Thanks to sound waves, scientists don’t even need hands anymore

September 10th, 2020

Researchers from Duke University have developed a new kind of ‘acoustic tweezers’ that allows for the manipulation of tiny objects in a Petri dish without using your hands. Systems like this are typically very complicated and have not seen widespread use. The researchers hope to make their system simple and affordable enough to commercialize it. …

This incredible sound wave system can make particles levitate

December 18th, 2018

We’ve already seen sound waves do some pretty amazing things. For example, they can turn a regular, boring stream of water into a mesmerizing work of moving art, and even cause small particles to float in mid-air. Now, researchers have developed a powerful sound wave system that not only causes objects to seemingly defy gravity, but …
