Magnetically powered metachronal waves induce locomotion in self-assemblies
Y. Collard, G. Grosjean, et al.
This groundbreaking research by Ylona Collard, Galien Grosjean, and Nicolas Vandewalle unveils how precessing magnetic fields can trigger metachronal waves in soft ferromagnetic beads at a liquid-air interface, mimicking the movement of legs or cilia. This pioneering method enables precise control of locomotion, even at low Reynolds numbers, using just uniform magnetic fields.
