Abstract

Microfluidics are crucial for managing small-volume analytical solutions for various applications, such as disease diagnostics, drug efficacy testing, chemical analysis, and water quality monitoring. The precise control of flow control devices can generate diverse flow patterns using pneumatic control with solenoid valves and a microcontroller. This system enables the active modulation of the pneumatic pressure through Arduino programming of the solenoid valves connected to the pressure source. Additionally, the incorporation of solenoid valve sets allows for multichannel control, enabling simultaneous creation and manipulation of various microflows at a low cost. The proposed microfluidic flow controller facilitates accurate flow regulation, especially through periodic flow modulation beneficial for droplet generation and continuous production of microdroplets of different sizes. Overall, we expect the proposed microfluidic flow controller to drive innovative advancements in technology and medicine owing to its engineering precision and versatility.

利用基于 Arduino 的气动控制微流控装置实现微尺度流量控制和液滴生成
微流控技术对于管理疾病诊断、药效测试、化学分析和水质监测等各种应用中的小容量分析解决方案至关重要。利用电磁阀和微控制器进行气动控制,对流量控制装置进行精确控制,可以产生多种流动模式。通过对连接到压力源的电磁阀进行 Arduino 编程,该系统能够主动调节气动压力。此外,电磁阀组的加入可实现多通道控制,从而以较低的成本同时创建和操纵各种微流。拟议的微流体流量控制器有利于精确调节流量,特别是通过周期性流量调节,有利于液滴的生成和不同大小微滴的连续生产。总之,由于其工程精度和多功能性,我们期待所提出的微流体流量控制器能够推动技术和医学的创新发展。
