China has approved a brain implant that enables people with paralysis to move their hands. The regulatory nod, granted to Neuracle (Borui Kang Medical Technology) in Shanghai, is the world’s first approval of an invasive brain–computer interface for commercial use.

The electrodes record neuronal electrical activity when a person imagines moving their hand. The signals are sent to a computer, decoded, and then used to control a robotic glove worn by the patient, moving their hand.
