2191-530X with piezoelectric materials in the study and design of piezo-augmented arrays of resonators. The energy harvesting performances of the graded metamaterials are then compared to conventional solutions, in order to quantify their advantages for applications.978-3-030-69059-5978-3-030-69060-1Series ISSN 2191-530X Series E-ISSN 2191-5318

Self-Assembly of Biological Macromolecules,e. a spatial signal separation depending on frequency. Finally, reversed mode conversion from surface Rayleigh to Shear (S) and Pressure (P) bulk waves is demonstrated leveraging on the Umklapp phenomenon. This mechanism allows to manipulate surface waves, focusing the elastic energy in specific regions for a broadband input frequency.

Advanced Multiresonator Designs for Energy Harvesting,This chapter, starting from basic concepts on piezoelectric materials, explores piezo-augmented arrays of resonators able to dramatically increase the energy available for harvesting, and the operational bandwidth. Specifically, three designs are proposed, exploiting rainbow reflection, trapping, and topological edge modes.
