Abstract

The aim of this research is to produce 2-2 PZT/polymer composite using tape casting technology. PZT tapes were printed with a fugitive phase (carbon) to define voids which were then backfilled with epoxy after the carbon was removed by thermal treatment at 1250°C. Final dimensions of the 2-2 composite were in the range of 25 μm for the ceramic bar and 5 μm for the epoxy-filled kerf. Specific emphasis was placed on achieving uniformity and straightness of the ceramic beam and kerf thicknesses. The composites were fabricated into 20 MHz single element pachymeters and benchmarked against commercial devices fabricated by dice-and-fill. The tape cast material compared favorablely with high sensitivity and a little lower bandwidth. Fabrication of a 35 MHz linear array transducer is in progress. Electrode patterning to define individual array elements has been successfully completed.
