BrainStep Medical, a Shanghai-based brain-computer interface (BCI) company founded by two post-90s entrepreneurs, has emerged as the second firm globally to advance into the registration clinical phase of invasive BCI within an impressive five years of its inception. Recently, BrainStep Medical successfully completed an implantation surgery, enabling a patient with amputated limbs to navigate the internet and play games solely through their thoughts. Numerous product performance metrics of BrainStep Medical surpass those of Musk's Neuralink. By utilizing high-polymer as the substrate and employing micro-nano processing technology to shrink electrode size down to the cellular level, BrainStep Medical has developed highly flexible and sensitive brain electrodes. Furthermore, the company has independently crafted a micro-acquisition system and a flexible electrode implantation surgical robot, significantly enhancing surgical precision and safety.
