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.
