State of the art on the recovery of mechanical energy in the city. The role of seismic metamaterials
Studies on structured soils, including seismic metamaterials, have shown the existence of complex wave phenomena within and around the structured zone. The aim is to assess areas where seismic or vibratory energy is concentrated, and to decide whether it would be worthwhile to exploit them by judiciously placing piezoelectric energy sensors. The article presents what is already being done with vibration sensors implanted in civil engineering structures and shows the potential interest of seismic metamaterials in this context. The modification of the surface signal by both structured soil and surface resonators meets the challenges of Civil Engineering through the effects of soil-structure interaction. Seismic metamaterials can therefore not only be considered for building protection, lensing and minimizing the effects of potentially deleterious Rayleigh waves, but also have potential applications in energy harvesting using ambient seismic noise.
