Ferroelectrics for Biomedical Applications

Abstract

Recently, many other advanced ceramics have been developed rapidly. Chen et al. [6] reported the use of extrusion technique to fabricate transparent lead lanthanum zirconate titanate (PLZT) ceramic fibers. The final transducer was housed in an SMA connector for poling and pulse-echo measurement. The ceramic fibers can been used to create the small aperture ultrasonic transducer. And it has a great potential in photoacoustic imaging by using the transparent fiber as the path of light propagation and ultrasonic transducer materials.Researchers also [7] investigated the design, fabrication, and experimental evaluation of a prototype PZT matrix transducer with an integrated receive Application Specific Integrated Circuit (ASIC) on what consists of an array of 9 × 12 piezoelectric
