Kolar Power Electronic Systems Laboratory, ETH Zurich, Switzerland, Physikstrasse 3, 8092 Zurich, Switzerland; [email protected] (M.S.); [email protected] (L.K.); [email protected] (J.W.K.) * Correspondence: [email protected] † This paper is an extended version of our paper published in the 1st International Electronic Conference on Actuator Technology: Materials, Devices and Applications (IeCAT), 23–27 November 2020. Abstract: Acoustic levitation forces can be used to manipulate small objects and liquids without mechanical contact or contamination. This work presents analytical models based on which concepts for the controlled insertion of objects into the acoustic field are developed. This is essential for the use of acoustic levitators as contactless robotic grippers. Three prototypes of such grippers are implemented and used to experimentally verify the lifting of objects into an acoustic pressure field. Lifting of high-density objects (r > 7 g/cm3) from acoustically transparent surfaces is demonstrated using a double-sided acoustic gripper that generates standing acoustic waves with dynamically adjustable acoustic power. A combination of multiple acoustic traps is used to lift lower density objects (r ≤ 0.25 g/cm3) from acoustically reflective surfaces using a single-sided arrangement. Furthermore, a method that uses standing acoustic waves and thin reflectors to lift medium-density objects (r ≤ 1 g/cm3) from acoustically reflective surfaces is presented. The provided results open up new possibilities for using acoustic levitation in robotic grippers, which has the potential to be applied in a variety of industrial use cases.

Foresti, M. Nabavi and D. Poulikakos† Department of Mechanical and Process Engineering, Institute of Energy Technology, Laboratory of Thermodynamics in Emerging Technologies, ETH Zurich, CH-8092, Zurich, Switzerland (Received 3 April 2012; revised 4 June 2012; accepted 3 July 2012; first published online 31 August 2012) We present here an in-depth analysis of particle levitation stability and the role of the https:/www.cambridge.org/core/terms radial and axial forces exerted on fixed spherical and ellipsoidal particles levitated in an axisymmetric acoustic levitator, over a wide range of particle sizes and surrounding medium viscosities. We show that the stability behaviour of a levitated particle in an axisymmetric levitator is unequivocally connected to the radial forces: the loss of levitation stability is always due to the change of the radial force sign from positive to negative. It is found that the axial force exerted on a sphere of radius Rs increases with increasing viscosity for Rs/λ < 0:0125 (λ is the acoustic wavelength), with the viscous contribution of this force scaling with the inverse of the sphere radius. The axial force decreases with increasing viscosity for spheres with Rs/λ > 0:0125. The radial force, on the other hand, decreases monotonically with increasing viscosity. The radial and axial forces exerted on an ellipsoidal particle are larger than those exerted on a volume-equivalent sphere, up to the point where the ellipsoid starts to act as an obstacle to the formation of the standing wave in the levitator chamber.

  • Frequency Selective Wave Beaming in Nonreciprocal Acoustic Phased Arrays Revant Adlakha1,3, Mohammadreza Moghaddaszadeh2,3, Mohammad A
    www.nature.com/scientificreports OPEN Frequency selective wave beaming in nonreciprocal acoustic phased arrays Revant Adlakha1,3, Mohammadreza Moghaddaszadeh2,3, Mohammad A. Attarzadeh1,3, Amjad Aref2 & Mostafa Nouh1* Acoustic phased arrays are capable of steering and focusing a beam of sound via selective coordination of the spatial distribution of phase angles between multiple sound emitters. Constrained by the principle of reciprocity, conventional phased arrays exhibit identical transmission and reception patterns which limit the scope of their operation. This work presents a controllable space–time acoustic phased array which breaks time-reversal symmetry, and enables phononic transition in both momentum and energy spaces. By leveraging a dynamic phase modulation, the proposed linear phased array is no longer bound by the acoustic reciprocity, and supports asymmetric transmission and reception patterns that can be tuned independently at multiple channels. A foundational framework is developed to characterize and interpret the emergent nonreciprocal phenomena and is later validated against benchmark numerical experiments. The new phased array selectively alters the directional and frequency content of the incident signal and imparts a frequency conversion between diferent wave felds, which is further analyzed as a function of the imposed modulation. The space–time acoustic phased array enables unprecedented control over sound waves in a variety of applications ranging from ultrasonic imaging to non-destructive testing and underwater SONAR telecommunication. In their most general form, phased arrays can be thought of as a coalescence of multiple wave transmitting/ receiving components—also known as transceivers—which share a common excitation/collection port. Te hallmark feature of phased arrays, setting them apart from antennas, is an additionally imparted phase angle on each of its individual transceivers.

  • Researchers Demonstrate Acoustic Levitation of a Large Sphere 12 August 2016, by Lisa Zyga
    Researchers demonstrate acoustic levitation of a large sphere 12 August 2016, by Lisa Zyga paper on the acoustic levitation demonstration in a recent issue of Applied Physics Letters. "Acoustic levitation of small particles at the acoustic pressure nodes of a standing wave is well-known, but the maximum particle size that can be levitated at the pressure nodes is around one quarter of the acoustic wavelength," Andrade told Phys.org. "This means that, for a transducer operating at the ultrasonic range (frequency above 20 kHz), the maximum particle size that can be levitated is around 4 mm. In our paper, we demonstrate that we can combine multiple ultrasonic transducers to levitate an object significantly larger than the acoustic wavelength. In our experiment, we could increase the maximum object size from one quarter of the wavelength to 50 mm, which is approximately Acoustic levitation of a polystyrene sphere, the first 3.6 times the acoustic wavelength." spherical object to be acoustically levitated that is larger than the acoustic wavelength.

