High performance single crystal piezoelectrics: applications and issues

Relaxor-based single crystal piezoelectrics began to live up to their promise of providing unprecedented increase of bandwidth, sensitivity and high energy density for advanced piezoelectric transducers and actuator applications. Large size crystals are now available, at reduced cost, for device fabrication and performance tests. The newly gained insights from related investigations opened new opportunities for developing novel piezoelectrics. (C) 2002 Elsevier Science Ltd. All rights reserved.
