The ability of producing ultrasonic transducers from screen-printing has been exploredexperimentally, through printing and characterization of a large number of transducers. In an allprintedtest design, 124 transducers with four different electrode sizes ranging from 1 to 4.9 mm2,were printed layer-by-layer on a high performance polyethyleneimine polymer. Inks fromferroelectric and conductive polymers were applied to the active part of a transducer, to provide agood acoustical match between the individual layers. Ultrasonic characterizations of thetransducers done by two independent methods provided a broad-banded frequency response with amaximum response around 100 MHz
