A capacitive transducer is provided. The capacitive transducer includes a plate including a protruding center mass and a substrate with a center depression configured to accept the center mass. The capacitive transducer also includes a first electrode coupled to a non-horizontal edge surface of the center mass and a second electrode coupled to a non-horizontal edge surface of the center depression. The capacitive transducer further includes a third electrode coupled to a horizontal edge surface of the center mass and a fourth electrode coupled to a horizontal edge surface of the center depression. The plate is coupled to the substrate at least along an outer perimeter area of the plate and the substrate.

Micromachined ultrasonic transources with dual out-of-plane and in-plane actuation and displacement

A micromachined ultrasonic transducers with non-coplanar actuation and displacement comprising a plate with a protruding center mass, a substrate with a center depression configured to accept the center mass, a first electrode coupled to a non-horizontal edge surface of the center mass, and a second electrode coupled to a non-horizontal edge surface of the center depression. The plate may be coupled to the substrate at least along an outer perimeter area of the plate and the substrate.

A capacitive transducer comprising a top electrode and a bottom electrode, and a sidewall between the top electrode and the bottom electrode. The sidewall is configured to separate the top electrode and the bottom electrode by a gap. There is a high contact resistance part on one or both of a bottom side of the top electrode or a top side of the bottom electrode.
