Transmissive Labyrinthine Acoustic Metamaterial‐Based Holography for Extraordinary Energy Harvesting

A transmissive labyrinthine acoustic metamaterial sidewalk barrier focuses the sound energy from street vehicles onto a harvester attached to the outside of the building. This ubiquitous and often wasted sound energy can power a myriad of power-based devices like IoT across the urban environment.
