A groundbreaking semi-invasive brain-machine interface (BMI) system developed in China has enabled an aphasic patient to communicate in Chinese for the first time, marking a leap in neurotechnology applications. Researchers from the Chinese Institute for Brain Research (CIBR), Xuanwu Hospital, and NeuCyber NeuroTech revealed that their wireless BMI system uses flexible nano-electrodes and advanced algorithms to decode brain signals tied to speech and motion.
The NeuCyber Matrix BMI System, implanted via minimally invasive surgery, recorded a 98% functional success rate in clinical trials. A patient with amyotrophic lateral sclerosis (ALS) regained basic communication abilities within weeks, with single-character decoding now taking under 100 milliseconds. "The system translates thoughts into text or device commands, empowering those with severe motor impairments," said NeuCyber's Li Yuan.
Key innovations include a high-precision microelectrode film positioned on the brain's surface, wireless near-field communication, and AI-powered error correction. Paralysis patients using the BMI have also successfully controlled robotic arms and computers, according to CIBR Director Luo Minmin.
Xuanwu Hospital's team aims to expand the technology for epilepsy, spinal injuries, and stroke rehabilitation. "This opens new doors for neurological care," said hospital President Zhao Guoguang, noting ongoing improvements in decoding accuracy.
