Acoustofluidic devices have continuously demonstrated their potential to impact medical diagnostics and lab-on-a-chip applications. To bring these technologies to real-world applications, they must be made more accessible to end users. Herein, we report on the effort to provide an easy-to-use and portable system for controlling sharp-edge-based acoustofluidic devices. With the use of a cell phone and a modified Bluetooth® speaker, on-demand and hands-free pumping and mixing are achieved. Additionally, a novel design for a sharp-edge-based acoustofluidic device is proposed that combines both pumping and mixing functions into a single device, thus removing the need for external equipment typically needed to accomplish these two tasks. These applications serve to demonstrate the potential function that acoustofluidic devices can provide in point-of-care platforms. To further this point-of-care goal, we also design a portable microscope that combines with the cell phone and Bluetooth® power supply, providing a completely transportable acoustofluidic testing station. This work serves to bolster the promising position that acoustofluidic devices have within the rapidly changing research and diagnostics fields.

由手机控制的声流体装置†

声流控设备不断证明其影响医疗诊断和芯片实验室应用的潜力。为了将这些技术应用于现实世界，必须让最终用户更容易使用它们。在此，我们报告了为控制基于锐边的声流体设备提供易于使用和便携式系统的努力。通过使用手机和改进的蓝牙®扬声器，可以实现按需和免提的泵送和混音。此外，还提出了一种基于锐边的声流装置的新颖设计，它将泵送和混合功能结合到单个装置中，从而消除了完成这两项任务通常所需的外部设备的需要。这些应用展示了声流控设备在护理点平台中可以提供的潜在功能。为了进一步实现这一护理点目标，我们还设计了一款便携式显微镜，它与手机和蓝牙®电源相结合，提供了一个完全可移动的声流测试站。这项工作有助于巩固声流控设备在快速变化的研究和诊断领域中的前景。
