Multi-functional single-source acoustic tweezer

Acoustic tweezers have gained considerable attention due to their potential and important role in various applications. A costeffective and precise method for manipulating particles is using 3D-printed acoustic holographic lenses. However, this technique is limited in its determined function for particle manipulation with a single holographic lens. We propose a method to overcome this limitation by constructing a multi-functional acoustic tweezer, which is capable of achieving diverse functions of particle manipulation. We demonstrate the ability to achieve fixed-angle rotation of a rectangular particle, multi-pattern particles arrangement, selectable left-right movement of a particle on a line, and completing two distinct trajectories with a single particle.Our proposed method offers a flexible and real-time controlling approach for acoustic tweezers, which can partially substitute the phased arrays with high circuit complexity.
