We report a novel biodegradable piezoelectric composite fabricated from paper and the piezoelectric salt, sodium potassium tartrate tetrahydrate (Rochelle salt, which we term PiezoSalt). The piezoelectric composite is non-toxic and is fabricated free of en ...

Elsevier2016

It has been the dream of many scientists to create polymeric materials which exhibit simultaneously high dielectric permittivity, low glass transition temperature, and excellent elastic properties. Such materials would be a highly attractive dielectric in ...

In-situ structural investigations of ferroelasticity in soft and hard rhombohedral and tetragonal PZT

Dragan Damjanovic

Despite the technological importance of hard and soft PZT, Pb(Zr,Ti)O3, ceramics, the mechanisms of ferroelectric hardening and softening remain widely discussed in the literature. The hardening and softening phenomena have traditionally been investigated ...

Effect of silane coupling agent on the morphology, structure, and properties of poly(vinylidene fluoride-trifluoroethylene)/BaTiO3 composites

Véronique Michaud, Yves Leterrier, Dragan Damjanovic, Sara Dalle Vacche

Micron- and submicron-sized barium titanate (BaTiO3) particles, untreated and surface modified with aminopropyl triethoxy silane, were incorporated in poly(vinylidene fluoride-trifluoroethylene) to fabricate composites with up to 60 vol% of ceramic phase. ...

BiFeO3 Ceramics: Processing, Electrical, and Electromechanical Properties

Dragan Damjanovic

Bismuth ferrite (BiFeO3), a perovskite material, rich in properties and with wide functionality, has had a marked impact on the field of multiferroics, as evidenced by the hundreds of articles published annually over the past 10 years. Studies from the ver ...

Wiley-Blackwell2014

The dielectric response in Bi4Ti3O12 single crystals was studied at subswitching conditions at relative low temperatures (20-250 degrees C) and frequencies (100 mHz to 10kHz) both in-plane and out-of-plane. Electron-holes are likely to be the major charge ...

The transverse piezoelectric coefficient e31,f of Al1-xScxN thin films was investigated as a function of composition. It increased nearly 50% from x = 0 to x = 0.17. As the increase of the dielectric constant was only moderate, these films are very suitabl ...

We report on the use of capacitive self-sensing to operate a DEA-based tunable grating in closed-loop mode. Due to their large strain capabilities, DEAs are key candidates for tunable optics applications. However, the viscoelasticity of elastomers is detri ...

Dielectric properties of K(Ta0.53Nb0.47)O-3 Single Crystal

Nava Setter, Petr Bednyakov, Daniel Rytz

Dielectric properties of K(Ta0,53Nb0,47)O-3 [KTN] single crystals with < 100 > and < 011 > crystallographic orientation were studied. Temperature dependencies of dielectric permittivity of monodomain and polydomain crystals of these orientations are compar ...
