超声驻波可用于在流体内的颗粒上产生力。这种力在微流体装置中具有许多潜在的应用。本文描述了一种在微流体规模上提供过滤的装置。它是微型制造的，并使用兆赫频率范围内的超声波将颗粒集中在流内的节点处。它为微流体系统提供了功能等同于离心分离器的可能性。它使用硅和Pyrex制造，因此与现有的微加工技术兼容。讨论了该装置的建模、设计、制造和控制。(C)2003 Elsevier B.V保留所有权利。
Ultrasonic standing waves can be used to generate forces on particles within a fluid. Such forces have a number of potential applications in microfluidic devices. This paper describes a device that provides filtration on a microfluidic scale. It is microfabricated and uses ultrasound in the megahertz frequency range to concentrate particles at a node within the flow. It offers the possibility of a functional equivalent of a centrifugal separator for microfluidic systems. It is constructed using silicon and Pyrex, and hence is compatible with established microfabrication techniques. The modelling, design, fabrication and control of the device are discussed.
