"Tractor beam" grabs beads with sound waves
29 October 2015
Engineers in Bristol have developed a system that can grab, hold, and move small objects without touching them, using "holograms" made of sound waves. Prof Bruce Drinkwater from the University of Bristol, one of the study's authors, said the holy grail in this field is to use this sort of manipulation in, for example, targeted drug delivery.
"Our method, we hope, will now be applied, both at a smaller scale – maybe for medical purposes – and at a larger scale, potentially for handling dangerous materials in some sort of non-contact production line."
