NEO implant. The NEO implant is a wireless brain-computer interface that rests on the dura over the sensorimotor cortex and lets a person with an injury of the cervical spinal cord close and open a hand by intending to grasp, and in March 2026 it became the first implanted brain-computer interface for movement approved for sale anywhere.

Neuracle, a Shanghai company, developed it with Hong Bo's team at Tsinghua University. A titanium unit about 25 mm across replaces a disc of skull, and its eight electrode contacts lie on the dura over the hand areas of the motor cortex and the somatosensory cortex and record epidural electrocorticography without piercing the brain. The unit carries no battery: a coil on the scalp powers it and collects its signals through the skin, and a neural decoder turns the rhythms of attempted grasping into commands for a glove driven by air pressure, which closes the fingers. The first was implanted in Beijing in October 2023, in a man who then learned to drink from a bottle unaided.

It was approved on a small, short trial. China's regulator registered it on 13 March 2026 for adults with injuries at C2 to C6 who keep some arm movement but cannot grasp. The evidence was 36 implants (4 feasibility, 32 confirmatory) followed for 18 months; all participants reached brain-controlled grasping at home, and no serious device-related adverse events were reported.

It trades detail for safety. Eight surface contacts read the summed activity of large populations, enough to tell an intended grasp from rest and far from the many movements that penetrating arrays such as the Utah array can decode.

It is on sale. The first commercial implant was done at Huashan Hospital in Shanghai in July 2026, at a reported cost of 300,000 to 500,000 yuan (about 40,000 to 70,000 dollars) for device, surgery and rehabilitation.

NEO reached the market first by asking little of the brain.

It reads from outside the dura with eight contacts and restores one movement, and that modest reach made the safety case simpler than for the implants that enter the cortex.

Questions: Why can people with NEO's kind of neck injury lift the arm but not grasp? Each segment of the cord sends motor nerves to its own muscles, and an injury cuts the commands to every segment below it. The shoulder and elbow are served mostly from C5 and C6, while the muscles that bend and spread the fingers are wired from C7 to T1, the lowest segments of the neck and the first of the chest. An incomplete injury in the neck can therefore leave a person able to raise the arm and bend the elbow with no working grip, which is the gap NEO fills by reading the intention to grasp from the cortex and handing it to a powered glove. Why was a simple eight-contact implant approved before Neuralink's thousand-electrode one? A regulator weighs the risk of an implant against the benefit a trial has shown, and NEO kept both modest. It sits on the dura without entering the brain, does one job (opening and closing a glove), and reached approval in China on 36 people followed for 18 months. The N1 pushes 64 threads into the cortex to read individual neurons and aims at far richer control, which demands longer evidence that the threads stay put and the tissue tolerates them; in 2026 it is still in early feasibility studies.
