Abstract
This invention provides an electromechanical device comprising an active material comprising a metal oxide such as Ce0.8Gd0.2O1.9 wherein the elastic modulus of metal oxide can be modulated by applying external electric field. The Ce0.8Gd0.2O1.9 layer in a substrateelectrodeCe0.8Gd0.2O1.9electrode structure or conductive substrateCe0.8Gd0.2O1.9electrode structure develops a stress upon applying an electric field. This invention provides methods for tailoring the elastic modulus of materials using an electric field for the generation of an electromechanical response.
