A groundbreaking advancement in brain-machine interface technology is changing lives in the Chinese mainland. A research team from the Chinese Institute for Brain Research (CIBR), in collaboration with Capital Medical University-affiliated Xuanwu Hospital and NeuCyber NeuroTech (Beijing) Co., Ltd., has successfully performed multiple full cortical BMI implantations. This innovative NeuCyber Matrix BMI System has enabled an aphasic patient to output Chinese and empowered paralyzed patients to control computers and robotic arms.
The semi-invasive approach involves implanting a thin, flexible nano-fabricated film microelectrode on the dura mater, capturing high-quality neural signals with minimal surgical trauma. A coin-sized control and signal transmission device, embedded on the patient’s skull, facilitates efficient wireless power supply and near-field communication. Clinical reports indicate that over 98% of the BMI channels remain functional after surgery, underscoring the system’s robustness.
At the press conference, experts detailed three key innovations powering the system: a high-integration micro-host for processing high-flux, low-power signals; a state-of-the-art wireless short-range communication technology for low-power, high-bandwidth data transmission; and a real-time, multi-scenario algorithm capable of decoding fine motor movements and Chinese language with impressive speed—now achieving decoding latencies below 100 milliseconds per character.
The breakthrough was further highlighted when the aphasic patient began language decoding training on March 14, rapidly improving accuracy from 34% to 52% for 62 common Chinese words. With the aid of an adaptive error correction algorithm based on a large language model, the system has already enabled the patient to communicate simple sentences like "I want to drink water," "I want to eat," and "I'm in a great mood today. I'd like to take a walk with my family."
Researchers believe that this semi-invasive BMI technology opens a new chapter in rehabilitative medicine, offering long-term and stable solutions for patients facing challenges such as aphasia, amyotrophic lateral sclerosis (ALS), stroke, and other neurological conditions. Future clinical practices will explore its potential in treating intractable epilepsy, spinal cord injuries, and more, promising a brighter outlook for patients and transforming the landscape of medical technology.
