N2  - Acoustic metamaterials (AMM) and phononic crystals (PC) have the potential to
unfold a new wave of disruptive technologies to radically transform human
interactions, sensory communications, and beyond. Although essential, cultivating
a deep understanding of the fundamental theory and design principles is insufficient alone, in the practical advancement of AMMs and PCs. Equally important is
the physical realization of these artificial structures for tangible prototyping and
experimental investigation; however, such aspects are seldom discussed in
literature. Herein, the fabrication and assembly approaches for AMMs and PCs are
critically examined, with a tight coupling of theoretical and experimental considerations. Crucial parameters like operating frequency, materials, and geometry for
efficient structural implementation are addressed. Herein, fabrication methods for
specific structure types are categorized under ?single-step fabrication? including
printing and machining and ?multi-step fabrication? like microfabrication and
molding. Various ?assembly? techniques are proposed, such as for ordering
colloidal assemblies or fastening components without adhesives. This framework
uncovers innovative designs, e.g., origami-based structures with conductive
coating, only accessible if fabrication and assembly aspects form an integral part of
the initial design phase. By establishing a greater understanding and awareness of
these methods, a host of undiscovered pathways, opportunities, and research gaps
is revealed, supporting a fresh paradigm for innovation.
