In response to clinical needs such as repairing movement and language disorders caused by brain damage, BrainTiger Technology has independently developed a 256-channel high-throughput implantable flexible brain-computer interface. Recently, it has carried out clinical trials of high-precision real-time movement decoding and language decoding at Huashan Hospital affiliated to Fudan University. Two days after the operation, patients can carry out movement/language decoding tests, and within two weeks, they can realize "brain control" of smart devices and "mind dialogue". Patients recover well after the operation. This is the world's first clinical trial of language and movement "dual decoding" brain-computer interface.
