Abstract: Acoustic Metamaterials In article number 2404093, Christabel Choi, Sriram Subramanian, and co-workers achieve continuous out-of-plane actuation >5 mm of objects using fluid-driven membrane-based actuation. Fluidic chip prototypes consisting of multi-layered channels are fully 3D-printed, with an elastomeric membrane attached to the surface, which is interfaced with acoustic metamaterial reflectors. Controlled inflation and deflation of sections of the membrane enables actuation of an acoustic metasurface, designed for acoustic focusing at five different locations.
