Abstract

Rotational acoustic manipulation technology offers precise control of particle motion, making it advantageous for applications in microfluidics, biomedicine, materials research, and so on. Current advanced techniques that use acoustic waves to rotate particles include microstructure vibration, microbubble oscillation, and acoustic holography. Although these methods have achieved some success in rotational acoustic manipulation, they face challenges such as limited types of particles, complex device fabrication, and single-mode manipulation. To address these issues, this study proposes a novel rotational acoustic manipulation device based on traveling wave acoustic fields. The traveling wave acoustic field is achieved by planning the vibration modes of the vibrational source. In this study, a ring-shaped piezoelectric ceramic with four-quadrant dual polarization is designed to excite two orthogonal B₁₁ bending vibration modes of the vibrator. By adjusting the phase difference of the excitation signals, these two B₁₁ bending vibration modes can be coupled into either clockwise or counterclockwise traveling wave vibration modes, thereby establishing unidirectional rotating traveling waves in the water within the PDMS ring. The PDMS ring features an open structure, meeting the requirements for manipulating both floating and submerged particles. The performance of the proposed acoustic manipulation device is validated and analyzed through experiments with hollow glass particles, hollow polystyrene particles, and solid polystyrene particles. The results demonstrate that the proposed acoustic manipulation device can achieve precise fixed-point self-rotation and regional revolution manipulation of particles, regardless of their floating, submerged, hydrophilic, or hydrophobic properties. This indicates the high universality and robustness of the device, making it applicable for the manipulation of various types of particles. Overall, this study introduces a novel acoustic manipulation method for particle rotation, providing strong support for the development and application of acoustic manipulation devices in diverse fields.

用于亲水/疏水漂浮和浸没颗粒的多模式旋转声学操纵装置

旋转声波操纵技术可精确控制粒子运动，因此在微流体、生物医学、材料研究等领域的应用中具有优势。目前利用声波旋转粒子的先进技术包括微结构振动、微气泡振荡和声全息技术。虽然这些方法在旋转声波操纵方面取得了一定的成功，但它们面临着粒子类型有限、设备制造复杂和操纵方式单一等挑战。为了解决这些问题，本研究提出了一种基于行波声场的新型旋转声学操纵装置。行波声场是通过规划振动源的振动模式来实现的。本研究设计了一个具有四象限双极化的环形压电陶瓷，用于激发振动器的两个正交 B11 弯曲振动模式。通过调整激励信号的相位差，这两个 B11 弯曲振动模式可以耦合成顺时针或逆时针的行波振动模式，从而在 PDMS 环内的水中形成单向旋转行波。PDMS 环具有开放式结构，可同时满足操纵漂浮和浸没颗粒的要求。通过对空心玻璃颗粒、空心聚苯乙烯颗粒和实心聚苯乙烯颗粒进行实验，验证和分析了所提出的声学操纵装置的性能。结果表明，所提出的声学操纵装置可以实现颗粒的精确定点自旋转和区域旋转操纵，而不受颗粒的漂浮、浸没、亲水或疏水特性的影响。这表明该装置具有很强的通用性和鲁棒性，可用于操纵各种类型的粒子。总之，本研究介绍了一种新颖的颗粒旋转声学操纵方法，为声学操纵装置在不同领域的开发和应用提供了有力支持。
