仿生振动诱导液滴脱钉实现表面微凸体内埋藏颗粒的提取
Bioinspired Vibration‐Induced Droplet Depinning Enables Extraction of Particulates Buried Within Surface Asperities
AI 导读
受鸟类防水羽毛与补偿性振翅协同策略启发，研究构建了振动驱动的液滴脱钉表面清洁平台，采用类羽毛疏水膜促进液滴与污染物相互作用并通过振动释放液滴。基于将液滴视为弹性体的流体动力学模型建立了能量框架，可量化不同表面润湿性下振动与重力对界面粘附的影响并给出分离判据。该表面技术可高效去除嵌入表面微凸体内的细颗粒，有望用于光学传感器与移动平台。
