A technology to move and levitate objects using just sound waves has been developed by researchers. The technique was demonstrated on small polystyrene balls that were lifted off a reflective surface without any physical contact. The reseachers fine-tuned the so-called acoustic tweezers using an adaptive algorithm and further miniaturisation, to make the technology mo...
