摘要

叉指换能器(IDT)最初被设计为雷达的延迟线。半个世纪后,他们发现了作为微流体系统致动器的新生命。通过产生强声场,它们会触发非线性效应,从而能够泵送和混合流体,并在无接触的情况下移动粒子。然而,从信号处理到致动器的转变带来了一系列关于功率密度和空间分辨率的挑战,这些挑战刺激了固态声学,特别是IDT设计的令人兴奋的发展。假设对声流体学有一定的了解,本文旨在为声流体驱动的IDT设计和表征提供一个教程。它面向不同领域的研究人员,包括流体力学、声学和微电子。

Design of interdigitated transducers for acoustofluidic applications
Interdigitated transducers (IDTs) were originally designed as delay lines for radars. Half a century later, they have found new life as actuators for microfluidic systems. By generating strong acoustic fields, they trigger nonlinear effects that enable pumping and mixing of fluids, and moving particles without contact. However, the transition from signal processing to actuators comes with a range of challenges concerning power density and spatial resolution that have spurred exciting developments in solid-state acoustics and especially in IDT design. Assuming some familiarity with acoustofluidics, this paper aims to provide a tutorial for IDT design and characterization for the purpose of acoustofluidic actuation. It is targeted at a diverse audience of researchers in various fields, including fluid mechanics, acoustics, and microelectronics.
