Aspects of this disclosure relate to driving a capacitive micromachined ultrasonic transducer (CMUT) with a pulse train of unipolar pulses. The CMUT may be electrically excited with a pulse train of unipolar pulses such that the CMUT operates in a continuous wave mode. In some embodiments, the CMUT may have a contoured electrode.

Pulse train excitation for capacitive micromachined ultrasonic transducer

Aspects of this disclosure relate to a capacitive micromachined ultrasonic transducer (CMUT) with a contoured electrode. In certain embodiments, the CMUT has a contoured electrode. The electrode may be non-planar to correspond to a deflected shape of the outer plate. A change in distance between the electrode and the plate after deflection may be greater than a minimum threshold across the width of the CMUT.
