The technique of acoustic levitation normally produces a standing wave and the potential well of the sound field can be used to trap small objects. Since no solid surface is involved it has been widely applied for the study of fluid physics, nucleation, bio/chemical processes, and various forms of soft matter. In this article, we survey the works on drop dynamics in acoustic levitation, focus on how the dynamic behavior is related to the rheological properties and discuss the possibility to develop a novel rheometer based on this technique. We review the methods and applications of acoustic levitation for the manipulation of both liquid and solid samples and emphasize the important progress made in the study of phase transitions and bio-chemical analysis. We also highlight the possible open areas for future research.
悬浮声学技术通常会产生驻波，声场的势阱可用于捕获微小物体。由于不涉及固体表面，因此它已被广泛应用于流体物理、成核、生物/化学过程和各种形式的软物质的研究。本文综述了悬浮声学中液滴动力学的研究工作，重点讨论了动态行为如何与流变性质相关，并讨论了基于该技术开发新型流变仪的可能性。我们回顾了悬浮声学用于操纵液体和固体样品的方法和应用，并强调了在相变和生物化学分析研究方面取得的重要进展。我们还突出了未来研究的可能的开放领域。
