For any fan of Doctor Who, the invention of a working sonic screwdriver is the ultimate wet dream. Now that dream has been turned into reality through the hard work of researchers at the University of Bristol.
They achieved this by using multiple focused sound waves to pin objects in place in mid-air. While acoustic levitation is not a new technology, this is however the first application of multiple acoustics being used for this sort of purpose.
The team believes that this technology could be used for applications in tractor beams, container-less handling of matter and tangible displays. In addition, this technology could also be utilized for medical purposes, allowing professionals to manipulate cells, liquids, compounds or living things without touching or contaminating them.
The invention of sonic screwdrivers, levitation gauntlets and ultra tongs are just proof of concepts when compared to all the future prospects of this technology. However getting these proof of concepts ready was a big part of the struggle.
From here, it’s only a matter of time before we see this technology getting adopted by various fields, fundamentally changing the way we interact with matter.
If you are a Doctor Who fan, or just a fan of amazing science in general, then you can take a look at this video demonstration showcasing these achievements, as well as read all the findings in the Nature Journal.
