Fractal cluster modeling of the fatigue behavior of lead zirconate titanate
(AIP Publishing, 2002-03-01)
The fatigue behavior of lead zirconate titanate ceramics (PZT) has been studied under electrical and mechanical drives. Piezoelectric fatigue was studied using a mechanical method. Under ac mechanical drive, hard and soft ...
Fe-substituted 0.92Pb(Zn1/3Nb2/3)O-3-0.08PbTiO(3) single crystals: A "hard" piezocrystal
(AIP Publishing, 2002-09-01)
The dielectric and electrically induced strain characteristics of Fe-substituted Pb(Zn1/3Nb2/3)O-3-PbTiO3 single crystals have been investigated. These investigations have shown that Fe substitution results in: (i) a ...
Importance of structural irregularity on dielectric loss in (1-x)Pb(Mg1/3Nb2/3)O-3-(x)PbTiO3 crystals
(AIP Publishing, 2002-06-01)
The dielectric properties of (1-x)Pb(Mg1/3Nb2/3)O-3-(x)PbTiO3 (PMN-PT) crystals have been investigated over a temperature range of 4 to 450 K at various frequencies. At low temperatures, an unusual frequency dependent ...
Correlation between structural deformation and magnetoelectric response in (1-x) Pb(Zr0.52Ti0.48)O-3-xNiFe(1.9)Mn(0.1)O(4) particulate composites
(AIP Publishing, 2007-10-01)
The ferroelectric, ferromagnetic, and magnetoelectric properties of (1- x) Pb( Zr0.52Ti0.48)O-3 - xNiFe(1.9)Mn(0.1)O(4) (PZT- NFM) ceramic composites were found to be dependent upon postsinter annealing and aging. It was ...
Multimodal system for harvesting magnetic and mechanical energy
(AIP Publishing, 2008-09-01)
In this letter, we investigate a multimodal system for simultaneous energy harvesting from stray magnetic and mechanical energies by combining magnetoelectric and piezoelectric effects. The system consists of a cantilever ...
