Information has appeared online about a new invention by scientists from the University of Zurich that allows you to hold
As the technology that formed the basis“Invader”, ultrasound was used. According to engineers, a revised version of their invention will be able to allow robots to manipulate various objects at the most delicate level. So, thanks to a whole array of miniature speakers emitting sound at very carefully controlled frequencies and volumes, a “pressure wave” is created that holds the object and also, if necessary, moves it.
Interestingly, the so-called “acoustic levitation” technique is not so new, but despite this, researchers until the last could not put it into practice.
