Abstract Pentamode materials are special solid materials mimicking complex flfluid, which could achieve desired mechanical properties through microstructure design of conventional solids. Tunable mechanical properties and solid merit endow pentamode materials with prospective application in broadband underwater acoustic wave manipulation such as acoustic cloaking and focusing, which stimulates an intense research activity recently. In this review, basic concept of pentamode materials and the status of microstructure design were introduced firstly, then the corresponding devices fabrication and experimental verifification based on conventional manufacturing techniques and additive manufacturing are illustrated elaboratively, and the technical demanding and trending is proposed fifinally.
