Brain-machine interfaces (BMIs) that can precisely monitor and control neural activity will likely require new hardware with improved resolution and specificity. New nanofabricated electrodes with feature sizes and densities comparable to neural circuits may lead to such improvements. In this perspective, we review the recent development of vertical nanowire (NW) electrodes that could provide highly parallel single-cell recording and stimulation for future BMIs. We compare the advantages of these devices and discuss some of the technical challenges that must be overcome for this technology to become a platform for next-generation closed-loop BMIs.
脑机接口（BMI）需要新的硬件来提高分辨率和特异性，以便更精确地监测和控制神经活动。具有类似神经回路的特征尺寸和密度的新型纳米制造电极可能会带来这些改进。在这篇观点文章中，我们回顾了垂直纳米线（NW）电极的最新发展，这些电极可为未来的 BMI 提供高度并行的单细胞记录和刺激。我们比较了这些设备的优势，并讨论了为使这项技术成为下一代闭环 BMI 的平台必须克服的一些技术挑战。
