Problems solved by technology

In these existing technologies, although the control particle system involved has some progress compared with the previous technology, the medium in which the particles are manipulated is also a homogeneous medium
In a heterogeneous medium, it is still difficult to manipulate particles
This is due to the complex scattering and refraction of

Abstract

The invention relates to the technical field of acoustic control, in particular to a particle control system and a method based on a time reversal technology. The system and the method aim at achieving any path control for a particle in a nonuniform medium. Therefore, the particle control system based on the time reversal technology is characterized by comprising an array probe, a signal reception and transmission control device and an upper computer, wherein the array probe is in communication connection with the signal reception and transmission control device; and the signal reception and transmission control device is in communication connection with the upper computer. Therefore, the system can be applied in the fields of in-vivo fixed-point administration, reproductive medicine and the like and have a higher practical value. The invention further provides the particle control method using the time reversal technology.

Description

technical field [0001] The present invention generally relates to the technical field of acoustic manipulation, and in particular to a system and method for manipulating particles based on time reversal technology. Background technique [0002] As a kind of mechanical wave, sound wave can exchange momentum and energy with particles in the sound field, generate sound radiation force, and control the movement of particles. This technology has been applied to many fields such as physics, chemistry, biology, etc., and has attracted widespread attention because of its advantages of non-contact, non-damage, and good biocompatibility. The current sound control technology and devices are mainly aimed at manipulating objects in a homogeneous medium (water, air) with uniform acoustic parameters such as density and sound velocity. sound field profile. However, the non-uniform distribution of parameters such as density and sound velocity in complex heterogeneous media (such as the hum...
