The use of additive manufacturing in metallic materials technologically adapted for the production of shape-complex and structurally designed metamaterial components is developed. With a minimum of structural defects and possibly also the spatial integration of piezoelectric or other smart materials and systems into the structure of components will create a technological unit with high application potential. Research on complex hierarchical structures offers significantly improved mechanical properties of a given product with adding additional functionalities (e.g. synergy with sensing for self-sensing components or electrically actuated change of mechanical properties of the structure). Important in this field is the development and research of complex hierarchical structures offering not only significantly improved mechanical and functional properties of the product, but also significant weight savings.
The research of material systems and metamaterial structures with unique electro-mechanical properties enable the integration of a sensing/actuating piezoelectric layer under metamaterial structure. Such a multi-material internally structured metamaterial system is being developed with specific mechanical property requirements in mind, while additional electromechanical functionalities are explored. Metamaterials allow for additional functionality of active electrical signal generation that is proportional to the mechanical load.
