(PhysOrg.com) -- Researchers from the University of Tokyo have developed 3D holograms that can be touched with bare hands. Generally, holograms can't be felt because they're made only of light. But the new technology adds ...
(PhysOrg.com) -- In 2008, scientists built a loudspeaker made of carbon nanotubes that produced sound and music based on the thermoacoustic effect. Now, a different team of scientists has built a loudspeaker made of tiny ...
Sound can now be structured in three dimensions. Researchers from the Max Planck Institute for Intelligent Systems and the University of Stuttgart have found a way of generating acoustic holograms, which could improve ultrasound ...
