London (CNN Business) Elon Musk wants to insert Bluetooth-enabled implants into your brain, claiming the devices could enable telepathy and repair motor function in people with injuries.

The chip features a USB-C port, the same adapter used by Macbooks , and connects via Bluebooth 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 said, playing up the device's diminutive size.

Neuralink, a startup founded by Musk , says the devices can be used by those seeking a memory boost or by stroke victims, cancer patients, quadriplegics or others with congenital defects.

The company says up to 10 units can be placed in a patient's brain. The chips will connect to an iPhone app that the user can control.

The devices will be installed by a robot built by the startup. Musk said the robot, when operated by a surgeon, will drill 2 millimeter holes in a person's skull. The chip part of the device will plug the hole in the patient's skull.

"The interface to the chip is wireless, so you have no wires poking out of your head. That's very important," Musk added.

Trials could start before the end of 2020, Musk said, likening the procedure to Lasik eye correction surgery, which requires local anesthetic.

Elon Musk is the founder of Neuralink, which is building chips that will be implanted in people's brains.

Musk has said this latest project is an attempt to use artificial intelligence (AI) to have a positive effect on humanity. He has previously tried to draw attention to AI's potential to harm humans.

He has invested some $100 million in San Francisco-based Neuralink, according to the New York Times.

Google GOOGL Facebook FB Musk's plan to develop human computer implants comes on the heels of similar efforts byand. But critics aren't so sure customers should trust tech companies with data ported directly from the brain.

"The idea of entrusting big enterprise with our brain data should create a certain level discomfort for society," said Daniel Newman, principal analyst at Futurum Research and co-author of the book Human/Machine.

"There is no evidence that we should trust or be comfortable with moving in this direction," he added.

While the technology could help those with some type of brain injury or trauma, "Gathering data from raw brain activity could put people in great risk, and could be used to influence, manipulate and exploit them," Frederike Kaltheuner of Privacy International told CNN Business. "Who has access to this data? Is this data shared with third parties? People need to be in full control over their data."

The tech industry is coming under heightened scrutiny over how it handles data.

France fined Google parent company Alphabet in January for violating EU online privacy rules. Facebook reportedly faces a major fine in the United States over its own data privacy violations.
