Abstract

This paper demonstrates ultrasound-activated synthetic ciliary bands mimicking starfish larva's ciliary band arrangements. Nonlinear acoustics at microscales drives bulk fluid motion through acoustically actuated cilia oscillations. Angled ciliary bands create flow sources (+) or sinks (−), enabling acoustic propulsion by circumventing the scallop theorem. A microparticle trap is demonstrated by arranging + and − bands, analogous to a starfish larva's feeding mechanism.
