Summary: A multi-level magnetic delivery strategy is proposed for robust and highly efficient transportation of microrobots within a hierarchical vascularized organ-on-a-chip system. The strategy combines a tethered microrobotic guidewire and untethered swimming microrobots to overcome the challenges faced by existing delivery strategies. A hierarchical vascular network is also constructed, providing an in vivo-like testing platform. Experimental results demonstrate the effectiveness of the strategy in delivering microrobots and reducing the risk of intravascular thrombosis.

Summary: This study examines the effect of inertia on the time-averaged propulsive performance of a thin, flexible, two-dimensional and non-uniform foil undergoing prescribed pitching and heaving motion. For a rigid foil, inertia does not affect the cycle-averaged propulsive performance in harmonically oscillating motion, regardless of the amplitude. However, for a flexurally deflected foil, the cycle-averaged inertial thrust and lift vanish while the cycle-averaged power input remains. The results provide analytical insights into the conditions that minimize power consumption.
