Abstract: 
Polymer-based materials with patterned functional particles have been used to develop smart devices with multiple functionalities. This paper presents a novel method to pattern microscale particles into biocompatible polyethylene glycol diacrylate (PEGDA) fluid through a designed surface acoustic wave (SAW) device with slanted-finger interdigital transducers (SFITs). By applying signals of different frequencies, the SFITs can excite SAWs with various wavelengths to pattern the microscale particles. The structural design and working principle of the SAW device with SFITs are firstly presented. To investigate the generation of standing SAWs and pressure field distributions of the SAW device with SFITs, a numerical model was developed. Simulation results showed that different strip-shape patterned pressure fields can be generated, and the period and width of adjacent strips can be adjusted by changing the frequencies of the excitation signals. Experiments were performed to verify that the microscale particles in the PEGDA solution can be successfully patterned into strip-shape patterns with various positions, periods, and widths. The results obtained in this study demonstrate that the developed method of using an SAW device with SFITs can be used for tunable patterning of microscale particles in solutions, and shows great potential for biomedical and microfluidic applications.

基于斜指换能器声表面波器件的微颗粒可调排布研究

目的:可调粒子排布是含规则排布功能介质的聚合物材料制造中的一大难题.本文旨在设计一种带斜指换能器的声表面波器件,并开展微颗粒可调排布的仿真及实验研究.
创新点:1. 提出了一种新的微颗粒排布方法,通过所设计的带斜指换能器的声表面波器件,在聚乙二醇二丙烯酸酯(PEGDA)中实现对微颗粒的可调排布.2. 建立了微颗粒排布过程的有限元仿真模型,研究了声表面波的产生、传递和PEGDA中声压场的分布,以及分析了微颗粒的可调排布原理.3. 通过施加不同频率的激励信号,可实现同一液层中不同位置、不同间隙规律的粒子排布.
方法:1. 为了在PEGDA中实现对微粒子的可调排布,设计一种带斜指换能器的声表面波器件,并采用该装置实现不同周期、宽度、位置的微颗粒排布;2. 建立声-结构耦合的时域仿真模型对斜指换能器的声表面波器件中声表面波的产生、传递及PEGDA中声压场的分布进行研究;3. 通过实验研究,验证不同频率激励信号对粒子排布周期、宽度和位置的影响,证明该方法的有效性和灵活性.
结论:1. 所提出的基于带斜指换能器声表面波器件的微颗粒排布方法,实现了PEGDA中排布周期从83.9 μm到116.4 μm变化、宽度从710 μm到1145 μm变化的可调粒子排布;2. 微颗粒排布周期和宽度随所施加激励信号频率的增加而减小,且排布周期约等于该频率激励信号所激发声表面波波长的一半;3. 通过相继施加不同频率的激励信号,可以在液层不同区域形成不同的粒子排布并同时保留,互不干扰.
