3D Printing and processing of miniaturized transducers with near-pristine piezoelectric ceramics for localized cavitation

Abstract: The performance of ultrasonic transducers is largely determined by the piezoelectric properties and geometries of their active elements. Due to the brittle nature of piezoceramics, existing processing tools for piezoelectric elements only achieve simple geometries, including flat disks, cylinders, cubes and rings. While advances in additive manufacturing give rise to free-form fabrication of piezoceramics, the resultant transducers suffer from high porosity, weak piezoelectric responses, and limited geometrica… Show more

“…[ 151 ] For example, the 3D‐printed dense piezoelectric elements achieve high piezoelectric properties ( d 33 = 583 pC N −1 and k t = 0.57) and complex architectures for localized cavitation (Figure 4h–j). [ 152 ] The utilization of 3D printing technology in the production of package components allows for the adjustment of acoustic properties, thereby enabling the adaptation of PZT elements to various transmission media and applications. This enhances the adaptability of the ultrasound transducers manufactured through this process, particularly in the field of medical treatments.…”
