NuaiXinJia Achieves Breakthrough with China's First High-Resolution Visual Brain-Computer Interface GCP Clinical Trial

Recently,Caitong SecuritiesCaitong Capital’s wholly-owned subsidiary, Nanochap, has achieved a breakthrough in the field of brain-computer interfaces (BCI). A patient who had been blind for twenty years partially restored functional vision after undergoing China’s first high-resolution visual BCI Good Clinical Practice (GCP) clinical trial in Hangzhou, Zhejiang. This marks a significant milestone for domestically developed BCI projects.

This brain-computer interface (BCI) product was independently developed by a team of Chinese scientists and wholly owned by a domestic Chinese enterprise, achieving full localization of the technology and product supply chain, with China holding complete intellectual property rights. The project has achieved breakthroughs in both the speed and quality of visual reconstruction, establishing a leading position. Beyond mere light perception and contour detection, the high-resolution visual BCI enables patients to recognize letters and images as early as the second day of device activation and calibration. Previously, this level of functionality typically required three to six months of training. Ultimately, aided by the device’s magnification capabilities, the high-resolution visual BCI is expected to help patients restore functional vision, reaching a theoretical visual acuity of 0.5, thereby regaining the ability to recognize faces and perform simple reading tasks, and achieving independence in daily living.

High-Resolution Visual Brain-Computer Interface ProductThe high-resolution visual brain-computer interface product captures images via an external miniature camera, converts optical signals into electrical signals, and performs neural encoding. The device delivers simulated neural signals to the retina through a high-density electrode array, thereby generating visual perception in the cerebral cortex and achieving visual restoration.
