Abstract Scope Recently, there has been considerable interests of hydrophones for the purpose of underwater signal detection. However, conventional hydrophones suffer from the narrow working frequency and limited directivity patterns. Herein, we designed and fabricated novel hydrophones consisting of micro-architected metamaterials to accommodate diverse situations, in which the piezoelectric composites convert mechanical vibrations into electrical voltages. 3D printable piezoelectric composites were used to fabricate these architected hydrophones that have high sensitivity. Through tuning geometry of the micro-architectures, resonance frequencies of these hydrophones can vary from 100Hz to 10MHz, which is across 5 orders of magnitude. With this broad frequency range, we combined multiple architecture designs and fabricated hydrophones with arbitrary directivity patterns. Compared to conventional hydrophone arrays, the metamaterial hydrophones have no limitation on the shape of the directivity patterns. In addition, we showed the applicability of these hydrophones for the purpose of source detection, liquid quality monitoring, and directional sensing.
