Acoustic levitation in mid-air: recent advances, challenges, and future perspectives
Brizzotti Andrade, Marco Aurélio; Marzo Pérez, Asier ; Adamowski, Julio C. (American Institute of Physics, 2020) Artículo / ArtikuluaMid-air acoustic levitation is becoming a powerful tool to suspend and manipulate millimetric objects. Because of its unique characteristics, acoustic levitation is suitable to trap a wide variety of materials such as ... -
Automatic contactless injection, transportation, merging, and ejection of droplets with a multifocal point acoustic levitator
Brizzotti Andrade, Marco Aurélio; Camargo, Thales S. A.; Marzo Pérez, Asier (AIP Publishing, 2018) Artículo / ArtikuluaWe present an acoustic levitation system that automatically injects, transports, merges and ejects liquid droplets in mid-air. The system consists of a phased array operating at 40 kHz on top of a plane reflector. The phase ... -
Contactless pick-and-place of millimetric objects using inverted near-field acoustic levitation
Brizzotti Andrade, Marco Aurélio; Ramos, Tiago S.; Adamowski, Julio C.; Marzo Pérez, Asier (American Institute of Physics, 2020) Artículo / ArtikuluaWe model and realize an ultrasonic contactless pick-and-place device capable of picking, self-centering, self-orienting, translating, and releasing flat millimetric objects. The device is an ultrasonic Langevin transducer ... -
Experimental investigation of the particle oscillation instability in a single-axis acoustic levitator
Brizzotti Andrade, Marco Aurélio; Polychronopoulos, Spyros; Memoli, Gianluca; Marzo Pérez, Asier (AIP Publishing, 2019) Artículo / ArtikuluaSingle-axis acoustic levitators are employed in biomedicine, chemistry and physics experiments due to their ability to trap in mid-air objects of a wide range of materials and sizes. Although this type of levitator has ... -
Numerical and experimental investigation of the stability of a drop in a single-axis acoustic levitator
Brizzotti Andrade, Marco Aurélio; Marzo Pérez, Asier (American Institute of Physics, 2019) Artículo / ArtikuluaAcoustic levitation can be employed to hold liquid drops in midair, enabling novel applications in X-ray scattering of proteins, amorphous crystallization of solutions, or contactless mixing. Multiple studies have characterized ...
