Dual-frequency piezoelectric micromachined ultrasound transducer based on polarization switching in ferroelectric thin films
Abstract Due to its additional frequency response, dual-frequency ultrasound has advantages over conventional ultrasound, which operates at a specific frequency band. Moreover, a tunable frequency from a single transducer enables sonographers to achieve ultrasound images with a large detection area...
