It is this property of ultrasound that the researchers have tapped to create 3D haptic shapes in mid-air -- users can feel those air disturbances on the skin. Moreover, those patterns can be ...

A new technique being developed by researchers at the University of Bristol promises to change all of this by using projected ultrasound to directly create floating, 3D shapes that can be seen and ...

Computer scientists from the University of Bristol have devised a machine that generates floating 3D shapes that you can feel, but can't see. The possibilities that such a technology would enable ...

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.

[Ben Bartlett] recently got engaged, and the proposal had a unique bit of help in the form of a 3D-printed hexagonal mirror array, whose mirrors are angled just right to spell out a message with th… ...

Three-dimensional (3D) imaging is essential for investigating cellular structure and dynamics. Traditional optical methods ...

Scientists from The Hebrew University of Jerusalem have created wood ink that can be extruded into flat wooden structures, self-morphing into complex 3D shapes as they dry and shrink.
