摘要： An example ultrasound device, such as a transducer array, includes a plurality of ultrasound transducers, each ultrasound transducer having a first electrode, a second electrode, a thin piezoelectric film located between the electrodes, and a substrate supporting the plurality of ultrasound transducers. In some examples, the electrode separation is less than 10 microns, facilitating lower voltage operation than conventional ultrasound transducers.
