2021 21st International Conference on Solid-State Sensors, Actuators and Microsystems (Transducers).
This paper describes the further development of large area (13x13 mm2) polymer PMUT arrays operating at relatively low frequency (233.4 kHz) for mid-air imaging applications. An improved frequency uniformity across more elements enables an output eff
