Printable piezoelectric materials have been under development over the recent years due to their great potential in several fields of application, covering both low- and high-frequency devices. Meggitt A/S has been one of the players in the field through its development of a screen- and pad-printable PZT thick film material (TF2100) as well as the composite material PiezoPaint. Printable PZT (Lead Zirconate Titanate) thick films have already been successfully commercialized; however, due to the recent initiatives at EC under the RoHS directive, Lead-Free thick films have been also investigated, and an ultrasonic imaging transducer based on piezoelectric lead-free thick film has been demonstrated.
