Abstract

Controlled vibration selectively propels multiple microliter-sized drops along microstructured tracks, leading to simple microfluidic systems that rectify oscillations of the three-phase contact line into asymmetric pinning forces that propel each drop in the direction of higher pinning.

摘要

受控振动可选择性地沿微结构轨道推动多个微升大小的液滴，从而形成简单的微流控系统，该系统将三相接触线的振荡转换为不对称的钉扎力，从而将每个液滴沿较高钉扎力的方向推动。
