In 2018, Arthur Ashkin won the Nobel Prize in Physics for inventing optical tweezers: laser beams that can be used to manipulate microscopic particles. While useful for many biological applications, ...

A study published last month by University of Minnesota mechanical engineering researchers has the potential to make waves – ultrasonic waves, to be exact – in fields like surgery and manufacturing. U ...

Over the past several decades, scientists have developed optical and acoustic tweezers. Using light or sound waves, they can lift and control the motion of a small object, like a tiny tractor beam.

TORONTO (CTV Network) — Researchers at Tokyo Metropolitan University have created ‘tweezers of sound’ that can move objects without physical contact. The technology creates non-contact manipulation of ...

Engineers at the University of Minnesota have developed a new system that can move objects without making physical contact. The technique involves ultrasound waves acting on specialized surfaces to ...

No smoke, no mirrors, just sound was all scientists needed to levitate objects in midair. NPR reports that researchers at the University of Tokyo have discovered a new levitation technique through ...

The ultimate goal to making virtual reality feel more like reality is letting users physically touch non-existent objects in a VR world. Until we figure out the technology behind Star Trek’s Holodecks ...
