  • Integrated Acoustic Devices
    Publication number: 20230387877
    Abstract: Method for forming an integrated acoustic device. A thin film piezoelectric acoustic transducer is epitaxially formed on a host substrate and is then transferred to a functional target substrate wherein physical phenomena from the piezoelectric transducer and the arbitrary functional substrate interact to form a hybrid acoustic microsystem comprising the piezoelectric transducer and the arbitrary functional substrate.
    Type: Application

    Publication date: November 30, 2023
    Applicant: The Government of the United States of America, as represented by the Secretary of the Navy
    Inventors: Vikrant J. GOKHALE, Brian P. DOWNEY, Shawn C. MACK, D. Scott KATZER, David J. MEYER, Pallavi DHAGAT, Albrecht JANDER
  • Multifunctional integrated acoustic devices and systems using epitaxial materials
    Patent number: 11831295
    Abstract: Acoustic wave devices based on epitaxially grown heterostructures comprising appropriate combinations of epitaxially grown metallic transition metal nitride (TMN) layers, epitaxially grown Group III-nitride (III-N) piezoelectric semiconductor thin film layers, and epitaxially grown perovskite oxide (PO) layers. The devices can include bulk acoustic wave (BAW) devices, surface acoustic wave (SAW) devices, high overtone bulk acoustic resonator (HBAR) devices, and composite devices comprising HBAR devices integrated with high-electron-mobility transistors (HEMTs).

  • Micromechanical vibrasolator
    Patent number: 11050405
    Abstract: A micromechanical vibrasolator isolates vibration of a micromechanical resonator and includes: phononic bandgap mirrors, monophones connected serially; phonophore arms in an alternating sequence of phonophore arm-monophone-phonophore arm; abutments in acoustic communication with the phononic bandgap mirrors; wherein the micromechanical resonator is interposed between the phononic bandgap mirrors with phononic bandgap mirror arranged in parallel on opposing sides of the micromechanical resonator arranged perpendicular to a direction of vibration of an in-plane vibrational mode of the micromechanical resonator.
