Cold sintering and electrical characterization of lead zirconate titanate piezoelectric ceramics
APL Materials, 2018 This paper describes a cold sintering process for Pb(Zr,Ti)O3 ceramics and the associated processing-property relations. Pb(Zr,Ti)O3 has a very small, incongruent solubility that is a challenge during cold sintering.

A theoretical analysis of a piezoelectric ultrasound device with an active matching layer [PDF]
, 2007 This paper investigates the use of magnetically active materials in the matching layer of a piezoelectric transducer. This then allows the performance of the device to be dynamically altered by applying an external field.

Enhanced electric-field-induced strains in (K,Na)NbO3 piezoelectrics from heterogeneous structures
, 2021 Piezoelectrics exhibit mechanical strain in response to electrical stimuli and vice versa. A high level of electric-field-induced strain with minimal hysteresis is desired for piezoelectric materials when used as actuators. The past two decades have seen
