On May 18, 2026, China marked a significant milestone by officially launching its first multi-center clinical trial for a 128-channel, fully implantable brain-computer interface system. This groundbreaking endeavor is being spearheaded by Beijing Tiantan Hospital, which is affiliated with Capital Medical University. The system comprises intracortical implantable flexible electrodes and a highly integrated, fully implantable signal acquisition device.

The flexible electrodes, crafted from ultra-thin, biocompatible materials, are designed to minimize immune responses. They are capable of accurately capturing single-neuron action potentials, thereby enhancing both information decoding capabilities and transmission rates. Meanwhile, the fully implantable signal acquisition device supports wireless charging, facilitating the simultaneous collection and transmission of high-channel neural signals. This innovative design ensures clinical convenience and safety, meeting the stringent requirements of modern medical practice.
