Abstract
In this work, the efficiency of engineered materials for converting ambient acoustic noise into electrical power is investigated. Of particular interest are 3D-printed acoustic metamaterials. Initial investigation will focus on sonic crystals acoustic metamaterials. Numerical simulations of the acoustic wave and sonic crystals interaction will be conducted. Of particular interests are the strong scattering interactions. 3D-printed samples will be measured and tested. The simulation and measurement results will be presented and discussed.
