基于声表面波的微液滴驱动

Droplet Driven Based on Surface Acoustic Wave Streaming

在减少昂贵试剂消耗和提高生产能力的需求驱动下,微泵技术得到了广泛的关注和发展。利用声表面波流驱动的微泵在流体雷诺数很小的微尺度下具有一定优势,成为微流控系统中一种重要的补充技术。该文介绍了声表面波在微泵的研究现状,分析了基于表面波的微泵的基本原理,并设计了聚焦型叉指换能器实现微泵功能。对实验器件的设计、选择以及实验过程进行了介绍和分析,并对未来研究工作作出了总结。

The micro-pump system has been greatly developed with the need for less consuming of expensive drug and improving working efficiency.The micro-pump system based on surface acoustic wave streaming has unique advantages at low Reynold′s numbers and becomes an important complement to micro-fluidics system.This paper introduced the research and development of micro-pump,and basic principle of micro-pump based on surface acoustic wave streaming.Function of micro-pump realized by focused interdigital transducers（FIDTs） was designed.Finally the design,selection of the experiment devices was introduced.The experiment process as well as future wok was described and surmised.
