Abstract
The present disclosure relates to an electromechanical actuator, having a stack arrangement made of ceramic basis material having electromechanical properties and electrodes as well as a ceramic insulation for operation/use of the actuator in a humid environment. To ensure a long service life of the actuator with increased electromechanical expansion, an exemplary structure of the ceramic insulation has a smaller average grain size than the structure of the ceramic basis material. A method for the production of an actuator having ceramic insulation and a method for controlling such an actuator are also disclosed.
Claims11
Electromechanical actuator comprising:
- a stack arrangement made of ceramic basis material having electromechanical properties;
- electrodes;
- and
- a ceramic insulation configured for operation of said actuator in a humid environment, wherein a structure of said ceramic insulation has a smaller average grain size than a structure of said ceramic basis material;
- where said ceramic basis material and said electrodes are arranged along a stack axis and said stack arrangement comprises:
- two end faces aligned perpendicular to said stack axis and at least one side surface extending between said end faces, where said ceramic insulation on said at least one side surface extends from one end face to the other end face.
