China's first clinical trial of a brain-computer interface (BCI) has successfully enabled a tetraplegic patient to control devices using only brain signals. Conducted in March by researchers from the Shanghai-based Center for Excellence in Brain Science and Intelligence Technology, the implant boasts a diameter of just 26 millimeters and is over 100 times more flexible than Neuralink's device. Plans are underway to enable the patient to control a robotic arm by 2028, marking a significant advancement in BCI technology.
