Elon Musk is working with scientists to develop a Bluetooth-enabled implant to repair motor function in people with injuries.

Neuralink Corp, a startup founded by Musk, unveiled the plans at an event on Tuesday in San Francisco.

In the works for the last two years, the device will consist of a tiny chip connected to 1,000 wires “measuring the one-tenth the width of human hair.”

It would feature a USB-C port, connecting via Bluetooth to a small computer worn over the ear and to a smartphone, Musk said.

“If you’re going to stick something in a brain, you want it not to be large,” Musk was quoted as saying by CNN.

Installed by a surgeon-operated robot into a patient’s skull, the device could help stroke victims, cancer patients, quadriplegics or others with congenital defects.

Trials could start before the end of 2020, the CEO of Tesla and SpaceX said.
