Synchron Inc., a brain-computer interface company, is entering clinical trials for its implants in the U.S.
The company plans to place a device called Stentrode, which is smaller than a matchstick, in the brain to help paralyzed patients control digital devices like computer cursors through their thoughts. The implant works by communicating via a tiny wire with a second implant in the chest. A transmitter then sends signals to a computer outside the body, near the patient.
If the study is successful it's estimated that a Synchron device could be on the market in about three to five years.
