A Mesoscopic Electromechanical Theory of Ferroelectric Films and Ceramics [PDF]
, 2002 We present a multi-scale modelling framework to predict the effective electromechanical behavior of ferroelectric ceramics and thin films. This paper specifically focuses on the mesoscopic scale and models the effects of domains and domain switching ...

Piezoelectric properties of polyamide 11/NaNbO3nanowire composites [PDF]
, 2012 Polyamide 11(PA 11)/sodium niobate nanowire (NW) 0–3 composites with different volume fractions of NWs were synthesized. The electric polarization (P) was measured as a function of the applied electric field (E).

, 2010 Porous piezoceramics find nowadays many applications as ultrasonic transducers. The introduction of a controlled porosity into a piezoelectric ceramic could in fact strongly improve the acoustic performances for this kind of applications. In this chapter the more recent literature on the processing of porous ceramics has been reviewed.

Piezoelectric nonlinearity and frequency dispersion of the direct piezoelectric response of BiFeO3 ceramics [PDF]
, 2012 We report on the frequency and stress dependence of the direct piezoelectric d33 coefficient in BiFeO3 ceramics. The measurements reveal considerable piezoelectric nonlinearity, i.e., dependence of d33 on the amplitude of the dynamic stress.
