We-LINKING I: World's First Fully Implantable Subdural Cortical Brain-Computer Interface System Launched by WeLinking Medtech in Collaboration with Beijing Tiantan Hospital for Motor Dysfunction Rehabilitation

WE-LINKING Type I Brain-Computer Interface Microsystem: In Vivo and In Vitro Devices and Operating Modes

WE-LINKING Participates in this Clinical Research with the World's First Fully Implantable Subdural Cortical Signal Brain-Computer Interface Microsystem – WE-LINKING Type I, Awarded "Hua Nao Award – Top Ten Advances in China’s Brain-Computer Interface 2024". This system relies on wireless direct power supply and low-power on-chip processing technology, as well as a compliant thin-film neural electrode technology with a thickness of only 1/10 of a hair strand (about 10 micrometers), significantly enhancing safety and clinical acceptance compared to Neuralink's similar products. The CORTEX-0 type thin-film mesh neural electrode array, which can self-adhere and stabilize on the cortical surface, supports over a hundred channels per square centimeter with high-density integration and sub-millimeter spatial resolution, solving the clinical challenge of precisely collecting high-throughput brain signals while avoiding penetrating damage to brain tissue. The implantable part of WE-LINKING Type I consists of 64/128/256-channel CORTEX-0 electrodes and a battery-free electronic package, with a maximum sampling rate of one kilohertz per channel. It is the world’s first clinically graded, fully implantable wireless collector of raw brain signals with hundreds of channels (Neuralink systems collect discrete neural spike data). The implant uses wireless direct power supply design, eliminating the battery for higher electrical safety, enabling high-precision neural signal acquisition, real-time analysis, and wireless transmission.
