Sound waves are actually waves of physical pressure. We’ve used them in haptics technology to create invisible, touchable shapes in midair. Manipulating waves in 3D requires a phased array of transducers, but phased arrays are limited in spatial resolution by the physical size of each transducer. They’re also expensive. Now […]

Researchers discover how to shape sound in 3D
