843-肌神经致动器与工程生物物理学

from 聊聊Sci

在这项研究中,科学家们开发出一种名为肌神经执行器(MNA)的新型生物混合系统,旨在解决植入式执行器易疲劳的技术难题。研究人员通过再生医学手段,将大鼠的运动神经去除并改用感觉神经重新支配骨骼肌,成功建立了功能性神经肌肉接头,并将肌肉控制权从中枢神经系统移交给计算机控制。由于感觉神经具有更均匀的轴突结构,这种新型执行器的耐疲劳性提升了260%,且能保持组织的自持续性。此外,该系统集成了闭环控制和可逆神经阻断技术,实现了精准调节且不会产生干扰性的神经反馈。这一框架在神经义肢界面和生物混合器官系统(如调节小肠机械运动)中展现了巨大的临床转化潜力,为修复人体功能开辟了新路径。References: Song H, Herrera-Arcos G, Friedman G N, et al.
