ABSTRACT
In this talk, we show how acoustic metamaterials can be used to build the acoustic equivalent of optical devices. We demonstrate two key devices: (1) an acoustic prism, used to send the different notes in a melody towards different directions, and (2) an auto-zoom lens, used to send sound to a moving target. We conclude, discussing potential applications and limitations.

VARI-SOUND: A Varifocal Lens for Sound
CHI '19: Proceedings of the 2019 CHI Conference on Human Factors in Computing SystemsCenturies of development in optics have given us passive devices (i.e. lenses, mirrors and filters) to enrich audience immersivity with light effects, but there is nothing similar for sound. Beam-forming in concert halls and outdoor gigs still requires ...
Hybrid gold-copper stamp for rapid fabrication of microchips
Graphical abstractDisplay Omitted Highlights We have developed simple and low-cost fabrication method of metal stamps. The stamps are intended for fast and cheap replication of microfluidic structures. Inherent metal hardness allows hundreds of ...
Direct fabrication of microstructures on metal roller using stepped rotating lithography and electroless nickel plating
Roller embossing has attracted more attention in recent years due to its rapid and continuous process for mass production. The fabrication of roller is a challenge due to microstructures on the curved surface. This paper proposes a method of fabricating ...
