Domain Pinning: Comparison of Hafnia and PZT Based Ferroelectrics

Paul Muralt, Robin Nigon

Even though many studies on the field cycling behavior of ferroelectric hafnium oxide have recently been published, the issue is still not fully understood. The initial increase of polarization during first cycles is explained by different theoretical and ...

Green paper-based piezoelectronics for sensors and actuators

Danick Briand, Etienne Pierre Lemaire, Christopher John Borsa

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 ...

Fabrication process of silicone-based dielectric elastomer actuators

Herbert Shea, Samuel Rosset, Oluwaseun Adelowo Araromi, Samuel Schlatter

This contribution demonstrates the fabrication process of dielectric elastomer transducers (DETs). DETs are stretchable capacitors consisting of an elastomeric dielectric membrane sandwiched between two compliant electrodes. The large actuation strains of ...

Engineered a/c domain patterns in multilayer (110) epitaxial Pb(Zr,Ti)O-3 thin films: Impact on domain compliance and piezoelectric properties

Nava Setter, Silviu Cosmin Sandu, Andrea Mazzalai, Mahamudu Mtebwa

While there is extensive literature on the influence of both compressive and tensile strain on the domain patterns of (001) tetragonal ferroelectric thin films, little is known regarding domain engineering in (110) films. The primary reason is the absence ...

Non-volatile polarization switch of magnetic domain wall velocity

Nava Setter, Igor Stolichnov, Zhouji Huang

Controlled propagation speed of individual magnetic domains in metal channels at the room temperature is obtained via the non-volatile field effect associated with the switchable polarization of P(VDF-TrFE) (polyvinylidene fluoride-trifluoroethylene) ferro ...

Monitoring of composite structures using a network of integrated PVDF film transducers

Thomas Gmür, Joël Cugnoni, Enrique René Guzman Solares

Aiming to reduce costs, polyvinylidene difluoride (PVDF) film patches are an emerging alternative to more classic piezoelectric technologies, like ceramic patches, as transducers to measure local deformation in many structural applications. This choice is ...
