One of the major challenges in modern robotics is controlling micromanipulation by active and adaptive materials. In the respiratory system, such actuation enables pathogen clearance by means of motile cilia. While various types of artificial cilia have been engineered recently, they often involve complex manufacturing protocols and focus on transporting liquids only. Here, soft magnetic carpets are created via an easy self-assembly route based on the Rosensweig instability. These carpets can transport not only liquids but also solid objects that are larger and heavier than the artificial cilia, using a crowd-surfing effect.This amphibious transportation is locally and reconfigurably tunable by simple micromagnets or advanced programmable magnetic fields with a high degree of spatial resolution. Two surprising cargo reversal effects are identified and modeled due to collective ciliary motion and nontrivial elastohydrodynamics. While the active carpets are generally applicable to integrated control systems for transport, mixing, and sorting, these effects can also be exploited for microfluidic viscosimetry and elastometry.

通过软磁地毯进行液体和固体的两栖运输
现代机器人技术的主要挑战之一是通过活性和自适应材料控制微操作。在呼吸系统中，这种驱动使得能够通过活动纤毛清除病原体。虽然最近设计了各种类型的人造纤毛，但它们通常涉及复杂的制造方案并且仅专注于运输液体。在这里，软磁地毯是通过基于 Rosensweig 不稳定性的简单自组装路线创建的。这些地毯不仅可以利用人群冲浪效应运输液体，还可以运输比人造纤毛更大、更重的固体物体。这种两栖运输可以通过简单的微磁铁或具有高度空间性的先进可编程磁场进行本地和可重新配置的调节。解决。由于集体纤毛运动和重要的弹性流体动力学，两个令人惊讶的货物逆转效应被识别和建模。虽然活性地毯通常适用于运输、混合和分类的集成控制系统，但这些效应也可用于微流体粘度测定和弹性测定。
