By optimizing the structure of acoustic voxels, Columbia Engineering researchers can control the acoustic response of an object when it is tapped and thereby tag the object acoustically. Given three objects with identical shapes, they can use a smartphone to read the acoustic tags in real-time, by recording and analyzing the tapping sound, and thereby identify each object.

Columbia Engineering researchers have developed a novel sheet camera that can be wrapped around everyday objects to capture images that cannot be taken with one or more conventional cameras. They designed and fabricated a flexible lens array that adapts its optical properties when the sheet camera is bent. This optical adaptation enables the sheet camera to produce high quality images over a wide range of sheet deformations.
