“…As the distance between the magnet array and MRMAs altered from 0 mm to 5 mm, the bending angle changed drastically, from 0 • to 64 • . This drastic change in bending angle comes from the characteristics of the magnetic field distribution of a Halbach array, which shows a dramatic reduction of magnetic field intensity as the distance from the magnet array increases [32][33][34]. In this experiment, as depicted in figure 2(c) when the distance reached 2.5 mm and below, bending of the MRMA was maximized as making full contact with the neighboring walls.…”

This research provides a comprehensive exploration of the development and characterization of magnetically responsive microwall arrays (MRMAs), presenting a novel approach to precise droplet manipulation. The proposed fabrication process involves microscale wall arrays created using carbonyl iron particles (CIPs) embedded in polydimethylsiloxane (PDMS) through a replica molding process. The MRMAs demonstrate a unique response to magnetic fields, enabling precise control over droplet movement. Through superhydrophobic coatings, the system facilitates the efficient movement of droplets along predefined routes, achieving outstanding accuracy in droplet directionality and positioning with only a single direction of magnetic field control. The experiments highlight the capability of MRMAs to merge differently colored droplets, underscoring their potential in long-distance droplet transportation. The results suggest applications in microfluidic systems, lab-on-a-chip devices, and targeted drug delivery, marking a significant advancement in microfluidic research.
