Three dimensional acoustic tweezers with vortex streaming | ResearchBunny

Abstract

Acoustic tweezers use ultrasound for contact-free manipulation of particles. This paper demonstrates a 3D acoustic tweezer using a single transducer, combining radiation force for 2D trapping with streaming force for levitation. Simulation and experiments at 500 kHz show levitation force three orders of magnitude larger than previous 3D traps, expanding the range of manipulatable particles.