Many ultrasound capture devices were developed according to this principle, which works when sound waves of the same frequency are on opposite sides and are placed on top of each other. That is, they need two sets of converters to float the particles. Acoustic beam tractor is an innovative technology that can be used to fix and use objects in air, water and human tissues with a large number of ultrasound emitters. It requires sound waves from the other side to detect particles. Acoustic beam technology is promising in a variety of fields. It can be used to harvest and decompose particles within the body such as kidney stones, clots, tissues and even target delivery drugs. The technology has some promising systems in the outer space, where they can stop large objects with gravity and prevent them from moving unmanageable.

  • Particle Manipulation by a Non-Resonant Acoustic Levitator By: Azeem Iqbal Lab Instructor, Physics Department SBASSE, LUMS Acoustic Levitation
    Particle manipulation by a non-resonant acoustic levitator by: Azeem Iqbal Lab Instructor, Physics Department SBASSE, LUMS Acoustic levitation Let’s first watch a video … Contents • What is acoustic levitation? • Brief historical background • Current applications • Particle manipulation by a non-resonant acoustic levitator – Concept – Hardware & Construction – Mathematical Model – Simulation – Conclusion What is acoustic levitation? • Acoustic levitation (also: Acoustophoresis) is a method for suspending matter in a medium by using acoustic radiation pressure from intense sound waves in the medium. • “Acoustophoresis” means migration with sound, i.e., “phoresis” – migration and “acousto” – sound waves are the executors of the movement. What is acoustic levitation? • To understand how acoustic levitation works: – First know that gravity is a force that causes objects to be pulled towards the earth. – Second, air is a fluid and like liquids, air is made of microscopic particles that move in relation to one another. – Third, sound is a vibration from a sound's source and as it moves or changes shape very rapidly it creates oscillations creating sound. A series of compressions and rarefactions. Each repetition is one wavelength of the sound wave. • Acoustic levitation uses sound traveling through a fluid (air) to balance the force of gravity. Physics of Sound Levitation • A basic acoustic levitator has two main parts – – a transducer, which is a vibrating surface that makes sound, – and a reflector. • A sound wave travels away from the transducer and bounces off the reflector. Physics of Sound Levitation • The interaction between compressions and rarefactions causes interference. • Compressions that meet other compressions amplify one another, and compressions that meet rarefactions balance one another out.

  • Acoustic Levitation
    Acoustic Levitation Jason Yang, Michael Redlich Experiment March 13th through April 24th Abstract Acoustic Levitation is recently developed experiment based on acoustic pressure counteracting gravity. We used ultrasonic transducer to provide sound pressure because it is in inaudible range with optimized pressure. A reflector plate set opposite of the transducer provides a standing wave when located at the correct distance. Styrofoam bits are used as levitation material because they are relatively light and have larger surface. Using the described design we tested several properties of acoustic levitation systems. We discovered that the curvature of the reflector plate did little to change the system, that we could create up to seven nodes, and that new properties emerged when we used a double transducer setup. However, the pressure microphone was unable to record data on the ultrasonic device, so we used computer simulation called COMSOL to see the theoretical pressure field. I. Introduction With a transducer connected to a driver board placed on a table and a reflector plate overhead we had designed a simple mechanism for acoustically levitating small, low density, materials. Using (nonmetal) tweezers we carefully placed small bits of Styrofoam that we had shredded earlier into the acoustic beam. Most of the time we failed to levitate the object. Largely this was due to the empirical nature of the setup; without accurate measurements from the oscilloscope we were unable to determine whether or not we had a standing wave so we had to make small adjustments to the height of the reflector plate and continue placing objects into the beam with the tweezers until we were successful.

P4 Department of Mechatronics Engineering Akshaya College of Engineering and Technology, India Abstract: Acoustic Levitation is a method of suspending matter in a medium of air using Acoustic radiation pressure from intense sound wave in the medium. An acoustic levitation system is presented in this paper which can levitate planar objects much larger than the wavelength of the applied sound wave. It uses standing wave field formed by the sound radiator and the levitated planar object. An experimental setup is developed, by which a compact disc is successfully levitated at frequency of 40 kHz. The sound field is modeled according to acoustic theory. The mean excess pressure experienced by the levitated object is calculated and compared with experiment results. Nonlinear absorption coefficient is introduced into the linear model to give a more precise description of the system. The levitation force is calculated for different levitation distances and driving frequencies. The calculation results show acceptable agreement with the measurement results.

Abstract: High frequency Sound waves can create oscillating packets of pressurized air, which can generate a force on particles capable of counteracting the pull of gravity. Many ultrasound levitation devices are developed based on this principle, which are working when two sound waves of the same frequency are emitted from opposite directions and superimposed on one another. That is, they require two sets of transducers to float the particles. Acoustic tractor beam is an emerging technology that can be applied to levitate and manipulate objects in air, water and human tissues with a single array of ultrasound emitters. It requires sound waves from one side to levitate particles. Acoustic tractor beam technology holds promise in a variety of fields. It can be applied for levitating and manipulating particles inside the body like kidney stones, clots, tumors and even capsules for targeted drug delivery. The technology also has some promising applications in outer space, where it can suspend larger objects in lower gravity and prevent them from drifting around uncontrolled. Keywords: acoustic hologram, tractor beam, transducers, tweezers, trap I. Introduction When we stand in front of a loud speaker we can perceive the force from sound waves. We can experience our bodies shake with the loud sound.
