  • Publication number: 20220250072
    Abstract: Articles of manufacture, including an apparatus for omnidirectional spiral surface acoustic wave generation, are provided. An acoustic wave device that generates a plurality of acoustic wave includes a piezoelectric material to convert electric energy into the plurality of acoustic waves. The acoustic wave device also includes a transducer. The transducer includes a plurality of fingers arranged in a spiral formation. The plurality of acoustic waves induce acoustic streaming along the piezoelectric material in multiple directions to isolate a fluid component within a fluid located on the acoustic wave device.

  • Publication number: 20220211977
    Abstract: A hydraulically driven surgical apparatus may be a tube enclosing a first channel filled with a first fluid. Changing a fluid pressure in the first channel may trigger a deformation of the tube. The deformation of the tube may perform an action associated with a surgical procedure. Related methods for steering a hydraulically driven surgical apparatus are also provided.

  • Publication number: 20200164398
    Abstract: Articles of manufacture, including an apparatus for acoustic wave based atomization, are provided. The apparatus may include a monocrystalline piezoelectric substrate. The monocrystalline piezoelectric substrate may include a surface patterned with at least one wetting region. The monocrystalline piezoelectric substrate may be configured to respond to an electric signal by at least generating acoustic waves including, for example, surface acoustic waves, Bluestein-Gulayev waves, Lamb waves, Love waves, flexural waves, thickness mode vibrations, mixed-mode waves, longitudinal waves, shear mode vibrations, and/or bulk wave vibrations. The acoustic waves may atomizing at least a portion of a material collected within the at least one wetting region to form a mist of the material. Methods for acoustic wave based atomization are also provided.
