Abstract
The Micropen¿ direct-write technique was used to fabricate ceramic skeletal structures to develop ceramic/polymer (2-2) composites for high frequency transducers in medical imaging applications. Both regular and volume fraction gradient (VFG) patterns were designed. By this approach, transducers were fabricated with 1 cm2 transduction area, operating at 4¿5 MHz. The composites had ~30 vol% of ceramic, with thickness ranging 290 to 380 ¿m. They had a dielectric loss of 2.0¿2.1%, a dielectric constant of 500¿670, a d33 of 190, and kt of 56%¿61%.
