Abstract: Piezoelectric micromachined ultrasonic transducers (PMUTs) traditionally operate at a single frequency, requiring physical modifications to alter their operational frequency. In ultrasonic ...

Ultrasound applications in imaging and neuromodulation are limited by the bulkiness and narrow bandwidth of conventional transducers, as well as nonlinear distortion from bipolar pulse cancellation.

Ultrasound, or ultrasonic waves, are acoustic pressure waves that travel at frequencies of over 20 kilohertz (20,000 cycles ...

IRT Jules Verne, working with Airbus, Daher and French consortium developed a mobile robotic inspection platform that uses ...
