Design of a Reconfigurable Microfluidic System Enabled by Magnetic Miniature Robots

Microfluidics permits fluid operations at the microscale. Conventional microfluidic devices have fixed structural configurations, which restrict their adaptability for different applications. A new approach is proposed by integrating magnetic miniature robotic systems into microfluidic platforms, thereby enabling dynamic reconfiguration of the microfluidic chip. As a demonstration, the study presents four types of magnetic miniature robots, i.e., magnetic sorting robot, magnetic variable channel robot, magnetic gyroscope robot, and magnetic rotating flow channel robot, to achieve on‐chip sorting, dynamic regulation of fluid velocity, on‐chip flow regulation, and rapid mixing and bubble manipulation. This work presents a versatile and scalable solution for reconfigurable microfluidic systems, opening new avenues for real‐time control in biological and chemical processes.
