Enhanced torsional actuation and stress coupling in Mn-modified 0.93(Na(0.5)Bi(0.5)TiO(3))-0.07BaTiO(3) lead-free piezoceramic system

This paper is concerned with the development of a piezoelectric d (15) shear-induced torsion actuator made of a lead-free piezoceramic material exhibiting giant piezoelectric shear stress coefficient (e (15)) and piezoelectric transverse shear actuation force comparable to that of lead-based shear-m...

description This paper is concerned with the development of a piezoelectric d (15) shear-induced torsion actuator made of a lead-free piezoceramic material exhibiting giant piezoelectric shear stress coefficient (e (15)) and piezoelectric transverse shear actuation force comparable to that of lead-based shear-mode piezoceramics. The Mn-modified 0.93(Na(0.5)Bi(0.5)TiO(3))-0.07BaTiO(3) (NBT-BT-Mn) composition exhibited excellent properties as a torsional transducer with piezoelectric shear stress coefficient on the order of 11.6 C m(–2). The torsional transducer, consisting of two oppositely polarized NBT-BT-Mn d (15) mode piezoceramic shear patches, provided a rate of twist of 0.08 mm m(–1) V(–1) under quasi-static 150 V drive. The high value of piezoelectric shear d (15) coefficient in NBT-BT-Mn sample further demonstrated its potential in practical applications. These results confirm that the lead-free piezoceramics can be as effective as their lead-based counterparts.
