  • Patent number: 11818540
    Abstract: An acoustic sensor (e.g., for use in a piezoelectric MEMS microphone) includes a substrate and a cantilever beam attached to the substrate. The cantilever beam has a proximal portion attached to the substrate and a distal portion that extends from the proximal portion to a free end of the beam, the beam extending generally linearly from the proximal portion toward the free end in a first direction. The beam has a wall portion at or proximate the free end that extends in a second direction generally transverse to the first direction and increases an acoustic resistance of the gap between sensors. An electrode is disposed on or in the proximal portion of the beam.
