本文综述了声微流控技术：利用声场，主要是超声波，在微流控中的应用。虽然声学是一个经典的领域，其有前途的，确实令人困惑的，在强大的操纵流体和粒子在这些流体中的微观尺度到纳米尺度的能力已经恢复了兴趣it.The令人困惑的状态的文献和充足的行话从几十年的研究重组，并提出了从第一原理模型的背景下。这有望使该领域的研究人员在材料科学，流体力学或动力学的经验。被认为是在这些小尺度上很容易出现的非线性相互作用在超声中产生的有趣的现象的丰富，特别是在表面声波器件，是简单的制造与平面光刻技术在微流体，沿着与微流体和纳米流体，通过文献中出现的许多应用。
This article reviews acoustic microfluidics: the use of acoustic fields, principally ultrasonics, for application in microfluidics. Although acoustics is a classical field, its promising, and indeed perplexing, capabilities in powerfully manipulating both fluids and particles within those fluids on the microscale to nanoscale has revived interest in it. The bewildering state of the literature and ample jargon from decades of research is reorganized and presented in the context of models derived from first principles. This hopefully will make the area accessible for researchers with experience in materials science, fluid mechanics, or dynamics. The abundance of interesting phenomena arising from nonlinear interactions in ultrasound that easily appear at these small scales is considered, especially in surface acoustic wave devices that are simple to fabricate with planar lithography techniques common in microfluidics, along with the many applications in microfluidics and nanofluidics that appear through the literature.
