Exploring Optimal Ultrasonic Transducer Arrangements for Acoustic Levitation
Acoustic levitators can suspend low-density objects, with diameters less than half the wavelength of sound, in midair. Researchers have previously demonstrated that levitators can be constructed using easily acquirable electronics and materials. Such levitators are comprised of an array of ultrasonic transducers arranged in 3D printed structures. This versatile construction method allows for a great degree of control over a levitator’s acoustic pressure field. By modeling the physics of acoustic levitation, optimal designs were determined. Future work will prototype these optimized designs and test their capability for manipulating objects beyond the state-of-the-art.
