As reported by China Daily, the research team led by Chang Honglong and Ji Bowen from Northwestern Polytechnical University has recently announced a significant breakthrough in the development of a three-dimensional conical carbon-based soft cerebral cortex electrode array. This technological advancement successfully overcomes long-standing challenges in the brain-computer interface (BCI) sector, including brain tissue damage, signal attenuation, and poor biocompatibility. Furthermore, it has achieved the world's first technical verification in a space environment, paving the way for new clinical applications of BCIs and space exploration, while simultaneously demonstrating China's innovative prowess in the field of Micro-Electro-Mechanical Systems (MEMS).

Meanwhile, Neuralink, the BCI company founded by Elon Musk, has announced its intention to commence mass production of BCI devices by 2026. This announcement initially triggered a surge in A-share BCI concept stocks. However, a subsequent broad correction occurred among related stocks. According to statistics from Securities Times · Data Treasure, as of the close on February 6, the latest closing prices of 14 BCI concept stocks had declined by more than 20% from their year-to-date highs. These stocks include companies such as Haige Communications, Prete, Xiangyu Medical, Biotest, and Sanbo Brain Hospital.
