Air-coupled transducers with broad bandwidth are desired for many airborne applications such as obstacle detection, haptic feedback, and flow metering. In this paper, we present a design strategy and demonstrate a fabrication process for developing improved concentric annular- and novel spiral-shaped capacitive micromachined ultrasonic transducers (CMUTs) that can generate high output pressure and provide wide bandwidth in air. We explore the ability to implement complex geometries by photolithographic definition t
