Self-Navigated 3D Acoustic Tweezers in Complex Media Based on Time Reversal

In this study, we created a 1. 04 MHz 256-element 2D matrix variety for 3D acoustic tweezers to assist and keep track of the whole procedure using real-time 3D ultrasonic photos, therefore enabling acoustic manipulation in nontransparent media. We accomplished 3D fragment manipulation in heterogeneous media by introducing an approach based on the time reversal concept to fix the stage and amplitude distortions of the acoustic waves.

Three-Dimensional Trapping and Dynamic Axial Manipulation with Frequency-Tuned Spiraling Acoustical Tweezers: A Theoretical Study

Holographic acoustical tweezers based on Archimedes-Fermat spiraling interdigitated transducers are a versatile tool for the discerning adjustment of microparticles [Baudoin et al. , Sci. Here we reveal through a theoretical research that a 3D radiation trap for cells and microparticles can be acquired with spiraling tweezers with completely huge aperture and that the bits can be displaced axially by just tuning the driving regularity, without any kind of movement of the transducer.
