Antiferroelectric Shape Memory Ceramics
Antiferroelectrics (AFE) can exhibit a “shape memory function controllable by electric field”, with huge isotropic volumetric expansion (0.26%) associated with the AFE to Ferroelectric (FE) phase transformation. Small inverse electric field application can realize the original AFE phase. The response speed is quick (2.5 ms). In the Pb0.99Nb0.02[(Zr0.6Sn0.4)1-yTiy]0.98O3 (PNZST) system, the shap...
متن کاملTitle: Shape Memory and Superelastic Ceramics at Small Scales
Shape memory materials are a class of smart materials able to convert heat into mechanical strain (or strain into heat), by virtue of a martensitic phase transformation. Some brittle materials such as intermetallics and ceramics exhibit a martensitic transformation, but fail by cracking at low strains and after only several applied strain cycles. Here we show that such failure can be suppressed...

متن کاملdesign a shape-shifting robot gripper with granular material
in this paper, a new kind of gripper is designed. this universal gripper is proposed where different objects should be gripped easily, reliably within rapid succession without any feedback. by adding an annular balloon around the granular bag, a lateral force pushes the main membrane and increases the friction force between the bag and the load. according to the acquired test results reported i...
متن کاملCeramics: rationale for material selection.
All imaginable types of materials and techniques, from very conservative ceramic restorations to very complex restorations of either metal or high-strength crystalline ceramics veneered with porcelain, have been introduced and tried throughout the years, with varying levels of success. However, there is considerable misinformation and a general lack of published rational treatment planning guid...
