XS Vision Achieves Breakthrough with 10,000-Channel Neural Graphics Card System for Visual Brain-Computer Interface

BEIJING — XS Vision, a Beijing-based company spun out of Peking University's technology transfer program, has achieved a series of breakthroughs in its invasive visual brain-computer interface, clearing key hurdles in advanced chip fabrication and human clinical trials, the company announced recently.

The technology, reported by Science and Technology Daily, works by using high-density electrode arrays to directly stimulate the brain's visual cortex. External images are encoded into electrical signals and "written" into the brain, reconstructing artificial vision in patients whose optic nerve pathways have been damaged. The approach is widely regarded as one of the most challenging frontiers in visual rehabilitation — the core difficulty lies not in helping the brain perceive isolated points of light, but in enabling it to truly "see the world."

At the heart of the breakthrough is the company's 10,000-channel neural graphics card system architecture. The 10,000-channel threshold is one of the key benchmarks internationally for measuring high-bandwidth, high-resolution information exchange in the visual brain-computer interface field. With electrode arrays numbering in the tens of thousands, the system is designed to enable large-scale neural signal acquisition and stimulation. Preliminary results from companion human clinical studies have returned positive feedback, according to the company.

The team has also developed and validated a multi-scale neural interface system-level chip, removing physical barriers to full implantation of the visual brain-computer interface and establishing a self-controllable foundation for China's high-end brain-computer interface computing hardware.

Clinical application of brain-computer interface technology must be built on real human brain data. Backed by more than a decade of accumulated data from over 100 cases of invasive electrophysiology and electrical stimulation of the human visual cortex, the team has constructed what it describes as a critical data foundation. The company's closed-loop model — combining massive human data with self-developed high-throughput chips — aims to carve out an independent and controllable technology path for China's brain-computer interface ambitions.
