A model for actuating a synthetic microswimmer with a flexible flagella using an acoustic field to excite an oscillating wave in the flagellum is presented in this paper. In order to create the largest possible wave amplitudes, the wavenumber of the fluid is matched to the wavenumber of the microswimmer's flagellum at a particular modal frequency. An analytic model of this approach shows that a ... read morestiff material, such as nickel, is most appropriate for this coupling. However, 3D numeric simulation suggests that amplitudes of the wave produced by this coupling are on the order of subangstrom and are too small to create cell-like swimming. Further study is needed to understand the system of a microswimmer in fluid, and associated 2nd-order effects, to drive larger oscillatory amplitudes.read less
