Ultrasonic Manipulation is a technique that uses high-frequency sound waves to move and control small objects without physical contact. This method relies on the principles of acoustics, where sound waves create pressure fields that can exert forces on particles, droplets, or even cells. Researchers utilize ultrasonic waves to achieve precise positioning and manipulation in various applications, including microfluidics, biomedical engineering, and robotics. By adjusting the frequency and intensity of the sound waves, they can effectively control the movement and arrangement of materials at a microscopic scale.
