A study approach on ferroelectric domains in BaTiO3
(2016-10-01)
Atomic Force Acoustic Microscopy (AFAM) and Piezoresponse Force Microscopy (PFM) were used to study local elastic and electromechanical response in BaTiO3 ceramics. A commercial multi-mode Scanning Probe Microscopy (SPM) ...
Influence of the sintering temperature on ferroelectric properties of potassium-sodium niobate piezoelectric ceramics
(2021-01-01)
The effect of sintering condition on structure, microstructure, and ferroelectric properties of (K0.44Na0.52Li0.04) (Nb0.86Ta0.10Sb0.04)- O3 (KNL-NTS) has been investigated. Ceramic powders have been synthesized by the ...
Piezoelectric transducers assessed by the pencil lead break for impedance-based structural health monitoring
(Ieee-inst Electrical Electronics Engineers Inc, 2015-02-01)
The pencil lead break (PLB) is a well-known method for characterizing acoustic emission sensors. In this paper, we analyze the effectiveness of this method in characterizing piezoelectric transducers for structural health ...
Analysis of bistable and chaotic piezoelectric energy harvesting device coupled with diode bridge rectifier
(2015-01-01)
Vibration energy harvesting has greatly expanded over the last few years. While linear vibration-based energy harvesting has received considerable attention in the literature, some current research is focused on the concept ...
Electroactive properties of flexible piezoelectric composites
(ABM, ABC, ABPol, 2001-07)
A flexible piezoelectric composite with 0-3 connectivity, made from Lead Zirconate Titanate (PZT) powder and vegetable-based polyurethane (PU), was doped with small amount of semiconductor powder. As a result a composite ...
