Here's How Scientists Move Things Without Using Their Hands

The mysterious character called had the ability to move objects with her mind without touching them in the critically acclaimed Netflix series.Although such a thing isn't realistic in real life, people may be able to move objects in the near future without ever touching them.Researchers at the University of Maryland have developed a new way of handling materials hands-free using ultrasound waves, a peer-reviewed, open-access journal.This time, researchers expanded on the previous findings by developing a new method that allows for larger objects to be moved using the metamaterial physics model.Metamaterials are materials that are artificially engineered to interact with waves, such as light and sound.

I think they were charting in a new direction here, showing that we cannot move objects without physical contact, and that motion can be controlled simply by controlling what is on the surface of the object.Mr Ilic posted a new way to contactless actuate things.Featured Video Of The Day: Watch: Lalu Yadavs video retort after a Kidney Transplant Surgery.
