Lead-Free Piezoelectrics

Piezoelectric materials form the backbone of several components utilized in communication systems, defense systems, industrial automation, medical diagnostics, energy storage and harvesting, and information technology. In high performance piezoelectric applications the material of choice is based upon lead-based composition with Pb(Zr,Ti)O3 (PZT) being the base. Recently worldwide environmental considerations are demanding the elimination of lead-based materials from all the consumer items. This has created urgency for finding alternative to PZT. Elimination of lead in applications such as actuators still remains a challenge but in some other applications such as high frequency electronic components it has been possible to utilize lead-free materials. At a recent Electronic Materials and Applications 2011 meeting,.
