China has approved the world’s first invasive brain-computer chip—here’s what’s next

One day last October, sitting in the courtyard of his house in China’s Henan province, Dong Hui decided to   see if he could hold a pen to write.  Dong, 39, had sustained spinal cord injuries in a car accident six years earlier that left him paralyzed from the neck down. Slowly but determinedly, he wrote his name, “Thank you,” and then the date. This was the result of an 11-month-long rehabilitation enabled by an implant in his brain. Before that process, Dong could move his arms slightly but wasn’t able to use his fingers.

In November 2024, Dong became one of the first people in China to be given an invasive brain-computer interface (BCI) through brain surgery. He had signed up for a clinical trial with the device’s developer one month after seeing on TV how a BCI had apparently enabled another paralyzed Chinese man to hold his granddaughter.  This March, the implant Dong uses became the first invasive BCI product in the world to be approved for use beyond clinical trials. It’s now available to some patients with paralysis in their limbs due to spinal cord injuries.

Dong’s brain implant is a coin-size device called NEO. It was developed by Neuracle Technology, a Shanghai-based startup, together with researchers at Tsinghua University in Beijing.  During a procedure that took just over an hour and a half, the device’s sensors, which collect Dong’s brain signals, were placed on his dura mater, the tough outer layer of tissue that covers and protects the brain. The signals are transmitted to a computer by an implant placed on Dong’s skull. The computer then translates the signals into commands for a soft robotic glove Dong wears during the 2.5-hour training sessions he completes each day to help him learn to grab. 

Dong started his rehabilitation around a week after surgery. “On the ninth day of my training, my right hand successfully grabbed a ball without the glove,” he says. “That was a miraculous moment.”   Now he continues with his training at home. He wants to be able to control his hands better in order to put on clothes, eat, and do other daily tasks without troubling his aging parents. 

A growing number of people with traumatic injuries in China are now poised to tread a similar path thanks to NEO’s recent approval. According to China’s National Medical Products Administration, the bureau responsible for drug supervision, the product is suitable for patients between 18 and 60 who have paralysis in all limbs due to spinal cord injuries but still have some residual function in their arms. 

NEO beat several other BCIs to approval, including one from Neuralink, a California-based company founded by Elon Musk.

Days after NEO was approved, China started incorporating it into the country’s health insurance system by assigning it a unique code. This is one of the first steps toward a future where eligible Chinese patients pay a certain percentage of the BCI’s price if they need it during their treatment.

The growth of China’s BCI industry is expected to accelerate thanks to the government’s policy support and financial backing. The country’s latest five-year plan, published on the same day Neuracle received its approval, lists BCI as one of six key industries important to China’s future tech competitiveness, alongside quantum technology, humanoid robots, and others. Several Chinese startups, including NeuroXess and StairMed, have already worked in the field for many years.

NEO has become the world’s first invasive BCI to go commercial, but scientists interviewed by MIT Technology Review caution against comparing Chinese and US efforts through the lens of a race.
