    • Acoustophoretic volumetric displays using a fast-moving levitated particle 

      Fushimi, Tatsuki; Marzo Pérez, Asier Upna; Drinkwater, Bruce W.; Hill, Thomas L. (AIP Publishing, 2019)   Artículo / Artikulua
      Displays have revolutionized the way we work and learn, and thus, the development of display technologies is of paramount importance. The possibility of a free-space display in which 3D graphics can be viewed from 360° ...
    • Automatic contactless injection, transportation, merging, and ejection of droplets with a multifocal point acoustic levitator 

      Andrade, Marco Aurélio Brizzotti; Camargo, Thales S. A.; Marzo Pérez, Asier Upna (AIP Publishing, 2018)   Artículo / Artikulua  OpenAccess
      We 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 

      Andrade, Marco Aurélio Brizzotti; Ramos, Tiago S.; Adamowski, Julio C.; Marzo Pérez, Asier Upna (American Institute of Physics, 2020)   Artículo / Artikulua
      We 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 

      Andrade, Marco Aurélio Brizzotti; Polychronopoulos, Spyros; Memoli, Gianluca; Marzo Pérez, Asier Upna (AIP Publishing, 2019)   Artículo / Artikulua  OpenAccess
      Single-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 ...
    • Exploring the addition of audio input to wearable punch recognition 

      Quintero Ovalle, Juan; Stawarz, Katarzyna; Marzo Pérez, Asier Upna (Association for Computing Machinery (ACM), 2019)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      Martial arts can promote healthy lifestyles, improve self-confidence and provide self-defence skills. Previous work has demonstrated that inertial sensors can be used to recognise movements such as punches in boxing and ...
    • Holographic acoustic elements for manipulating levitating particles. Applications in human-computer interaction 

      Marzo Pérez, Asier Upna (2016)   Tesis doctoral / Doktoretza tesia  OpenAccess
      En esta tesis doctoral demostramos simultáneamente atrapamiento 3D, traslación y rotación de las partículas utilizando dispositivos de una sola cara. Esto se logra mediante el ajuste de manera óptima los retardos de fase ...
    • Holographic acoustic elements for manipulation of levitated objects 

      Marzo Pérez, Asier Upna; Seah, Sue Ann; Drinkwater, Bruce W.; Sahoo, Deepak Ranjan; Long, Benjamin; Subramanian, Sriram (Nature Publishing Group, 2015)   Artículo / Artikulua  OpenAccess
      Sound can levitate objects of different sizes and materials through air, water and tissue. This allows us to manipulate cells, liquids, compounds or living things without touching or contaminating them. However, acoustic ...
    • Holographic acoustic tweezers 

      Marzo Pérez, Asier Upna; Drinkwater, Bruce W. (National Academy of Sciences, 2019)   Artículo / Artikulua  OpenAccess
      Acoustic tweezers use sound radiation forces to manipulate matter without contact. They provide unique characteristics compared with the more established optical tweezers, such as higher trapping forces per unit input power ...
    • Numerical and experimental investigation of the stability of a drop in a single-axis acoustic levitator 

      Andrade, Marco Aurélio Brizzotti; Marzo Pérez, Asier Upna (American Institute of Physics, 2019)   Artículo / Artikulua
      Acoustic 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 ...
