Ferroelectric device or structure and a method for producing ferroelectric devices or structures
The present invention concerns a method for producing at least one ferroelectric device or structure comprising the steps of providing at least one ferroelectric material or layer, or providing at least one ferroelectric material or layer to be patterned o ...
2023Intrinsic-Strain Engineering by Dislocation Imprint in Bulk Ferroelectrics
Dragan Damjanovic, Fangping Zhuo
We report an intrinsic strain engineering, akin to thin filmlike approaches, via irreversible hightemperature plastic deformation of a tetragonal ferroelectric single-crystal BaTiO3. Dislocations wellaligned along the [001] axis and associated strain field ...
AMER PHYSICAL SOC2023Actuation of piezoelectric structures with ferroelectric thin films having multiple elements
A method for driving piezoelectric elements of a micro-system. The piezoelectric elements comprising a ferroelectric thin film, and being configured to be part of any one or a combination of items of a list comprising: a cantilever, a bridge, a diaphragm, ...
2020System and method for ground consolidation
Lyesse Laloui, Dimitrios Terzis, Patrick Gabriel Yihsiu-Ming Hicher
The present invention relates to a method for inducing ground consolidation. The method comprises providing a first chamber (7) in a first hole (3) in the ground (5), and a second chamber (7) in a second hole (3) in the ground (5), the first and second cha ...

2020Electrical energy generated by silicone elastomers filled with nanospring- carbon- nanotubes
Dielectric elastomer generators (DEGs) are flexible capacitors that convert mechanical into electrical energy. They rely on an external voltage source to charge the capacitor during each operation cycle. An alternative to this is an autonomous DEG which op ...
2019Long-range symmetry breaking in embedded ferroelectrics
The characteristic functionality of ferroelectric materials is due to the symmetry of their crystalline structure. As such, ferroelectrics lend themselves to design approaches that manipulate this structural symmetry by introducing extrinsic strain. Using ...
