Description
While acoustic resonators have been extensively studied in liquids for the realization of untethered microrobots, their implementation in air remains largely unexplored. Here, we revisit the classical principle of Helmholtz resonance and show that 3D printed cavities with sizes ranging from centimeter to micrometer generate spatiotemporally controlled thrust ranging from millinewton to micronewton upon resonance excitation.
