by: Kevin Nadaud, Caroline Borderon, Raphaël Renoud, Micka Bah, Stephane Ginestar, Hartmut W. Gundel, Abstract: Dielectric, piezoelectric and electrostrictive properties of antiferroelectric lead zirconate thin films, elaborated by sol gel on alumina substrates, have been studied as a function of the driving field magnitude EAC. Measurement of the displacement shows that the strain for applied […]

by: Gianni Ferrero, Konstantin Astafiev, Erling Ringgaard, Leonardo Soares de Oliveira, Bhaskar Reddy Sudireddy, Astri Bjørnetun Haugen, Katarina Žiberna, Barbara Malič, Tadej Rojac Abstract: Solid solutions of BiFeO3 and BaTiO3 are promising lead-free piezoelectric materials, especially around the morphotropic phase boundary at 0.67BiFeO3-0.33BaTiO3. Still, these materials are challenged by phase instability and limited understanding of […]

by Damien Brault, Philippe Boy, Franck Levassort, Guylaine Poulin-Vittrant, Claire Bantignies, Thien Hoang and Maxime Bavencoffe Abstract : A typical piezoelectric energy harvester is a bimorph cantilever with two layers of piezoelectric material on both sides of a flexible substrate. Piezoelectric layers of lead-based materials, typically lead zirconate titanate, have been mainly used due to […]
