in the field of brain-computer interface (BCI). Methods The patent citation network in the field of brain-computer interface was constructed, and the traversal weights were calculated by the search path link count. The global main path, global key-route main path, local forward main path, local backward main path and local key-route main path were analyzed by two path search methods, global search and local search, so as to explore the technological development trajectory in this field of BCI. Results There were 15519 patent applications in the field of BCI, including 140691 patent citations, and the number of patent applications increased year by year. Technology development focused on neural stimulation and regulation technology, neural signal acquisition and processing technology, BCI hardware technology and other directions. The main path analysis showed that the technical theme was electrical stimulation as the core, emphasizing precise neural regulation and personalized treatment. The number of patents on the global main path was the largest (16), including 2 technical routes, and the global key-route main path was consistent with the global main path. There were 14 patents on the local forward main path, including 1 technical route, and the local key-route main path was consistent with the local forward main path. There were 10 patents on the local backward main path, including 1 technical route. Conclusion Through the main path analysis of patents in the field of BCI, this study identifies the technological development trajectory and provides information support for the research and development of BCI from the perspective of information science.
