Design of a Reconfigurable Microfluidic System Enabled by Magnetic Miniature Robots

Advanced Intelligent Systems, EarlyView.
Magnetic miniature robots are integrated into microfluidic chips to achieve real‐time reconfiguration. By external magnetic actuation, the robots perform sorting, mixing, flow regulation, and bubble removal on demand. This versatile platform eliminates the need for complex on‐chip hardware and enables adaptive control for biological and chemical ...

A Compact, Self‐Recovering Wire Electrode Electrohydrodynamic Pump for High‐Speed McKibben Artificial Muscle Actuation

Advanced Intelligent Systems, EarlyView.
A compact and self‐recovering wire electrode electrohydrodynamic pump achieves high pressure, fast flowrate, and automatic recovery after dielectric discharge breakdowns. The pump delivers twice the power density of previous designs, and when integrated with a McKibben artificial muscle, enables tenfold faster actuation, offering a lightweight, silent,
