Abstract

We demonstrate a new type of gaseous fuel for rolled-up tubular Ti/Cr microengine powered by carbon dioxide microbubbles in carbonated water and brewed beverages. Existence of microbubble pockets is revealed using on-chip integrated transparent microtubes. Vertical position, angle of rotation and buoyancy of ferromagnetic Ti/Fe/Cr microengines are controlled using an external magnetic field.

摘要

我们展示了一种新型气态燃料，用于在碳酸水中和酿造饮料中由二氧化碳微泡驱动的卷绕管状 Ti/Cr 微引擎。使用片上集成的透明微管揭示了微泡袋的存在。使用外部磁场控制铁磁 Ti/Fe/Cr 微引擎的垂直位置、旋转角度和浮力。
