With the discovery of the liquid spreading mechanism on the peristome of , many studies focusing on uni-directional liquid spreading microstructures have been carried out with an emphasis on structural improvement and the spreading mechanism. Although there are various kinds of microstructures that can accomplish small-scale liquid uni-directional transportation, liquid spreading has not been optimized on a slope because of the unwanted backward flow generated by fabrication defects; inspired by the microstructure of the peristome surface of and the topography of the lizard skin, in this study, we present an innovative, easily processed microstructure that possesses the property of intensified uni-directional liquid spreading even on an oblique substrate. This property is derived from a new, hybrid mechanism that can significantly enhance the uni-directional liquid transportation.
随着对[具体生物名称]口缘液体扩散机制的发现，许多针对单向液体扩散微结构的研究得以开展，重点在于结构改进和扩散机制。尽管存在多种能够实现小规模液体单向传输的微结构，但由于制造缺陷产生的不必要的逆流，液体在斜坡上的扩散尚未得到优化；受[具体生物名称]口缘表面的微结构和蜥蜴皮肤地形的启发，在本研究中，我们提出了一种创新的、易于加工的微结构，该微结构即使在倾斜基板上也具有强化单向液体扩散的特性。这一特性源自一种新的混合机制，该机制能够显著增强单向液体传输。
