Cylindrical Micro Ultrasonic Motor Utilizing Bulk Lead Zirconate Titanate (PZT)
Ultrasonic motors are expected to be used as microactuators because of their high torque, low speed and simple construction. We have already reported cylindrical-shaped micro ultrasonic motors which utilized a lead zirconate titanate (PZT) thin film. In this paper, we discuss a micro ultrasonic motor composed of bulk PZT. The stator transducer had dimensions of 2.4 mm in diameter and 10 mm leng...
متن کاملA Ferroelastic Switching Model for Lead Zirconate-Titanate (PZT)
This paper develops a macroscopic polarization switching model which characterizes the ferroelastic switching mechanisms inherent to lead zirconate-titanate (PZT) in a manner suitable for subsequent transducer and control design. We construct Helmholtz and Gibbs energy relations at the lattice level which quantify the internal and electrostatic energy associated with 90 and 180 dipole orientati...
متن کاملIonic and electronic conductivity in lead–zirconate–titanate (PZT)
Accurate impedance measurements on differently sized samples of lead–zirconate–titanate (PbZr0.53Ti0.47O3, PZT) have been analyzed with a CNLS procedure, resulting in the separation of the ionic and electronic conductivities over a temperature range from f 150 to 630 jC. At 603 jC the electronic conductivity shows approximately a (PO2) 1/4 dependence, while the ionic conductivity remains consta...
متن کاملThe Effect of Acceptor and Donor Doping on Oxygen Vacancy Concentrations in Lead Zirconate Titanate (PZT)
The different properties of acceptor-doped (hard) and donor-doped (soft) lead zirconate titanate (PZT) ceramics are often attributed to different amounts of oxygen vacancies introduced by the dopant. Acceptor doping is believed to cause high oxygen vacancy concentrations, while donors are expected to strongly suppress their amount. In this study, La3+ donor-doped, Fe3+ acceptor-doped and La3+/F...
متن کاملNonlinear properties of lead zirconate–titanate piezoceramics
Nonlinear properties of lead zirconate-titanate ~PZT! piezoceramics are investigated using ultrasonic second harmonic generation technique. When a sinusoidal ultrasonic wave of frequency v0 is sent into a nonlinear material, the second harmonic wave with frequency 2v0 is generated. Through measuring the absolute amplitude of the fundamental (v0) and of the second harmonic (2v0) waves, the ultra...
