Core Insights - The research teams from the Shenzhen Institute of Advanced Technology and Donghua University have developed a new type of neural fiber electrode called "neural worm," which is ultra-thin, flexible, and capable of dynamic movement, marking a significant advancement in brain-machine interface technology [1][2] - This innovation introduces a new paradigm of "dynamic electrodes" for brain-machine interfaces, moving away from the traditional static electrodes that limit application and development [1] Group 1: Research and Development - The neural fiber electrode has a diameter of only 196 micrometers and can accommodate 60 independent signal channels, achieved through meticulous steps in flexible film preparation and conductive pattern design [1] - The research took five years to develop, culminating in a publication in the journal Nature [1] Group 2: Performance and Longevity - The neural fiber electrode has successfully operated in the leg muscles of rats for over 43 weeks using minimally invasive implantation techniques [2] - After 13 months, the average thickness of the fibrous encapsulation layer surrounding the electrode was less than 23 micrometers, comparable to normal tissue, while traditional stainless steel wire electrodes showed encapsulation thickness exceeding 451 micrometers and significant cell apoptosis [2] Group 3: Functionality and Control - The neural fiber electrode can autonomously adjust its position within the brain of rabbits using a high-precision magnetic control system and real-time imaging tracking, allowing for stable recording of high-quality biological signals [1] - Under external magnetic field control, the electrode can move on the muscle surface and change its position daily within the first week post-implantation to monitor electrode signals [2]
