Investigation of the dielectric and piezoelectric properties of PMN and PMN-PT materials for ultrasonic transducer applications

Abstract

Absnacf--The dielectric and piezoelectric properties of lead magnesium niobate, Pb(MglnNbm)O3 ( P m , and the solid solution systems with lead titanate, PbTiO, (PT), are of importance for investigating the viability of these relaxor ferroelectric materials for sensorlactuator applications. synthesis and processing, atomic-level chemical stnrcture, Fundamental investigations of the relationship between the

Piezoelectric and pyroelectric properties of 65PMN-35PT/P(VDF-TrFE) 0–3 composites

“…In recent years, lead magnesium niobate-lead titanate (PMN-PT) with high piezoelectric properties has been widely studied [1,2]. It is the solid solution of a relaxor ferroelectric lead magnesium niobate (PMN) and a normal ferroelectrics lead titanate (PT).…”

Effect of Compressive Stress on the Ferroelectric Hysteresis Behavior in 0-3 PMN-PT/Cement Composites

“…The benefit from the use of such piezoelectriccement based composite is that these composites possess close matching to the host structure concrete than normal piezoelectric ceramic or other types of piezoelectric composites [14]. In recent years, lead magnesium niobate-lead titanate (PMN-PT) with high piezoelectric property has been widely studied as an alternative piezoelectric material for PZT [15,16]. It is the solid solution of a relaxor ferroelectric (lead magnesium niobate PMN) and a normal ferroelectric (lead titanate PT).…”

Design and Properties of Piezoelectric Vibrator with Generating Function by FEM Analysis

“…The properties of bimorph type piezoelectric actuator are low profile, low power consumption and no Electro-Magnetic Interference (EMI). Also, the generation function can be added in bimorph type piezoelectric actuator [3][4][5]. But the size of piezoelectric vibrator is too larger than DC motor in the previous studies because it is focused at generation properties as a function of physical dimension, and it can't use for mobile phone.…”
