| Modular SAW acoustofluidic tweezer with replaceable assembly units designed for versatile applications; Dachuan Sang (Nanjing University, Nanjing / China) A modular acoustofluidic tweezer that enables modular design, fabrication, and assembly of SAW-driven acoustofluidics will be presented. Independent IDT modules, impedance-matching modules, and a glass-bottom function module are assembled on a common base. Appropriate modules can be selected to meet practical needs, and no wiring is required to interconnect the modules. This tweezer can be easily applied in applications including patterning, manipulation, separation, and concentration, as an effective platform for standardization, cost reduction, and versatility of SAW-driven 1D/2D acoustofluidics. |
| Acoustofluidic Chromatography with polymer devices for fast enrichment of nm-sized particles; Michael Gerlt (Lund University / Sweden) We developed a portable setup for the on-demand trapping and release of nanoscale particles. The system uses a 3D-printed polymer capillary filled with 100 µm SiO₂ beads. A Piezoelectric element is exited at high frequency (5 MHz, thickness mode) for trapping and low frequency (370 kHz, width mode) for release. Trapping efficiency can be characterized in flow using fluorescence imaging and an automated MATLAB script. In the live demo we are using 200 nm fluorescent polystyrene particles. The compact platform includes syringe pumps, the acoustofluidic trapping device, and a DinoLite camera for fluorescence-based analysis. |
| An acoustic washing trap with double-decker capillary-bridge transport connections; Jeremy Hawkes (Acoustic Machines Ltd, Liverpool / UK) Particles trapped in ANY node type are transferred from one medium to another. A Raspberry Pi coordinates the 4 pumps and the sound. Dead volume is almost eliminated by using a thin plastic film to separate the 2 inlet channels and also the 2 outlet channels. Compared to continuous flow systems for particle transfer between fluids. The advantage of this batch system is any nodes can form a trap; a central node is not required. The aim is to work outside the lab in environments where temperature and media are changing. |
| Acoustofluidic On-Demand Chemical Reactor: Precise Liquid Transfer via Tilted Focused Fields using Phased Array and Acoustic Holography; Rujun Zhang, Xinghai Xu, Yuan Yu, Weibao Qiu, Hairong Zheng, Zhiqiang Zhang, Feiyan Cai (Chinese Academy of Sciences, Shenzhen / China) We present an acoustofluidic on-demand chemical reactor that integrates a phased array transducer with a holographic acoustic lens to generate a steerable, tilted focused acoustic field for precise liquid transfer. The holographic lens shapes the acoustic wavefront to achieve accurate spatial focusing, while the phased array enables dynamic beam steering through individual control of transducer elements. By modulating excitation parameters—such as amplitude, pulse width, and phase delay--the system precisely regulates liquid transfer volumes and reaction kinetics. In operation, liquid sample A can be ejected from a microwell A and delivered to reactive sample B, initiating spatially localized chemical reactions. This platform supports contactless, real-time control of reaction rates and minimizes cross-contamination, offering a robust solution for microscale chemical synthesis and analysis. |
| Acoustic Streaming Flow-induced Mass Transfer Through Porous Membrane within Double Layered Microwell Chip; Beomseok Cha, Jinsoo Park (Chonnam National University, Gwangju / Republic of Korea) Here, we investigate acoustic streaming flow (ASF)-induced mass transfer through a porous membrane to achieve rapid and controlled mass transport in membrane-based microfluidics. Surface acoustic wave-based ASF is employed to induce streaming-driven dynamic pressure, which transports the fluid across the membrane boundary. We fabricated a porous membrane-inserted microwell chip where the two fluid layers can be separated. The wave refracts and propagates at a Rayleigh angle (≈ 22°), driving most of the acoustic momentum flow and mass transfer in the vertical direction. The ASF consequently induces dynamic pressure to the porous membrane, driving mass transfer to the top fluid layer. |
| Miniaturized SAW-Based Aerosol Generator for Endoscopic and Technical Applications; Mehrzad Roudini, Steve Wohlrab, Andreas Büst, Andreas Winkler (IFW Dresden, SAWLab Saxony, Dresden / Germany) This demonstration presents a highly compact aerosol generator based on Surface Acoustic Wave (SAW) technology, integrated into the distal end of an endoscope-sized tube (Ø 4 mm). The system enables precise, localized aerosol delivery in minimally invasive medical procedures and confined technical environments. Building on patented SAW technology and novel liquid supply methods, the device offers low power consumption, efficient aerosol generation with minimal heating, and adjustable droplet sizes (100 nm – 30 μm). |
| Icebreakers without blades: Surface acoustic waves for scalable deicing; Kiana Khodakarami, Emma Markward, Andreas Winkler (IFW Dresden, SAWLab Saxony, Dresden / Germany) We demonstrate deicing and ani-icing using surface acoustic waves on lithium niobate. Rayleigh waves propagate over centimeter-scale areas, and remove thick glaze ice through a combination of interfacial mechanical stress, acoustic streaming, and convection. This transparent, low-power system (~0.30 W/cm²) remains effective under freezing conditions, as shown by real-time visualizations of robust deicing and sustained anti-icing. |
| Parallel acoustic bioassembly using droplet arrays; Setthibhak Suthithanakom (Universität Heidelberg, Heidelberg / Germany) This project introduces a droplet of cell-encapsulated hydrogel as a resonator. Trapped between parallel glass slides, the droplet forms a cylinder (Figure a). Its acoustic modes are analytically calculable (Figure b); the first-order mode drives cells/particles to the perimeter (node). Figures c–d show the setup: hydrophobically patterned glass slides held at a fixed gap on a holder platform, allowing multiple droplets to be maintained and assembled in parallel. The platform includes a side-coupled transducer and a Peltier temperature-controlled base. Figure e displays PMMA particles assembled into a ring in a water droplet. |
