Brain Tiger Technology's second "Three All" brain-machine interface clinical trial successful

On April 23, Brain Tiger Technology announced that after completing the first autonomous, fully implantable, fully wireless, and fully functional (“Three All”) brain-computer interface (BCI) clinical implantation by the end of 2025, the second clinical trial has achieved a key breakthrough. By deeply integrating 50-millisecond end-to-end ultra-low latency with brain-computer interface-driven functional electrical stimulation technology (BCI-FES), it helped a 29-year-old art teacher with a high-level spinal cord injury achieve autonomous eating and painting creation. Interface News learned that the BCI-FES used for the first time in this clinical trial deeply integrates the “Three All” system with functional electrical stimulation (FES) technology to build a complete closed loop of “intention—decoding—stimulation—movement”: by precisely collecting and real-time decoding movement intentions through cortical electrodes, bypassing the damaged spinal cord, and accurately stimulating peripheral muscles, it enables natural, coordinated finger movements. Clinical validation shows that one month after surgery, the patient had already achieved precise active grasping of the affected hand through thought control, and could independently perform high-precision actions such as writing and drawing—truly returning the control targets to the patient’s own limbs.
