Locomotion of magnetoelastic membranes in viscous fluids

The development of multifunctional and biocompatible microrobots for biomedical applications relies on achieving controllable locomotion. Here we describe the conditions that allow homogeneous magnetoelastic membranes composed superparamagnetic particles to swim through viscous fluids. By solving equations motion, find dynamical modes circular in precessing magnetic fields, which are found actuate or out synchronization with a field above below critical precession frequency ${\ensuremath{\omega}}_{c}$, respectively. For frequencies larger than synchronized transverse waves propagate membrane along rotational (perimeter) radial directions. Using lattice Boltzmann approach, show how these give rise locomotion an incompressible fluid at low Reynolds numbers. Nonreciprocal motion resulting swimming is achieved by breaking morphological symmetry membrane, attained via truncation segment. translation can be adapted predetermined path programming external field. Our results lay foundation directed thin, diverse array geometries.
